The UFM 3030 ultrasonic flow meter is a precision instrument designed for linear, bi/directional flow measurement of liquids. Flow measurement values can be output via the standard analog and-or pulse/frequency outputs. Via a user friendly operator interface (HMI) the unit can be set up for a wide range of applications. Next to actual volumetric flow measurement the unit can be configured to perform flow totalization (plus, minus and sum). Also measurement and output of the liquid sonic velocity can be configured. Optionally the unit can be set to perform one of the following additional functions:

•

Calculate and output corrected standard volumetric or mass flow using the external pressure

• and temperature inputs function

•

Heat function, combining T1, T2 and volume

6 UFM 3030

The UFM 3030 consists of a flow sensor (UFS 3000) and a signal converter (UFC 030), which can be built into a compact flow meter, UFM 3030 K or a separate flow meter, UFM 3030 F.

Both flow sensor and signal converter are available with an approval for use in hazardous areas.

Special codes and regulations apply in these areas and are referred to in the instructions for hazardous area versions, supplied as a separate manual.

2.1 Handling the flowmeter

Important: Do not lift the compact flowmeter by the signal converter housing or the terminal box. Check the weight of the flowmeter as indicated on the type plate before handling the unit.

When handling the flowmeter avoid hard blows, jolts or impacts.

Do not place the flowmeter on the signal converter housing.

2.2 Installation location and position

The UFM 3030 flow meter can be installed in horizontal, slightly ascending or vertical pipelines.

If installed in a horizontal or slightly ascending pipeline, always install the converter or terminal box in vertical position opposite the flow sensor either with the converter up or down, but never in horizontal position.

8 UFM 3030

If required the position of the signal converter can be modified by turning the display circuit board through 90° or 180° to achieve a horizontal position of the display. In addition the signal converter housing may be turned through 90° opposite the flow sensor.

For an exact description of this procedure, refer to chapter 8.6.

The measuring tube must be completely filled at all times for proper flow measurement, as the sensors become non-wetted, a loss of signal message will be displayed. There is no damage when this occurs.

Flow direction. The UFM 3030 is a bi-directional flow meter. Note the indicating arrow for the positive direction on the flow meter.

It is recommended to protect the signal converter from direct sunlight to prolong the life. Although no direct damage will occur, installation of a sunshield is advised.

Do not expose the signal converter to excessive vibration. To protect the flow meter from excessive vibration support the pipeline on either side of the flow meter.

Make sure there is sufficient room next to the pipe flanges to fit the bolts and nuts.

To achieve the specified accuracy of the flow meter, a straight inlet section of 10 × DN (DN = meter size) and an outlet section of 5 × DN should be applied.

Normally zero setting is not necessary, but if required the zero point can be checked and the meter can be re-zeroed under stationary flow conditions (see Function 1.01.03 of the converter menu). To force zero flow, a shut-off valve should be provided upstream and/or downstream of the flow sensor.

Mixing different fluid products. Install the flow meter upstream of mixing point or at minimum distance of 30× DN (DN = meter size) downstream of the mixing point, otherwise the flow measurement may be unstable.

Ambient temperature all flow meters: -40 to +65°C/ -40 to +149°F

Product temperature compact flow meter: -25 to +140°C/ -13 F to +284°F

Product temperature separate flow meter: -25 to +180°C/ -13 to +356°F

Special versions are available for higher process temperatures.

In case of a pipeline running along a wall: please observe a minimum distance between pipe centreline and the wall of at least 0.5 m (1.6 ft).

2.3 Special installation requirements

To avoid measuring errors and malfunctioning of the flow meter due to gas or air inclusions or an empty pipe, please observe the following precautions:

9

Since gas will collect at the highest point of a pipe, installation of the flow meter at that location should be avoided at all times. Also installation in a down going pipe should be avoided since a completely filled pipe may not be guaranteed due to cascading affects. Additionally flow profile distortion is possible.

Long horizontal pipes: install in slightly ascending pipe section. If not possible, ensure adequate velocity to prevent air, gas or vapour from collecting in upper part of flow tube As a partially filled meter will report higher than actual flow rates, or not measure (as transducer pairs become non-wetted).

