Hardware Fault Handling of Mass Flow Meters - Focus on Microfluidic Control Technology
Mass flow meter is one of our main products. Today, Xiaobian will introduce you to the knowledge of hardware faults in mass flowmeters: First, if the error is too large, the totalizer display does not light or does not add value, the display blank position and other phenomena, the reason: 1. Installation is not standardized, which can directly lead to zero drift of the flowmeter. For example, the mass flowmeter is installed near the pump outlet, the sensor support strength is not enough, the connection flange is improperly welded to generate stress signals, and the cable is subject to electromagnetic interference. 2. Wiring problem 2. If the display does not light, check the power supply connection of the totalizer. If the fuse is burnt, confirm the input voltage and the standard voltage, and the AC and DC forms are consistent. If the totalizer does not increase with the flow rate, check the totalizer wiring. If the accumulator is equipped with a forward/reverse procedure, check the flowmeter wiring. If the flowmeter is not wired correctly, the totalizer will be reversed. Does not increment when flowing. 1. Process media changes 3. If there is air entrainment, gasification or two-phase flow in the measuring medium, the transmitter will display an alarm. In severe cases, the sensor will stop working. 1. The transmitter has failed. 2. The sensor is invalid. 3. Pipe cleaning problems.
