The ultrasonic flowmeter installation location requirements are: it should be selected on a straight pipe section with stable water flow, no vortex and bubble interference, and at least 10 pipe diameters away from the upstream obstruction and 5 pipe diameters downstream.
1. Water flow stability: In order to obtain accurate flow readings, the ultrasonic flowmeter needs to be installed in a stable water flow location. This usually means that it is necessary to avoid installing it near elbows, tees, valves or other obstructions that may generate vortices. Otherwise, these vortices may cause ultrasonic signals to scatter, thus affecting the accuracy of the ultrasonic flowmeter.
2. Straight pipe section requirements: In order to ensure stable water flow, the ultrasonic flowmeter should be installed on a sufficiently long straight pipe. It is generally recommended to be at least 10 pipe diameters away from the upstream obstruction and 5 pipe diameters downstream. For example, if the pipe diameter is 100mm, the flowmeter should be at least 1m away from the upstream obstruction and at least 0.5m away from the downstream obstruction.
3. Avoid bubble interference: Bubbles will interfere with the ultrasonic signal, thus affecting the accuracy of the flowmeter. Therefore, when installing an ultrasonic flowmeter, avoid installing it in a location where bubbles may be generated, such as the outlet of a pump or in a pipe with a gas-liquid mixture.
4. Convenient maintenance and calibration: When selecting the installation location, factors that facilitate maintenance and calibration should also be considered. For example, the installation location should be easily accessible to personnel for regular inspection, cleaning, and calibration. At the same time, if possible, the installation location should be away from high temperature, high pressure, or other potential safety risk areas.
In short, when selecting the installation location of the ultrasonic flowmeter, factors such as water flow stability, straight pipe section requirements, avoiding bubble interference, and convenience of maintenance and calibration should be considered comprehensively. By reasonably selecting the installation location, it can be ensured that the ultrasonic flowmeter provides accurate and reliable flow measurement data, thereby providing strong support for the optimization and control of the process flow.
