flow meters

In the installation of magnetic flow meters (also known as electromagnetic flow meters ), " 10D and 5D " refer to the required straight pipe lengths upstream and downstream from the flow meter. 'D' represents the nominal diameter of the pipe.   *    10D: This means the straight pipe section upstream (before the fluid enters the flow meter) should be at least 10 times the pipe diameter. *    5D: This means the straight pipe section downstream (after the fluid exits the flow meter) should be at least 5 times the pipe diameter.   For example, if you are installing a magmeter on a 100mm diameter pipe , you would typically need a 1-meter straight pipe before the flow meter and a 0.5-meter straight pipe after it.   Why is Providing Adequate Straight Pipe Sections Crucial? The primary purpose of ensuring sufficient straight pipe runs is to guarantee measurement accuracy .   Flow meters measure the rate of fluid flow based on the principl...
