INSTALLATION
Step-By-Step
1
Prepare
To prevent debris from entering the
meter, install the flow meter downstream
from the filter if possible with at least the
minimum straight pipe dimensions.
*Minimum acceptable dimensions
2
Install
Drill the pitot tube hole in the top (12 O'clock position)
of the horizontal pipe or anywhere around vertical pipe.
Carefully remove all burrs. Insert the pitot tube, with
the gasket in place, into the drilled hole. Ensure the
flow direction is in the same direction of the flow arrow.
Tighten the clamps alternately, a little at a time.
3
Read
Avoid imposing a sudden burst of flow to the
meter. Solenoid valves may cause the float to
impact the top float stop with destructive force.
Always read float at top.
CARING
For your flow meters
Troubleshooting
Should the meter fail to read, ensure 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.
