Badger Meter Vortex Meters - Manual (Page 17)

Form No. 09-VRX-UM-00007 15
Diaphragm or piston pumps may not be used. Do not use Teflon tape or any kind of pipe dope
when piping.
The simple appearance of the flow meter may tempt an installer to handle it as an ordinary nipple. Re-
member, it is a precision electronic instrument. Treat it with care.
Do not use excessive force. Mating fittings (FNPT) and flanges should be screwed into meter hand tight;
then tighten an additional ½ to ¾ turn.
Always use two wrenches when turning the flow meter into a fitting, one across the flats on the flow
meter end, close to the fitting, and one on the fitting.
Do not use tools inside the flow meter, as this may damage the vortex sensor, and invalidate the war-
ranty.
The flow meter may be mounted in any orientation. Three holes, tapped ¼-20 UNC-2B, .375-inch deep,
on ¾” centers are provided on the ¾ inch and smaller flow meters. These holes may be used (at the user’s
discretion) to provide support for the flow meter should pipe supports not be practical.
