Analysis of Precession Vortex Flowmeter Common Faults and Solutions:
Precession vortex flowmeter is mainly used to measure the flow of gas and liquid. It can automatically and accurately detect the temperature, pressure and flow value of the medium, and directly display the cumulative volume of the medium under the standard state. It can display various parameters on the spot and can transmit a variety of signals far. It adopts advanced technology, realizes intelligent processing of multiple functions and adopts dual sensors, new signal processing amplifiers and unique filtering technology, effectively eliminating interference signals generated by pressure fluctuations and pipeline vibration, and greatly improving the flowmeter. The anti-jamming capability gives it excellent stability and accuracy.
　　
Spin-in vortex flowmeter fault phenomenon and treatment
　　
1, no output signal
　　
Precession into the vortex meter Cause: The pipe has no medium or flow rate below the lower limit; check the connection of the power supply and output line; check the preamplifier circuit for damage; check the input amplifier circuit for damage.
　　
Treatment method: Increase the flow of the medium to meet the flow requirements; correct wiring; replace the preamplifier; replace the damaged components of the output amplifier circuit.
　　
2, flow meter output
　　
Precession into the vortex flow meter Cause: Flowmeter is badly grounded or is a strong electrical ground and other ground wire interference; the amplifier sensitivity is too high or self-excited; the piezoelectric sensor and the preamplifier are in poor contact or open circuit; the power supply is unstable, filtering Bad and other electrical interference. 〔2〕
　　
Precession eddy vortex flowmeter processing method: Correctly connect the ground wire to eliminate interference; replace the preamplifier; check the circuit to make it normal; repair or replace the power supply and eliminate interference.
　　
3, flow meter display instability
　　
Precession into the vortex meter Cause: The amplifier sensitivity is too high or too low, there is a phenomenon of leakage pulse; the depth position of the piezoelectric sensor is not adjusted properly; the installation of the flowmeter has unstable vibration or electrical interference; bad grounding; incorrect installation location Before the flow meter has a turn. Processing method: Replace the preamplifier; readjust the depth position of the piezoelectric sensor; eliminate unstable vibration and interference; check the grounding circuit to make it normal; change the mounting position.
4. Accumulated flow indication display does not match actual flow
　　
Reason: Flowmeter meter coefficient input is not normal; user's normal flow rate is lower or higher than the normal flow range of the selected flowmeter; flowmeter itself is very bad; fluid cavitation phenomenon; pipeline boring number is not in the range of 2×104～7×106 Inside.
　　
Precession vortex flowmeter processing method: re-calibration, use the function button to set the adjustment, make it correct; adjust the flow of the pipeline to make it normal; re-calibration; reduce the pressure loss of the fluid to avoid air bubbles.
　　
5, switch display error
　　
Precession into the vortex meter Cause: Check the wiring is correct; check the switch button contact is good; check the display wiring is good; confirm whether the display.
　　
Spin-in vortex flowmeter processing method: correct wiring; replace the button; correctly connect the display line; replace the display.
