ORIPAC MODEL 5300

About the Oripac Model 5300 Dimension Sheet Tech Support Sheet
Part No. Reference System Specification Sheet Installation Instructions
MODEL 5300 INSTALLATION INSTRUCTIONS
General: Many of the installation problems associated with standard orifice plates have been eliminated by the use of the Oripac. Simply follow these instructions for an accurate and reliable meter.

Pipe Requirements: Upstream and downstream pipe requirements are contingent upon two factors: (a) Beta Ratio:-ratio of the orifice bore "b" divided by the inlet bore (pipe l.D.)  (b) The type of fitting or disturbance upstream of the Oripac. For most applications, 10 pipe dia. upstream & 5 dia. downstream are sufficient. (5 pipe dia. up and 2 dia. down are acceptable for non-critical application.) Refer to additional piping requirement sheet for specific scenarios.

Installation Tips: (a) If possible, do not install a valve upstream if it is going to be throttled. Install on the downstream a minimum of 6 diameters from the Oripac. (b) The use of straightening vanes is not necessary for most applications.

Actual Installation: (a) Insert bolts through bottom half of the flange bolt circle. (b) Slide Oripac between flanges (make sure arrow on Oripac faces in the direction of flow) (c) Make sure pressure connections are properly positioned.  Oripac can be installed vertically or horizontally. For horizontal liquid lines, install the Oripac with the connections on or under the horizontal center line. For horizontal air or gas lines, install with the connections on or above the horizontal center line. They should also be correctly oriented so as to not be blocked by bolts when remainder of bolts are inserted: (d) Add rest of bolts and nuts leaving all bolts loose so Oripac is free to move. (e) If necessary, the Oripac can be centered using a steel ruler to measure the total side to side movement and set Oripac at half way point all around. (f) Lubricate & tighten bolts diametrically alternating to recommend flange torque. (g) Check to insure the Oripac is installed with the arrow facing in the same direction as flow.

CAUTION:
On Model 4150 only, do
not remove pressure fittings or nipples
as they are permanently attached.
Use wrench to steady pressure
fittings/nipples when installing additional
fittings.


*Bolts should be 1.25” longer than standard make up flange bolts.

Connection Kit:
Includes 1/4" and 3/16" SS Extension Nipples with 1/4" and 3/16" SS Full Port Ball Valves - FNPT Ends.
