What should I do if the output value of the electromagnetic flowmeter often fluctuates? The fluctuation of the output value of an electromagnetic flowmeter can affect the measurement effect. Generally speaking, the reason for this situation is caused by the influence of the measuring medium or external environment. In some production environments, due to the large vibration of the measuring pipeline or liquid, the circuit board of the flowmeter may become loose, which can also cause fluctuations in the output value. Kewill, a technical engineer, suggests that the first step is to modify the finger answer to destroyed; Confirm whether it is due to process operation reasons, the fluid does indeed experience pulsation. At this time, the flowmeter only reflects the flow condition truthfully, and the fault can be eliminated by itself after the pulsation ends. secondly; Electromagnetic interference caused by external stray currents, etc. Check whether there are large electrical appliances or welding equipment working in the instrument operating environment, and confirm that the instrument is grounded and the operating environment is good. Again, when the pipeline is not filled with liquid or when there are bubbles in the liquid, both are caused by process reasons. At this point, the process personnel can be requested to confirm that the output value can be restored to normal after the liquid tube is full or the bubbles are flat. In addition, the transmitter circuit board is a plug-in structure, which often causes the power board of the flowmeter to loosen due to the large vibration of the pipeline or liquid measured on site. If it is loose, the flowmeter can be disassembled and the circuit board can be re fixed.

2. Electromagnetic flowmeter, when the flow rate is stable, displays a gradual decrease in flow rate, and it also remains the same after being replaced with a turbine flowmeter 1. Firstly, check the position of the pipeline. 2. Whether the pump is filled with water is similar to your fault. 3. Whether the control cable of the pump is on the same bridge as the signal line of the flow meter. 4. Whether the signal line carrying the cable is a shielded cable solution. If it is a pipeline problem, change the pipeline. If the pump power is not enough, replace the water pump. If it is a signal interference, add a signal isolator to remove the detection element. Other problems should be resolved. 3. Boiler steam flow meter, consult experts to judge the problem. Water evaporates into steam, and its expansion ratio under normal pressure is 1860 times. Under different pressures, its density also changes accordingly. Below are the answers to your questions one by one:

1. The steam flowmeter consists of two broad trace parts. The first part is the sensor part, which is commonly known as the flowmeter. The equipment installed on the pipeline includes vortex street, orifice plate, Annubar, pulse and other forms. The second part is the integrated computing device, which includes functions such as calculation and display. It calculates the instantaneous flow rate and cumulative flow rate based on the pulse signal transmitted by the sensor, combined with the pressure signal and positive signal, and also has a recording function. This pressure signal is actually the density corresponding value that has already been set. So, you dont have to worry about density changes affecting accuracy.
