In order to improveMass Flow MeterIt is necessary to control the installation quality of the sensor. For different process media, the sensor can have different installation forms, such as upward, downward and mark. During the installation process, attention needs to be paid to avoid the sensor being affected by large vibration and stress.

In order to control vibration interference, ground support can be added to the sensor inlet pipe, and the vibration is transmitted to the ground through the support pipe. In order to avoid stress interference, it is necessary to ensure the concentricity of the sensor outlet and inlet. When selecting flanges, you need to determine the distance between the sensor connecting flanges. Although there are not many requirements for installing mass flow meters in straight pipes, during the actual installation process, try to avoid installing them at pipe diameter reductions and elbows to reduce the impact on the fluid and reduce the occurrence of disturbances.

The installation of a mass flow meter is highly sensitive to torsion. During the actual installation process, it is necessary to control the impact of torsional stress on the mass flow meter as much as possible. If the stress is too large, the flow error will exceed the tolerance range. Installing metal hoses can eliminate pipe stress, avoid the impact of vibration on the mass flow meter, and ensure that the accuracy of the mass flow meter meets the accuracy grade requirements.

Perform pressure compensation.

Pressure compensation mainly refers to the compensation of sensor measurement accuracy through the flow meter transmitter under calibrated pressure conditions. At the beginning of the design of the mass flow meter, the mass measurement principle was applied. People often mistakenly believe that the measurement accuracy of mass flow meters is not affected by changes in process pressure. In the process of popularization of mass flow meters, people began to realize the impact of process pressure on the measurement accuracy of mass flow meters. Through analysis, it was found that if the process pressure deviates from the calibrated pressure, the sensitivity of the sensor will change greatly, and measurement errors will occur. Mass flow meters are widely used in custody transfer, and their small errors will bring great economic benefits, so more attention needs to be paid to their errors.

Temperature compensation for mass flow meters.

As long as it is a fluid, its density will change with changes in temperature and pressure parameters during the measurement process. In order to reduce the impact of temperature on the measurement results, temperature compensation needs to be performed. When installing the instrument, set it up and input a temperature signal that meets the instrument's requirements. The instrument will be in a dynamic compensation state from the ultrasonic flow meter, thereby automatically calibrating the fluid density under the current working conditions and displaying the flow parameters.
