1. There is a problem with the quality flow meter, and the flow rate is not controlled. Seeking help is not unfamiliar to us. We have gained a certain understanding of its basic working principle and application fields. But what if the quality flow meter malfunctions? In our general use, if we encounter a strike phenomenon of the flow meter, can we promptly identify the problem with the flow meter and find the corresponding solution. Below, we will briefly introduce Ziyou Instruments solutions to common problems with quality flow meters and their corresponding solutions.
1、 Hardware failure of quality flowmeter: If there is a large error, the accumulator does not light up or increase value, or the display is blank, the reasons are: a. Improper installation can directly cause zero drift of the flowmeter. For example, if the quality flowmeter is installed close to the pump outlet, the sensor support strength is insufficient, the connection flange welding is improper, which generates stress signals, and the cable is affected by electromagnetic interference. b. If the display does not light up due to wiring issues, check the power connection of the integrator. If the fuse is blown, confirm that the input voltage is consistent with the nominal value of the standard voltage and whether the AC and DC forms are the same. If the accumulator does not increase with the flow rate, the wiring of the accumulator should be checked. If the accumulator is equipped with forward/reverse programs, the wiring of the flow meter should be checked. Incorrect wiring of the flow meter can cause the accumulator to not increase in reverse flow. c. If there is gas entrapment, gasification, or two-phase flow in the measured medium due to c
2、 For software issues with quality flow meters, it is important to pay attention to zero calibration under current operating conditions before installing and using a newly calibrated flow meter. It is necessary to ensure that the flow meter is filled with medium and close the shut-off valves at both ends before zero calibration can be performed. There are many specific methods, such as panel operation, manual operation, and using ProLink II software. a. Zero calibration is incorrect. b. Parameter settings are incorrect. c. Pulse fluctuations of the power supply. d. The I/O configuration is incorrect (be sure to pay attention to the range). e. Operation error.
2. Emerson Quality Flow Meter Fault Frequency Output Saturation Solution!
When facing the problem of Emerson quality flowmeter displaying fault code A110, which indicates frequency output saturation, we should first investigate and solve it from the following aspects. Firstly, check if the Frequency Output Scaling Method parameter is set correctly. This involves the calibration method of frequency output, ensuring that it is consistent with the requirements of the system, which is a key step in solving this problem. Secondly, based on the values reported by the flow meter, carefully evaluate the current process status. This includes whether the readings displayed by the flow meter are abnormal, as well as the overall operation of the process flow. Once again, conduct a thorough inspection of the process site. Ensure that there is no air res
