【Typical Issues in Flow Meter Installation 013】Ultrasonic flow meters should be kept at a sufficient distance from interference sources such as valves, pumps, high-voltage electricity, and frequency converters
Thread Content
Ultrasonic flowmeters are also relatively common types of flowmeters. Their installation is the simplest and most convenient among all flowmeter installations: one only needs to select an appropriate measurement point, enter the pipeline parameters at that point into the flowmeter, and then fix the probe to the pipeline. The installation of ultrasonic flowmeters follows these 3 main principles: 1. Select a pipe section that is filled with fluid, has uniform and dense material, and facilitates the transmission of ultrasonic waves, such as a vertical or horizontal pipe section. 2. The installation location should be in a straight pipe section with a length of more than 10 times the diameter of the straight pipe upstream, and more than 5 times that diameter downstream, and such a section should contain no valves, elbows, diameter changes, etc.; the installation point must be far enough away from sources of interference such as valves, pumps, high-voltage electricity, and frequency converters. 3. Avoid installing at the highest point of the piping system or on vertical pipes with a free outlet. 4. For pipes with open or partially filled sections, the flow meter should be installed at the U-shaped section.
