Project Overview
What interference are ultrasonic flowmeters afraid of? First of all, we need to understand that an ultrasonic flowmeter is an instrument that measures volume flow by detecting the impact of liquid flow on an ultrasonic beam. In order to remove the interference effect and ensure the accuracy of the measurement results, when installing the ultrasonic flow meter, it is necessary to install, debug and check each ultrasonic flow meter to ensure good location selection, good installation and accurate measurement.
Interference factors that affect the measurement results of ultrasonic flow meters can be divided into internal interference & external interference.
1. Internal interference
1. Scaling on the inner wall of the pipeline affects the propagation of ultrasonic waves, causing errors in the flow meter. The solution is to use a cleaning device to remove the sediment in the pipe.
2. There are solid particles or bubbles in the liquid medium, causing errors in the flow meter. The solution can be to use a settler or gas detector to detect and remove it in time.
2. External interference
1. Pipe vibration causes flow meter errors. The solution can be to reduce pipeline vibration by installing compensators or strengthening pipeline supports.
2. Ambient temperature causes flow meter errors. The solution can be calibrated using temperature compensation method.
3. Noise causes errors in flow meters. The solution can be to use sound insulation measures to reduce noise interference.
4. Electromagnetic wave interference causes flow meter errors. The solution is to use filters to isolate spurious signals.
5. The large power fluctuation range causes flow meter errors. The solution is to calibrate the power supply regulator.
What interference are ultrasonic flowmeters afraid of? You can refer to the above points. Ultrasonic flow meter is a commonly used flow measurement instrument with various types, including insertion ultrasonic flow meter, pipe segment ultrasonic flow meter, clamp-on ultrasonic flow meter, portable ultrasonic flow meter, handheld ultrasonic flow meter and explosion-proof ultrasonic flow meter. Various types of calculations. When selecting and installing, you can contact the technical personnel of the ultrasonic flowmeter manufacturer and make a selection based on actual working conditions.
