ATCMF Coriolis mass flow meter

1. The sensor should be placed away from interference source which may cause pipe’s mechanical vibration such as the pump along the process pipeline. If sensors are used in series along the same line, care must be taken to guard against the mutual influence due to resonance. The distance between sensors should be at least more than three times its width. 

2. When installing the sensor, pay attention to the expansion and contraction of the process pipeline due to temperature change. It is strongly recommended that the sensor should not be installed near the expansion joint of the process pipeline. Otherwise, the pipe expansion and contraction of the pipeline will bring about transverse stress which can affect the sensor‘s zero, as a result of which the measurement accuracy will be affected. 

3. The sensor should be placed away from industrial electromagnetic interference sources such as large power motors and transformers, otherwise, the measuring tube’s auto-oscillation within the sensor will be interfered, and the weak signal detected by the speed sensor may be drowned by the electromagnetic noise. Therefore, the sensor should be away from such sources as motors and transformers, at least five meters. 

4. The sensor should be placed in the position where its measuring tube is always filled with fluids and a certain pressure out is maintained, thus it should be placed in the lower end of the pipeline. 

5. Basic requirement: Install the Mass Flowmeter in the lower position of the pipeline so that the fluid can fill with the sensor during the process of zero point calibration and running. The transmitter should be installed in the environment with temperature from -40～+55℃ and humidity <90%. 

6. Dangerous area: Please confirm the installation environment is suitable to the explosion-proof performance indicated in the nameplate of Mass Flowmeter for the installation of dangerous area. 

7. Straight pipe: Mass Flowmeter does not require the special straight pipe upstream or downstream. However, if tow or more mass flow sensors are installed serially in the same pipeline, please ensure the length of pipe between any two sets is more than 2 meters.