Open feed or discharge: Install meter in a lowered section of the pipe to ensure a full pipe condition through the meter.

Down going pipeline over 5 m (16 ft) length: install air vent downstream of the flow meter. To prevent vacuum. While this will not harm the meter, it may cause gases to come out of solution (cavitate) and interfere with proper measurements.

Always install control valves downstream of flow meter in order to avoid cavitation or distortion of flow profile.

Never install flow meter on a pump suction side in order to avoid cavitation or flashing in the flow meter.

Refer to dimensional drawings for flange spacing and in addition allow for thickness of gaskets.

Install flow meter in line with pipe axis. Pipe flange faces must be parallel to each other, max.

Permissible deviation: Lmax — Lmin

≤

0.5 mm

(0.02″).

10 UFM 3030

2.5 Pipes with cathodic protection

Pipes with electric corrosion protection are generally insulated inside and outside so that the fluid has no conductive connection to ground. The flow meter must be insulated from the pipe. Note the following when installing the flow meter:

The pipe flanges must be connected to each other using a copper cable (L), but must not be connected to the flow meter.

The bolts for the flange connections and the gaskets must be insulated. Use sleeves and washers that are made of insulating material (these must be provided by customer).

1. Flange of flow sensor

2. Gasket

3. Pipe flange

4. Bolt

5. Nut

6. Washer

7. Insulating sleeve

«zero» flow in the pipeline (measuring tube completely filled with medium. Function 3.01.02 ZERO

VALUE can be used for zero calibration. It can be set to either FIXED, which will give a factory zero setting, or MEASURED, which will allow to compensate for the small signal using Function 3.01.03

ZERO CAL.

Function 3.01.04 Master time constant of display and outputs

This is the time that it takes for the display and the current and pulse outputs to reach 66% of the end value, after a change in the flow rate. The time constant does not apply for totalisation. The time constant does not apply for the current output in F/R setting.

If required, a different time constant value can be set for the pulse/frequency output under Function

3.05.06 TIME CONST.

Function 3.01.05 through 3.01.07 Low-flow cut off for display and outputs / Cut off «on» value/ Cut off «off» value

Due to the extreme low flow sensitivity of the UFM 3030, it will detect the slightest movement of fluid, even at zero flow. To avoid these measurements causing outputs and Totalizer changes, the low flow cut-off can be used to force reading to zero. These are set as a percentage of Full Scale, as configured in Fct.1.01.01 or 3.01.01.

When the flow rate decreases below the «on» value, the display and outputs are set to their «zero» values. When the flow increases above he «off» value, measurements are resumed. The «off» value must be larger than the «on» value by at least 1%. With Function 3.01.05 LF CUTOFF set to NO, factory settings are used for the «on» and «off» values.

Function 3.01.08 Meter size

The nominal diameter of the measuring tube. See the flow sensor nameplate. This value can be entered In mm or in inches.

Function 3.01.09 Flow sensor constant GK

At the factory, each flow sensor is calibrated and supplied with a calibration constant. This constant can be found on the flow sensor nameplate.

30 UFM 3030

Function 3.01.10 Definition of forward flow direction

The forward flow direction is indicated with an arrow on the flow sensor. If the actual flow is in the direction of the arrow then the flow is in the positive direction and the converter will have a positive flow reading. By setting this function to NEGATIVE, the converter’s reading can be reversed. This can be useful when the process flow direction is changed so the flow sensor will not need to be reversed.

Function 3.01.11 through 3.01.12 Minimum/Maximum velocity of sound

In media of varying composition, the ultrasonic wave speed will vary, like in oil-water mixtures. This is identifiable by means of measuring the velocity of sound. The current output and the pulse output can be programmed to indicate the velocity of sound, see Function 3.04.01 and 3.05.01. Their

«zero» values (0% scale) will then correspond with the velocity of sound set in Function 3.01.11 MIN

VOS, where their «full-scale» values (100% scale) will correspond with the velocity of sound set in

Function 3.01.12 MAX VOS. See also Function 3.03.06 VOS for the display of the velocity of sound. NOTE: Only necessary for setting span for outputting VOS, is not needed to measure flow!

