3. The CMB sensor

3.1 Application domain of the CMB sensor

The sensor is intended for use solely for direct and continuous mass flow measurement of liquids and gases, irrespective of their conductivity, density, temperature, pressure, or viscosity. The sensor is also intended for use for the direct and continuous mass flow measurement of chemical fluids, suspensions, molasses, paint, varnish, lacquer, pastes and similar materials.

3.2 Mode of operation

3.2.1 Measuring principle
The Coriolis mass flowmeter is based on the principle whereby in a rotating system a force (known as the Coriolis force) is exerted on a mass at a rotation point that is moving towards or away from this point.

3.2.2 System configuration
The flowmeter consists of a sensor that is mounted in a pipe, and a transmitter (see Section 5 Application domain of the CT on pp. 30), that can be directly mounted on the sensor or installed sepa-
rately (e.g. on a wall).
The transmitter oscillates the flow tubes in the sensor over an excitation coil and picks up, via the sensor coil, the measuring signal which is proportional to the mass flow. After being temperature compensated, the measuring signal is converted into an analog output signal that is consistent with the measuring range setting.

3.2.3 Input
Measured variables: mass flow, density, temperature; volume flow is calculated

3.3 Custody transfer operations

Units designated for custody transfer operation may be certified in accordance to the local or national ordinance. Transmitters ordered for custody transfer applications incorporate special tamper-proof soft­ware, sealed and certified, that prevents the reset of the internal totalizer.

3.5.4 Pressure surges
Pressure surges in a pipe could be provoked by a sudden decrease in flow caused by rapid closing of a valve or similar factors. This change in pressure can lead to underpressure downstream from a valve that has been closed rapidly, and to outgasing. If the valve is mounted directly on the inlet section of the flowmeter, a gas bubble can form in the flow tube that can cause a measuring signal disturbance that would shift the zero point of the output signal. In extreme cases, a pressure surge could cause mechani­cal damage to the sensors and/or flow tube.
Whenever possible, quick-closing valves should be mounted downstream from the sensor. If this is not feasible, such valves are to be mounted a minimum of 10 x DIA (Φ) from the nearest sensor. Alterna­tively, valve closing speed can be reduced.

3.5.5 Using the device with hazardous fluids

The sealing technology used in the standard mass flowmeter renders the device unsuitable for use with hazardous fluids. Only sensors that meet the standards for safety instruments are suitable for use with hazardous fluids.
The pathway between the sensor and transmitter must be pressure-tight so as to prevent fluid from leak­ing out of a sensor in the event a sensor develops a defect.
In the case of welded components, a colored liquid penetration test should be performed on the welds, or one joint (only the first one) should be x-rayed. Alternatively, an internal pressure monitoring device can be used to detect any defect.
3.5.6 Vibration stability
The sensors are insensitive to vibration; vibration stability has been validated in accordance with DIN IEC 68-2-6, for up to 1 g at 10 to 150 Hz.
If pipe vibration is greater than 1 g in the 10-150 Hz range, an additional fastening is to be mounted as shown in the following drawings. This fastening will prevent vibration from affecting the device’s mechani­cal configuration and/or measurement readings. The following drawings are valid for a sensor with a nominal size of approximately 2 inches [DN 040]. Installation is to be realized as shown in this drawing.

3.6.4 Gas content
The use of products containing gas is not allowed for custody transfer operations. In other applications, the presence of gas will increase false readings. In order for the readings of products containing gas to be valid, small gas bubbles must be homogeneously distributed in the fluid. Large gas bubbles will auto­matically provoke extremely false readings and will shift the zero point. Thus, the extent to which readings are false is determined by the process conditions. A rule of thumb in this regard is as follows: A 1 % gas component will increase false readings by 1 %. The gas component is not to exceed 5 %.

4.1 Zero point calibration

In order to ensure that precise measurements are obtained, zero point calibration is to be realized the first time the device is put into operation calibration is to be carried out using a fluid.
The zero calibration procedure is as follows:
• Install the sensor as described in the manufacturer’s instructions.
• Check to ensure that the sensor is completely filled with fluid and that there are no gas bub-
bles in the flow tubes.
• Define the process conditions such as pressure, temperature and density.
• Close a potential shut-off device behind the sensor.
• Operate the transmitter in accordance with the instructions in Section 13.4.4 Zero point cali-
bration on page 61.
• Make sure that sufficient time is allowed for the electronics to warm up.
• Allowing fluid to flow through the sensor during the zero calibration procedure will skew the
zero point and result in false readings.
4.2 Startup conditions
The device is not subject to specific startup conditions. However, pressure surges should be avoided.

