In some gas measurement applications the sensor size could be one or more pipe sizes smaller than the upstream or downstream piping, requiring pipe reducers and expanders. Excessive lengths of small diameter pipe or abrupt flow diameter reductions such as tees, short radius elbows, etc., can adversely affect pressure drop.

Straight Pipe Requirements — Ultrasonic Flowmeters l SoundWater

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. How much straight pipe do you need?

Upstream and Downstream Flow Straight Pipe Requirements-Flowmeter

The general rule of thumb for straight piping is a five-diameter length of piping upstream and three diameters downstream from the meter (measured from the center of the tube).
