FLOW
Installation: To prevent debris from entering the meter, install the flowmeter
downstream from the filter if possible with at least the minimum straight pipe
dimensions called for in the above drawing. Drill the pitot tube hole in the top (12
o'clock position) of the horizontal pipe. Carefully remove all burrs. Insert the pitot
tube, with the gasket in place, into the drilled hole. Tighten the clamps alternately,
a little at a time. Make certain the flow direction is towards the pitot tube opening.
Examples:
WRONG
Not horizontal
within 2 degrees
Flowmeter size
1" thru 4"
6" thru 8"
Troubleshooting: Should the meter fail to read, make certain the openings in the
front and rear of the pitot tube are not clogged, that the pitot tube opening faces
the direction of the flow, and that you have installed the meter on the correct IPS
(ASTM-D-1785) type and size pipe. Note that the top of the float is the largest
diameter.
Accuracy = +/- 5% (L2), +/- 10% (L3)
Max Temperature = 190°F / 87.7°C
Maximum Pressure = 75 psi (5.2 bar)
Headloss = Maximum 1 psi across all pipe sizes
Note: Pressure and temperature limits are inversely proportional
