The vortex flowmeter utilizes the turbine rotor to rotate and measure the flow rate, displaying zero may be due to sensor damage, pipe clogging, power supply failure or signal line failure.
1. Working principle of vortex flowmeter
Vortex flowmeter is a flowmeter that measures the volume flow of fluid in a pipeline. Its working principle is to use the turbine rotor to rotate under the action of fluid flow, and calculate the flow rate and flow rate through the pulse signal generated by the sensor. This flowmeter has the advantages of wide measurement range, high precision and good stability, and is widely used in various industrial fields.
2. Reasons why the vortex flowmeter displays zero
1. Sensor damage: The vortex flowmeter sensor is the core component of the instrument, and its damage causes the vortex flowmeter to display Common causes of zero.
2. Pipe blockage: If there are impurities, sediments and other substances in the pipeline, it will cause the pipeline to be blocked and affect the accuracy of the vortex flowmeter measurement.
3. Power failure: Abnormal power supply or insufficient power supply of the vortex flowmeter may cause it to fail to work properly.
4. Signal line failure: Poor connection or open circuit of the signal line of the vortex flowmeter will also cause it to display zero.
3. Solution to the vortex flowmeter showing zero
1. Check the sensor: Maintain the vortex flowmeter, check whether the sensor is damaged or worn, and replace it in time.
2. Clean the pipes: Maintain and clean the pipes regularly to avoid internal blockage of the pipes.
3. Check the power supply: Check the power supply line of the vortex flowmeter and confirm that the power supply is normal.
4. Verify the signal line: Regularly check whether the signal line is well connected. If the signal line is broken, replace it in time.
