First, the fluctuation is relatively large. The reasons for the relatively large fluctuations in traffic can be considered from the following aspects:
1. Is the water source a pulsating flow?
(1) Generally, pumping raw materials is used. If the flow installation position is close to the pump, it is easy to generate pulsating flow, which causes the flow fluctuation to be relatively large. At this time, the solution increases the straight pipe distance between the pump and the flow meter. Stabilize the flow.
(2) The installation position of the flowmeter is too close to the position of the valve or the elbow. When the raw material passes through the valve or the bent pipe part, the flow fluctuates. At this point, it should be away from the valve and elbow position to ensure a certain straight pipe section
2. Is there any interference source such as motor, inverter, or strong power near the flowmeter? Solution: Ground the meter meter or add a filter capacitor. If it can't be solved, it should be away from the source of interference.
Second, the flowmeter has no display flow solution
(1) First check if there is any problem with the line, such as the signal line falling off, there is a broken line, and so on.
(2) Separate the sensor from the signal amplifier, connect the signal amplifier to the meter, and use the ferrous metal to move back and forth at a distance of 2~3mm from the bottom of the amplifier that takes the signal. If the meter has a display, the display part has no problem. Remove the flow sensor from the pipe and check if the flowmeter impeller is entangled or the impeller is damaged.
Third, the flow meter shows a small flow, and the actual flow is relatively large. The general cause of this problem is that the impeller rotates not smoothly or the blade breaks. Remove the flow from the pipe and check if the flowmeter is entangled or damaged.
Fourth, the flowmeter display error is relatively large
(1) First check the flow sensor coefficient, ie the K value and other parameters of the instrument are set correctly.
(2) If the customer has conditions, use the electronic scale to perform actual calibration and calibration.
The turbine flow sensor is composed of a display instrument. The sensor has the characteristics of high precision, good repeatability, long life and simple operation. It can be widely used in petroleum, chemical, metallurgy, papermaking and other industries to measure the volumetric instantaneous flow rate and volume of liquid.
