Why does the flowmeter display unstable and fluctuating readings, and how to resolve this issue?

This may be caused by excessive vibration of the pipe where the ultrasonic flow sensor is installed, or the presence of flow-altering devices (e.g., the flowmeter is installed downstream of control valves, pumps, or orifices). The solution is to reinstall the flow sensor away from vibration sources or move it upstream of the flow-altering devices. This ensures a stable measurement environment and reduces the interference of external factors on ultrasonic signals, thereby stabilizing the readings.
