The general guidelines suggested by manufacturers of turbine flow meters are 15-20 straight pipe diameters (inclusive of the strainer) straight pipe runs 

When a designer is planning a piping layout with an Orifice Plate flow meter, the traditional rule of thumb is between 10 and 15 pipe diameters 

The flow sensor – type, turndown and straight-run pipe requirements Upstream or downstream the PRV Station. • Straight-run pipe Straight-run length.

Meters often require a specified amount of straight run upstream and downstream to deliver these accuracies—sometimes five to 10 or more pipe 

1) Downstream length shown here includes plate thickness of 0.162-in. (4.11 mm). (2) B.D is diameter of the precision bored portion of the upstream and 

There also is no requirement for upstream and downstream length. A problem is if there is a process disturbance at the same resonant frequency as the tubes and drive coils in the meter. Coriolis meters have a higher turndown ratio than other flow measurement technologies. Dan discussed Ultrasonic flow measurement technology.

elbow and the upstream side of magnetic flow meters was completed in this research. installed only three diameters downstream of the elbow.

Jan 05,  · 18" diameter duct. 180-inch-long straight section, upstream end open to atmosphere, downstream end connected to flow meter. Downstream of the meter, there is a 90-inch-long straight section, and then there's a blower, pulling air through the duct. I'm wondering what sorts of obstructions can be tolerated near the inlet end of this system.

Typical recommendations suggest 35 straight pipe diameters upstream and 5 straight pipe diameters downstream. If you don't have sufficient upstream straight run, some manufacturers allow for K factor corrections that could reduce this requirement.

Due to the nature of the measuring probe protruding into the media and creating its own obstacle of sorts, the straight run requirements for insertion flow meters is highUsually, 20x to 50X upstream straight run requirement recommended