Submenu 3.02.00 Version

Function 3.02.01 Function of converter

This function is factory pre-set, and can be changed between STANDARD and the appropriate version that is defined in the converter’s hardware. The following versions are possible:

STANDARD, standard functionality

CORR T version with temperature correction of the measured flow, using analog input 1

CORR T+P version with temperature- and pressure correction of the measured flow, using analog inputs 1 and 2

HEAT version, reserved for measurement of heat power and heat energy totalisation.

BATCH version for batch volumes.

The batch function can be used for repetitive dosing of a fixed volume. It provides simple single stage batching. A batch volume can be set using FUNCTION 3.2.13. The digital input is used to start a batch, see FUNTION 3.6.1. The digital output is used to indicate that the set batch volume has been reached, see Function 3.5.1. The forward flow Totalizer counts the actual batch volume and is reset at the start of every new batch. The reverse flow Totalizer counts the total of all batches.

The following table gives an overview of the additional features of each version, in comparison with the standard version.

Remark: with every change from a converter function to STANDARD, the Totalizer is switched off.

Function 3.02.02 through 3.02.07 4/20 mA Reference for analog input 1/2

These functions are available depending on the version (see Function 3.02.01). The analog inputs are supplied with the 4-20 mA current range signal coming from the temperature- and pressure transducers. Their 4 mA and 20 mA values represent a certain temperature- or pressure value, which must be defined in these functions.

Function 3.02.08 through 3.02.11 Product constant K0/K1/K2 /Product density at T = 15 °C

Calculation of the corrected volume.

Only available for the CORR T or CORR T + P version (see Function 3.02.01).

One of the features of the 3-beam ultrasonic flow meter is the capability of calculating the corrected volume. Corrected volume calculation can be carried out either based on temperature compensation or based on temperature and pressure compensation.

The corrected volume is calculated to standard conditions defined as 15°C and, if applicable,

1.01325 Bara. For this purpose the analog inputs are set to connect a temperature transmitter and a pressure transmitter. For accurate calculations it is advised to calibrate the individual P and T instruments.

The corrected volume is calculated from the following formula:

Vcorrected = Vactual * VCF

Vcorrected = calculated corrected volume at standard conditions i.e. 15

°

C and 1.01325 bara

Vactual = actual volume measured by the 3-beam flow meter

VCF = Volume Correction Factor and is calculated from [Ctl x Cpl]

32 UFM 3030

The calculation of the Volume Correction Factor is based on the standards of the American

Petroleum Institute (API), and consists of two individual correction factors: chapter 11.1 standard

2540 for calculating the temperature correction (Ctl) and chapter 11.2.1 M for calculating the pressure correction (Cpl).

The correction for the influence of temperature on liquid (Ctl) is calculated from:

Ctl = EXP [-

α t (Tactual — 15) * (1 + 0.8

α t (Tactual – 15))]

Tactual = actual liquid temperature [°C]

α t = thermal expansion coefficient

The thermal expansion coefficient

α t is calculated from the standard density at 15°C and three constants of the measured product (K0, K1 and K2).

As a rule of thumb the volume correction factor can be estimated as 0.1% per degree Celsius.

Correction for the influence of pressure on liquid (Cpl)

When the feature has been selected for the compensation of the measured volume for the influence of temperature and pressure, no extra parameters have to be programmed for the pressure correction. The calculation of this pressure correction is only depending on the given standard density at 15°C. Based on the density the compressibility factor is calculated from the following mathematical model:

F = EXP [-1.62080 + 0.00021592 * tactual + 0.87096/

ρ

15 *10-6 + 0.0042092 * tactual/

ρ

15 * 10-6]

Tactual = actual liquid temperature [°C]

ρ

15 = density at standard condition i.e. at 15 °C [kg/m3]

By using this calculated compressibility factor the Correction for pressure is calculated from:

