Troubleshooting of Gas Mass Flow Meters

The volume of the fluid is a function of the temperature and pressure of the fluid, and is a dependent variable, while the mass of the fluid is a quantity that does not change with changes in time, space temperature, and pressure. As mentioned earlier, in the commonly used flowmeters, such as orifice flowmeters, turbine flowmeters, vortex flowmeters, electromagnetic flowmeters, rotor flowmeters, ultrasonic flowmeters and oval gear flowmeters, the flow measurement values ​​are fluid. volume flow. The amount of fluid involved in scientific research, production process control, quality management, economic accounting and custody transfer is generally mass. Using the above-mentioned flowmeter to only measure the volume flow of the fluid often cannot meet people's requirements, and it is usually necessary to try to obtain the mass flow of the fluid. In the past, the quality of the fluid could only be obtained indirectly by means of correction, conversion and compensation after measuring parameters such as temperature, pressure, density and volume of the fluid. If the hardware failure of gas mass flowmeter has a large error, the display of the totalizer is not bright or does not increase in value, and the display is blank, the reasons are: a. The installation is not standardized, which can directly lead to zero drift of the flowmeter, such as mass flowmeter installation The pump outlet is close, the sensor support strength is not enough, the improper welding of the connecting flange produces stress signals, and the cable is subject to electromagnetic interference. b. Wiring problems If the gas mass flowmeter does not light up on the display, check the power connection of the totalizer. If the fuse is burned, confirm whether the input voltage is consistent with the nominal value of the standard voltage and whether the AC and DC forms are consistent. If the totalizer does not increase with the flow rate, check the totalizer wiring. If the totalizer is equipped with a forward/reverse program, check the flowmeter wiring. Because the flowmeter wiring is incorrect, the totalizer will be reversed. Does not increment when flowing. c. Process medium change If the measurement medium has phenomena such as air entrainment, gasification or two-phase flow, the transmitter will display an alarm, and in severe cases, the sensor will stop working. d. Transmitter failure. e. Sensor failure. f. Pipe purging problems. Troubleshooting of mass flowmeters for software problems—For the flowmeter that has just been calibrated, be sure to pay attention to the zero-point calibration under the current working conditions before installing and using it. It must be ensured that the flowmeter is filled with medium and the stop valves at both ends are closed before zero-point calibration. There are many specific methods, such as panel operation, hand communicator and using prolink II software. a. Zero calibration is wrong. b. The parameter setting is incorrect. c. Pulse fluctuations of the power supply. d.i/o configuration is wrong (be sure to pay attention to the range). e. Operation is wrong

is emerging as one of the most popular mass flow meter, moving beyond its rosemount coriolis mass flow meter benefits, with conclusive scientific evidence suggesting the positive role play in rosemount vortex flow meter.
