Liquid turbine flowmeter is a commonly used flow measurement instrument, which has the obvious advantages of compact structure, clear and intuitive reading, high reliability, no external power interference, lightning strike resistance, and low cost. Turbine flowmeters will have certain failures during use. The user must master the troubleshooting methods. Today Xiao Bian came to give you specific details on the common faults and treatment methods of turbine flowmeters, hoping to help everyone.

Turbine flowmeter common faults and treatment methods:
First, traffic fluctuations are relatively large The causes of the relatively large fluctuations in traffic flow can be considered from the following aspects:
1. Whether the water source is pulsating
(1) In general, pumping raw materials, if the flow installation position is relatively close to the pump, it is easy to produce pulsating flow, which causes a relatively large flow fluctuations. At this time, the solution is to increase the straight pipeline distance between the pump and the flow meter. Make the flow stable.
(2) The installation position of the flowmeter is too close to the position of the valve or elbow pipe. When the raw material passes through the valve or the elbow pipe, the flow rate will fluctuate. At this point, it should be far away from the position of the valve and the elbow to ensure a certain straight pipe section before and after
2. Is there an interference source such as a motor, frequency converter, or strong electric power near the flowmeter? Solution: flow meter grounding, or filter capacitor. If you cannot solve it, you should stay away from sources of interference.
Second, the flow meter shows no solution
(1) First check if there is any problem with the line, such as the signal line falling off, disconnection, etc.
(2) Separate the sensor from the signal amplifier, connect the signal amplifier to the meter, and use iron metal to move the distance from the bottom of the signal amplifier at a distance of 2~3mm. If the meter has a display, then the display part is no problem. Please remove the flow sensor from the pipe and check whether the flowmeter impeller is entangled or the impeller is broken.
Third, the flow meter shows that the flow rate is small, and the actual flow rate is relatively large. The reason for this problem generally is that the rotation of the impeller is not slippery or the blades are broken. Remove the flow from the pipe and check that the flow meter is tangled or damaged.
Fourth, the flowmeter display error is relatively large
(1) First check whether the flow sensor coefficient, ie K value, and Other parameters of the instrument are set correctly.
(2) Actual calibration and calibration with electronic scales are performed under the condition of the customer.
Turbine flow sensor and display instrument supporting components. The sensor has the characteristics of high precision, good repeatability, long life, and simple operation. Can be widely used in petroleum, chemical, metallurgy, papermaking and other industries to measure the volume of liquid instantaneous flow and total volume.
