Cheap thermal gas mass flow meter supplier china has two parallel t-shaped vibration tubes inside the sensor, a drive coil is installed in the middle, and vibration pickup coils are installed at both ends. Cheap thermal gas mass flow meter supplier china directly measures the mass flow of the medium passing through the flowmeter, and can also measure the density of the medium and indirectly measure the temperature of the medium. Cheap thermal gas mass flow meter supplier china is an important flow measurement instrument. The mass flowmeter adopts the heat sensing measurement. Then this paper mainly introduces the solution to Cheap thermal gas mass flow meter fault.
In general, Cheap thermal gas mass flow meter supplier china will not fail, and it does not matter if it fails. Careful analysis of the causes can solve the problem, such as whether the working condition has changed, whether there is gas, whether it has just been calibrated back for use, and so on. Here is a brief introduction of several types of Cheap thermal gas mass flow meter supplier china failures and their solutions:
Cheap thermal gas mass flow meter supplier china fault handling - hardware fault
If the error is too large, the integrator display does not light up or increase in value, and the display is blank, the causes are as follows:
a. The installation of Cheap thermal gas mass flow meter supplier china is not standardized, which can directly lead to the zero drift of Cheap thermal gas mass flow meter supplier china. For example, Cheap thermal gas mass flow meter supplier china is installed near the pump outlet, the sensor support strength is not enough, the connection flange is improperly welded, and the stress signal is generated, and the cable is subject to electromagnetic interference.
b. Wiring problem of Cheap thermal gas mass flow meter supplier china
If the display does not light up, check the power connection of the totalizer. If the fuse is burnt, confirm whether the input voltage is consistent with the nominal value of the standard voltage and the AC/DC form. In addition, if the integrator does not increase with the flow, check the connection of the integrator. If the integrator is equipped with a forward/reverse program, check the connection of the flowmeter. Because the connection of Cheap thermal gas mass flow meter supplier china is incorrect, the integrator will not increase in reverse flow.
c. Change of process medium of Cheap thermal gas mass flow meter supplier china
In case of air entrainment, gasification or two-phase flow in the measuring medium, the transmitter will display an alarm, and the sensor will stop working in serious cases.
d. Transmitter failure of Cheap thermal gas mass flow meter supplier china
e. Sensor failure of Cheap thermal gas mass flow meter supplier china
f. Pipeline purging problem of Cheap thermal gas mass flow meter supplier china
Software problems of Cheap thermal gas mass flow meter supplier china
Fault handling of Cheap thermal gas mass flow meter supplier china - before installation and use of Cheap thermal gas mass flow meter supplier china that has just been calibrated, attention must be paid to the zero calibration under the current working condition. It must be ensured that Cheap thermal gas mass flow meter supplier china is filled with media before the zero calibration can be performed by closing the stop valves at both ends. There are many specific methods, including panel operation, manual operator and using pro Ⅱ software.
a. Zero calibration error.
b. The parameter setting is incorrect.
c. Pulse fluctuation of power supply.
d. I/o configuration error (be sure to pay attention to the range).
e. Operation error.
