Normally Thermal Mass Flow Meter Problems and Troubleshooting
After checking out above issues, please process trouble shooting according to following description.
Problem | Possible Cause | Solution |
Velocity measurement is erractic or fluctuating | Very erractic or non-uniform flwo | Follow installation requirements shown in Comate thermal mass flow meter manual |
Flow meter installed with less than required minimum pip diameters upstream and dlown stream of the sensor | Follow installation requirements shown in Chapter 2 | |
Insertiong sensor probe not mounted securely | Sensor probe must be mounted securely without vibration | |
Earthing circuit loop | Wire the meter according to the introduction in Comate thermal mass flow meter manual | |
Liquid contains in fluid | Install a water filter in upstream of the meter | |
Sensor failure | Return to factory for evaluation | |
Transmitter failure | Return to factory for evaluation | |
The measuring flow is too high or too low | Sensor is not inserted to the middle of the pipe line | Please fix the sensor in the middle of the pipeline |
The flowmeter is not vertical to the center line of the pipe line | Re-install the meter and make the probe vertical to the center line of the pipe line | |
No flow measured | The limit of small signal cut off is set too high | Set the small signal cut off limit to a lower and proper value |
The flow rate in pipeline is smaller than the lower limit of the meter | Contact the supplier | |
The flow rate in pipeline is larger than the higher limit of the meter | Contact the supplier | |
Flow profile distortion | Try to find another location for the meter | |
Sensor failure | Return to factory for evaluation | |
Transmitter failure | Return to factory for evaluation | |
Extremely turbulent flow | Do not place the meter near a ventilator static mixer or valve |
COMATE innovative technology Bluetooth function
All above manual need support by users. And COMATE innovative technology Bluetooth function will release your hand and saving your time.
This function enable users who have COMATE flow meter in site to reach and configure the parameters more easy rather than loose the case and check the manual how to set it. Most important is COMATE R&D team will help you to do this job just get the device online and click online diagnosis, our team-member will collect the data and help you to check where the problems may come from!