6.1 Measuring principle
The Coriolis mass flowmeter is based on the principle whereby in a rotating system a force (known as Coriolis force) is exerted on a mass at a rotation point that is moving towards or away from this point. By configuring the sensor in a specific fashion, this force can be used to measure mass flow directly. The CT transmitter evaluates the sensor signal (see Section 3.2.1 Measuring principle on page 14).

CMB & CT OPERATING MANUAL
6.2 System configuration
Transmitter: The CT transmitter regulates the excitation of the sensor vibration system and processes the sensor sig­nals. The standard model is equipped with two analog 0/4 to 20 mA outputs, an impulse or frequency output and a status output, and is enabled for digital data transfer via the HART also available with a Profibus-PA field bus.
Sensor: The CMM, CMB and CMU sensors measure flow, density and temperature in fluids. The device can be used to perform measurements with any liquid or gaseous product providing that the sensor material is suitable for the product being used.

6.2.1 DSB data memory module

The replaceable plug and play memory module is mounted on a printed board and stores all sensor data such as sensor constants, model numbers, serial numbers, and so on. Consequently, the memory mod­ule is linked to the sensor and is attached to the transmitter housing with a nylon cord.
If the transmitter is replaced, the memory module should be transferred to the new transmitter. When the flowmeter is started up, the device continues using the values stored in the memory module. Thus, the DSB memory module provides maximum safety and comfort when device components are replaced.

12. Control unit BE2
12.1 Introduction
The CT transmitter can be operated using control unit BE2, a desktop or laptop computer in conjunction with SensorPort software, or via HART
In the following, transmitter operation and parameterization using control unit BE2 (normally integrated into the terminal compartment) are described. The control unit can also be connected to the transmitter using an intrinsically safe cable that is up to 200 m in length. This allows a point-of-use display to be in­stalled in a control room so that readings, counter status and settings can be accessed ergonomically.
®
Communicator.
12.2 Display
Control unit BE2 in the CT has an integrated alphanumeric display with two 16-character lines (format 16 x 60 mm). Measurement data and settings can be read directly from this display.
The LCD display is designed be operated at temperatures ranging from − 20 °C to + 60 °C (-4° F to 140 °F) without incurring any damage. However, at freezing or near-freezing temperatures, the display becomes slow and readability of the measured values is reduced. At temperatures below − 10 C° (14 °F), only static values (parameter settings) can be displayed. At temperatures exceeding 60 C° (140 °F), con­trast decreases substantially on the LCD and the liquid crystals can dry out.

13.4.4 Zero point calibration
Using the

Zero point calibration function the operator can recalibrate the zero point of your meter in the

measuring system. Zero point calibration is to be realized after any installation procedure or after any type of work has been performed on in the pipes near the sensor.
CAUTION:
This function may only be carried out if it is certain that the fluid in the sensor is not flow­ing. Otherwise, the flow rates measured subsequently will be incorrect. The sensor may be completely empty or filled with fluid. A partially filled sensor or air bubbles will lead to an incorrect zero point calibration.
Calibrating a sensor filled with a fluid is better than calibrating an empty one.

Part No 06EN003384 rev. 1.6
After selecting the frequency setting, the maximum frequency of 1 kHz will be generated when the upper­range value for mass or volume flow is reached (depending on the selected pulse unit). If the flow rate falls below the low flow volume, the actual frequency is 0 Hz.
After selecting the pulse setting, pulse value and unit, the transmitter will determine the number of pulses per flow volume. When choosing a combination of these settings that cannot be fulfilled in real time for the upper-range value (e.g. the number of pulses per time unit cannot be generated due to the pulse width which is too large), the error message “Pulse width too large” or “Inconsistent parameter” will be displayed.

