3.3.3 Insertion depth measurement calculation for the RIM10-700
Use the following equation to calculate the insertion depth for the RIM10-700:
B = C – I – E – Wt
Where:
B = Installed dimension to be set on the flowmeter.
C = For G6 rotor 362 mm (14.25")
For L1 and G1 to G5 rotors 368 mm (14.50")
I = For pipe sizes less than 300 mm (12"), inside pipe diameter ÷ 2
For pipe sizes 300 mm (12") and larger, inside pipe diameter ÷ 4
E = Distance from the raised face of the flange or top of the screwed fitting to the outside
pipewall.
Wt = Thickness of the pipe wall. The disk cut-out or 'coupon' from the tapping procedure
can be measured, or this number can also be obtained from a piping handbook.
Example:
An RIM10-700 with a G6 rotor is to be installed on a 300 mm (12") Schedule 40 pipe. The
following measurements have been obtained:
C = 362 mm
(14.25")
I = 303.2 ÷ 4 = 75.8 mm
(11.938" ÷ 4 = 2.98)
E = 114.3 mm
(4.5")
Wt = 10.3 mm
(0.406" 12" Schedule 40)
B = C-I-E-Wt = 362 - 75.8 - 114.3 - 10.3 = 161.6 mm (14.25" - 2.98" - 4.5" - 0.406" = 6.364")
Manually insert the stem into the pipe until the calculated insertion depth is obtained. Align
the rotor by using the orientation levers so that the flow direction arrow is parallel to the pipe
and pointing downstream.
Lock the stem in position by tightening the Swagelok
®
fitting. Verify insertion depth prior
to final tightening of the fitting. When the fitting has been tightened, the stem position
becomes permanent and cannot be changed.
