Caution:

Follow these instructions to avoid 

failure.

Danger:

Wear eye protection when 

installing or removing flowmeter.

1.

 Polysulfone and other exotic plastics 

cannot tolerate PVC Glue and /or pipe dope.  
even fumes can cause crazing.

2. 

If you are installing your flowmeter to 

a glued pipe configuration, install 
flowmeter after all glued fittings are dried 
and lines are purged of all fumes. 

Use Teflon® tape (or similar) for the 
flowmeters threaded adapters.

Hand tighten union nuts.  

No wrenches.

3. 

Wall, floor, and ceiling mounts are to 

be carefully aligned and sturdy.  Wall, 
floor, and ceiling supports are recom-
mended as needed. 

4.

 Valves - Avoid a system that will impose a sudden burst of flow to the meter.  Such 

a burst will cause the float to impact the float stop with destructive force.  Magnet, 
solenoid, or other quick opening valves cannot be used unless meter is protected 
against sudden bursts of flow. 

5.

 The maximum working pressure should not exceed 150 psi at ambient 

temperature.
