1. Common faults and troubleshooting methods of vortex flowmeter "Knowledge sharing"

Vortex flowmeter faults can be divided into two categories: system faults and instrument faults. After a fault occurs, the system fault should be checked first, followed by the instrument fault. The specific common faults and their handling methods are as follows: System faults include installation and wiring errors, mismatched diameters, inconsistent flow ranges, vibration and electromagnetic interference effects, power supply problems, improper sensitivity adjustment, etc. After power on, there is fluid flow in the pipeline, but there is no signal output. Check if the instrument wiring is correct and if there is any disconnection. Incorrect wiring or disconnection can result in signal transmission failure, leading to a situation of no signal output. Check if the installation direction of the instrument is correct. The vortex flowmeter has specific installation direction requirements, and if the installation direction is incorrect, it will affect its detection of fluid signals. Check if the traffic is below the normal range. When the flow rate is too low, it may not generate enough signal to make the flowmeter output. There is no fluid flow in the power pipeline, but there is a signal output to check if the instrument is grounded and if interference is caused by poor grounding. Poor grounding can cause external interference signals to enter the flowmeter, resulting in false signal output. Check if there is strong mechanical vibration in the pipeline. Mechanical vibration may be mistaken by flow meters as a signal generated by fluid flow, resulting in the output of false signals. Check for strong electromagnetic interference i

n the environment, such as high-power electrical appliances or frequency converters. Strong electromagnetic interference can affect the normal operation of flow meters and generate false signals. Check if the sensitivity is too high, adjust the two potentiometers counterclockwise until there is no output. Excessive sensitivity can cause the flow meter to respond to small interference signals. Adjusting the potentiometer to reduce sensitivity can solve this problem. The flow rate of the fluid in the pipeline is stable and meets the flow requirements, but the output changes too much, and instability may be caused by poor grounding leading to interference. Poor grounding can cause external interference signals to continuously enter the flowmeter, making the output signal unstable. Possible interference caused by excessive pipeline vibration. Excessive pipeline vibration can cause significant fluctuations in the signal detected by the flowmeter, affecting the stability of the output. It may be due to low sensitivity and leakage triggering phenomenon. Increasing sensitivity is sufficient. Low sensitivity can make the flowmeter unable to accurately detect some fluid signals, resulting in leakage triggering and unstable output. The displayed flow rate does not match the actual flow rate, and the large error may be due to incorrect instrument parameter settings. Incorrect settings of instrument parameters such as range and coefficient can result in discrepancies between the displayed flow rate and the actual flow rate. It may be due to excessive measurement errors in temperature and pressure instruments. The flow measurement of vortex flowmeter is usually affected by temperature and pressure. If the temperature and pressure inst
