General
The accuracy of flow measurement for all flow measuring
devices is highly dependent on proper location of the
sensor in the piping system. Irregular flow velocity
profiles caused by valves, fittings, pipe bends, etc. can
lead to inaccurate overall flow rate indications even
though local flow velocity measurement may be accurate.
A sensor located in the pipe where it can be affected by
air bubbles, floating debris, or sediment may not achieve
full accuracy and could be damaged. Badger Meter flow
sensors are designed to operate reliably under adverse
conditions, but the following recommendations should be
followed to ensure maximum system accuracy:

1) Choose a location along the pipe where 10 pipe diam-

eters upstream and 5 pipe diameters downstream of
the sensor provide no flow disturbance. Pipe bends,
valves, other fittings, pipe enlargements and reduc-
tions should not be present in this length of pipe.

2) The preferred location for the sensor around the

circumference of a horizontal pipe is on top. If trapped
air or debris will interfere, then the sensor should be
located further around the pipe from the top but not
more than 45 degrees from top dead center. The
sensor should never be located at the bottom of the

pipe, as sediment may collect there. Locations
off top dead center cause the impeller friction to
increase, which may affect performance at low
flow rates. Any circumferential location is correct
for installation in vertical pipes. Rising flow
preferred to reduce effects of any trapped air.

These tee-type sensors have a factory set inser-
tion depth and alignment.
Warning: do not disturb the position of
thread hex adapter or the lower two nuts on
the threaded rods

of the hex

adapter. This could lead to inaccurate calibra-
tion and faulty reading of the flow rate.
Remove sleeve assembly by removing the top
7/16" nuts only. Pull the sleeve assembly straight
out of the mounting adaptor.

To install the sensor tee
1)

There must be free, unrestricted pipe for

at least 10 diameters upstream and 5 diameters
downstream of the tee. note: If soldering of
threaded adapters is to be done near the as-
sembly, remove the sensor sleeve to prevent
heat damage to O-rings and plastic parts.
2)

Apply pipe compound over the first 3 or 4

threads of the mating pipe.
3)

Thread the pipe into the sensor tee until

hand tight.
4)

Tighten the pipe, using a wrench, an ad-

ditional 1 1/2 turns.

To install sensor in tee
1) Apply a small amount of silicone grease to O-rings on

sensor sleeve assembly and chamfer on inside lip of
tee. Clean off any grease which could be deposited
on the impeller.

2) Align flow arrow on sensor with direction of flow.
3) Carefully press sleeve straight into hex mounting

adaptor.

4) Install 7/16 lock nuts on threaded rod, tighten, do not

move bottom nuts as they set sensor depth.

5) Before pressurizing pipe, verify that:

• All threaded connections are tight.

• The flow direction arrow on sensor is aligned with flow

direction.

• The 7/16 nuts are re-installed on the threaded rods

above the metal collar.