As mentioned in Section 12.4.3.1 Selection window/make a selection, the operator can choose between the following settings:
¾ Direct pulse and current outputs are programmed directly ¾ QM, D, T a measurement is simulated
If “direct” simulation is activated, any output will perform based on the settings described in Sections
13.11.4.1 Status output simulation to 13.11.4.4 Simulation current output I2. It is therefore recommended that the settings be defined before starting simulation. They can then be purposefully changed during simulation.
The status of the outputs during measured value simulation based on the setting “QM, D, T” depends on the selected simulation values of these three variables, the measuring range settings and the assignment of the outputs. If, for example, the pulse output is assigned to volume measurement, it will be affected by all three simulation values at the same time [V ≈ QM (T) / D (T)].
Simulation will be deactivated automatically if the operator switched the device off or did not touch
any control unit keys for about 10 minutes.

13.14.1 Sensor constant C
Sensor constant C is the sensor calibration value for mass flow. This constant is defined when the flow­meter is calibrated at the factory and can be found on the rating plate.
Sensor constant
+0150.00 kg/h
CAUTION:
Changing sensor constant C to a value that differs from the value on the rating plate of the sensor connected to the flowmeter will result in false readings.

CMB & CT OPERATING MANUAL
Normally, the sensor constant is changed only when the device is calibrated, e.g. for a validation meas­urement for a custody transfer operation.
Note:
The sensor constant must always be preceded by a plus or minus sign. The delivery de­fault setting is a plus sign. If inlet and outlet section are interchanged when the device is installed (the flow direction is indicated by an arrow on the sensor), the transmitter will display a “forward flow” negative measurement value. If the (plus or minus) sign of the sensor constant is then changed without changing the actual value, a plus sign will again be displayed. No changes need be made in the disposition of the electrical connections (wires).
13.14.2 Sensor material
The

Sensor material function allows the flow tube material code to be entered. This material code can be

found on the sensor rating plate. This setting is defined by the vendor when the device is first put into operation at the factory.

14. Use of the CT for custody transfer operations
The CT functions are basically the same in Standard mode and Custody transfer mode. In both modes, the various CT security mechanisms are activated in compliance with international standards for custody transfer operations OIML R 105 and DIN 19217. However, the following additional factors come into play for custody transfer procedures.
14.1 Programming the transmitter
If the device is to be verified at a later time, the settings in the following table should be used:

14.2 Binary input (resetter)
A pushbutton is connected to the binary input. To switch the counter display to a higher level of accuracy, hold this pushbutton down for less than 3 seconds and then release it. After about 1 minute, the display will automatically revert to the standard status. For better readability, the count this process.
To delete an error message and start the display test sequence, hold the pushbutton down for at least 5 seconds. During the display test, all digits (0 to 9) will be displayed at each of the 16 positions on each line of the display. This allows for detection of any defect in, damage to, or tampering with the display. .

14.3 Self-test error
When the device is in Custody transfer mode, a self-test error message will remain on the display until it is cleared by pressing the external resetter pushbutton.

14.4 Verification stamp/stamp position
The transmitter will operate like a standard transmitter as long as no verification stamp has been affixed to it. This means that all settings that are allowable for customers are accessible, including on-site cali­bration. Once the verification stamp has been affixed to the transmitter (closing a jumper in the electron­ics compartment on the CPU printed board of the UMC3-30), no settings can be changed. After the verifi­cation stamp has been affixed, the SG1 housing is screwed on and sealed with leads.
Stamp position
The UMC3-30 printed board in the electronics compartment (SG1 housing) contains a jumper that indi­cates that the device is in Custody transfer mode. Once this jumper has been closed, no settings can be changed and the CT operates in Custody transfer mode.

14.5 HART® communication in Custody transfer mode
Measured values can be transmitted and parameters can be read without restriction when the device is in Custody transfer mode. However, any attempt to change settings will be denied, which of course means that counts cannot be changed either.

15. CT transmitter error messages
The integrated CT transmitter distinguishes between two types of errors. Self-test errors such as prob­lems with a sensor line or inconsistent parameter inputs are displayed as text error messages. Once the error has been eliminated, the message automatically disappears from the display. For further informa­tion, see Section 15.3.1 Display of self-test errors.
Errors that are attributable to system memory or software, division by zero, or a fault in the electronics unit are designated as system errors. These error messages are not reset automatically after the error (usually of very brief duration) is eliminated.

If the cause of any of the error messages described below cannot be eliminated, contact the device ven­dor.
15.1 Standard operating mode
The transmitter operates as described above. After the cause of the error message has been eliminated, the message automatically disappears. The self-test for monitoring the excitation current can be activated or deactivated via the “Sensor test” function.
Before resetting a system error manually, we advise that
