Equipment Configuration:vortex flowmeter

The main reason for the large fluctuation of vortex flowmeter.

Project Overview

  Inconsistent pipes or diameters: Inconsistencies or significant differences in pipes or diameters can cause significant fluctuations in measurement data.

  Pipeline vibration: Pipeline vibration can cause measurement data to deviate.

  Medium changes: Changes in pressure, density, and temperature of the medium can cause differences in measurement data.

  Signal interference: Signal interference can cause significant fluctuations in flow meter measurement data.

  Inaccurate readings: Inaccurate readings of vortex flowmeters can lead to significant fluctuations.

  Dirt: Vortex flow meters may experience varying degrees of dirt after prolonged use, affecting the accuracy of readings.

  Specific handling methods for different reasons

  Calibration of vortex flowmeter: Compare with standard flowmeter to ensure accuracy.

  Cleaning vortex flowmeter: Regularly clean the flowmeter to reduce reading fluctuations.

  Replacement of accessories: If the turbine blades are damaged or worn excessively, the turbine can be replaced; If accessories such as the core drum and photoelectric plug malfunction, they also need to be replaced.

  Avoid vibration: Avoid installing flow meters near vibration sources and install anti vibration devices.

  Eliminate interference: Stay away from interference sources and add shielding devices.

  Adjust pipeline and medium conditions: Install drainage or venting devices to ensure consistent temperature and prevent gasification or liquefaction. ‌
