WebJul 13, 2024 · Typically, flowmeter manufacturer’s specify a minimum of 10 to 15 diameters of straight pipe. This means that for a 4″ diameter pipe, you would need 10 x 4 = 40″ of straight pipe, or for a 2″ pipe you would need 10 x 2 = 20″ of straight pipe. However, for more severe flow distortions, you may require more.
