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).
