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 

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.

As a rule of thumb, most manufacturers recommend a minimum of “20 times the pipe diameter” downstream of a 90-degree bend. For some exceptions

User need to make sure the 10 pipe diameter lengths upstream and 5 pipe diameter lengths downstream. Installation Requirements. Straight pipe line of thermal 

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

For upstream and downstream lengths equal to one half the values shown, add 2 percent to the accuracy value. — Any flow conditioner shall be installed in the straight length between the primary element and the upstream distance, or the fitting closest to the element. The straight lengths between

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

1) Recommended lengths are guidelines based on ASME MFC-14M. (2) All straight lengths are expressed as multiples of the pipe in side diameter D and shall be measured from the upstream face o f the orifice plate to the disturbance.

NTS 15/05/06 D - PIPE INTERNAL DIAMETER FT - INCONEL VORTEX FLOW METER — DIRECTION OF FLOW NOTE - STRAIGHT PIPE LENGTH ON THE DOWNSTERAM SIDE TO BE 5 X PIPE DIAMETER MINIMUM TITLE : UPSTREAM DOWNSTREAM PIPING SHEET NO.

Normally you want to see a minimum 10 diameters upstream and 5 D downstream on a horizontal run. Might be OK as is, or even better to shift it left. A check valve might be a good idea to keep possible backflow from messing up the meter reading.

measurement bias, depending on the response of the flow meter to disturbed velocity profiles. Flow Conditioners A flow conditioner can be used to offset the effect of flow field disturbances caused by the upstream piping and to reduce the amount of straight pipe length required to allow a flow distortion to fully dissipate.

Up. 8. 9. 24. Down. 3. 3. 4. Note: 1. The straight runs shown above are conservative minimums. Longer upstream straight pipe lengths provide better accuracy 

The following diagrams describe the recommended minimum straightway lengths of some types of pipe. The straightway length should be as long as possible while the room is sufficient. Without the. consideration of other factors, the recommended minimum straightway lengths are: front upstream length: 20×DN. back downstream length: 5×DN.

B. Two pipe diameters (downstream) C. Flow direction Installations with reduced upstream and downstream straight runs are possible. In reduced straight run installations, the meter may not meet accuracy specifications. Reported flow rates will still be highly repeatable. 3.3 Flow direction. The sensor should be mounted so that the arrow points

Nearly all types and makes of ultrasonic flowmeters require some length of straight pipe upstream and downstream of the flowmeter itself.

In our technical support department, the primary installation question we get is: How much upstream and downstream straight run is required 

Cable type To transmitter Maximum length Micro Motion 9-wire 9739 MVD transmitter 1,000 ft (305 m) All other MVD transmitters 60 ft (18 m) Micro Motion 4-wire All 4-wire MVD transmitters — 1,000 ft (305 m) without Ex-approval — 500 ft (152 m) with IIC rated sensors — 1,000 ft (305 m) with IIB rated sensors

Oct 22,  · Straight pipe length. Take care to avoid eddy current generating components, such as various valves, elbows, bypasses, etc. Try to extend straight pipe sections upstream and downstream of the flow meter. Install a rectifier if necessary. Make sure the upstream of the flowmeter straight pipe is more than 5 DN (pipe diameter measurement), and the

Most manufacturers claim that their Coriolis flow meters are not adversely affected by installation effects. As such, they should not require large lengths of straight length pipe work upstream and/or downstream of the flow meter. However, compliance with the manufacturer’s guidance is necessary. This guidance can vary depending on flow tube