1 Cpl = 1/ 1-F * Pactual*10-4

F = compressibility factor

Pactual = absolute actual pressure [bar]

As a rule of thumb the volume correction factor can be estimated as 0.01% per bar (0,00068% per

PSI)

With the fluid density entered and the corrected volume calculated, the corrected volume flow can be displayed as mass flow. This can be done as follows:

3.1.1. Set the unit to free user definable unit (**********)

3.7.5. Set the required unit text e.g. kg/hr.

3.7.6. Set the amount of mass per m3 in the unit as displayed e.g. kg.

Function 3.07.09 through 3.07.11 Plausibility filter

A plausibility filter can be set for the sensor measuring paths. There are 3 settings; an error limit, an error counter decrease step value and an error counter limit.

Every measured value outside the error limit is not processed and will increase an internal plausibility counter by 1, until a counter limit has been reached. The corresponding measuring path will then be made inactive. The error limit is set using function 3.07.09. Range: 1 through 99%, default setting: 20%.

The counter limit is set using Function 3.07.11. Default setting is 0, the function is switched off.

Every measured value within the error limit will decrease the internal plausibility counter by the number programmed in Function 3.07.10. The higher the number the faster an inactive measuring path will become active again. Range: 1 through 99, default setting: 4.

Whenever one or more measuring paths are made inactive, the display compass field will indicate that, combined with the display of error messages. Also see Section 5.1.

Part D Technical Data

10 Dimensions

Go to the technical datasheet. The latest version of the technical datasheet (and other documentation) can be found on the KROHNE Download Center via www.krohne.com

. You will also find a digital copy on the product information CD that is delivered with the product.

The converter consists of four functional groups.

•

Functional group 1 generates the ultrasonic waves, controls the sensors and carries out highprecision measurement of the propagation time by means of a digital signal processor (DSP).

•

In functional group 2 the digitised data supplied by the DSP are evaluated by microprocessor P

2 in accordance with the functions, operating and flow sensor data which are factory set. The

DSP data and data from the galvanic isolated inputs is used to calculate the various flow values.

In turn, the galvanic isolated output circuits are updated. In the event of a power failure, last counts are saved in EEPROM 2. In the same way as operating and functional check data are permanently stored in EEPROM 1. Both are retained for 10 years without auxiliary power.

•

Functional group 3.This group is galvanically isolated from the other groups. It consists of various outputs (current and pulse) and inputs (digital and analog). All input/output circuits share the same common.

•

Functional group 4 Power supply. The power supply is a switching, high efficient module with a wide input range. Two variations of the power supply are available. One for high voltage AC supply and one for low voltage AC/DC supply. The AC power supply has a wide range from 85 to 265 Volts.

46 UFM 3030

12.1 Transit time differential method

UFM 3030 operates just like all KROHNE ultrasonic flow meters by the transit-time differential method. This measuring principle is based on a simple physical fact. Imagine two canoes crossing a river diagonally, one with the flow and one against the flow. Naturally the canoe that is travelling with the flow will reach the opposite side sooner that the canoe that is travelling upstream. Acoustic signals behave in a comparable way.

By means of ultrasonic sensors in the UFM 3030 the transit time of acoustic signals that travel upstream and downstream are measured. The difference in transit time is proportional to the mean flow velocity and is transformed into an output signal by the electronics.

L= acoustic path length

Vm = flow velocity of the medium

The three measuring beams in a UFM 3030 make a threedimensional cross section of the medium that flows through the measuring tube. These measuring lines are positioned that the influence of the flow profile (laminar or turbulent) are largely reduced. Combined with the use of the latest signal processing techniques (DSP) this results in a stable and reliable measurement.

12.2 Three beam ultrasonic measurement

The flow velocity measurement of the 3-beam ultrasonic flow meter is based on measurement at three positions in the measuring tube. Two of the acoustic beams are located in symmetrical arrangement on the outside and the third beam is located in the centre of the measuring tube.

Each individual acoustic path of measurement forms an angle ϕ

with the tube centerline.
