Badger Meter Vortex Meters - Manual (Page 20)

18 Form No. 09-VRX-UM-00007
Diaphragm or piston pumps may not be used. Do not use Teflon tape or any kind of pipe dope when pip-
ing. For flanged meters, do not allow gaskets to protrude into the flow stream.
The following steps will insure proper installation and operation.
1) A uniform flow profile is required to assure proper vortex shedding. This requires a non-pulsating
flow along with the proper length of straight pipe run before and after the transmitter. Figures
2,3,4 and 4 shows the proper piping requirements and dimensions.
FLANGE SIZE RECOMMENDED TORQUE
½ -1½” 10-15 ft. Ibs.
2-3” 20-30 ft. Ibs.
2) Flanges are to be spaced to accommodate the width of the flow body. Dimensions are listed on
page 20.
3) Align the flow body centered with respect to flanges and gaskets, insert threaded rods, retaining
nuts and lock washers.
4) Install all retaining nuts hand tight, and then uniformly tighten the nuts in an alternating se-
quence, diametrically opposed to each other. Uniform stress across the flange will prevent leak-
age at the gasket. Torque ratings are listed below.
5) The use of grounding rings is recommended when metal pipes are used in conjunction with this
meter. See figure 13
