Badger Meter Irrigation Sensors - 1/2 and larger" - Manual (Page 5)

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 assembly, remove the sensor sleeve to prevent heat damage
to the O-rings and plastic parts.
2. Apply pipe compound over the fi rst 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 additional 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 fl ow arrow on sensor with direction of fl ow.
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.
Mechanical Installation for 250BR
Install with flow label pointing in the direction of flow (downstream).
To install the sensor tee
1. Note intended direction of fl ow as indicated by arrows on the cast bronze tee. There must be free, unrestricted pipe
for at least 10 diameters upstream and 5 diameters downstream of the tee.
2. Apply pipe compound over the fi rst 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 additional 1 1/2 turns.
To install sensor in tee
1. Apply a small amount of silicone grease to O-rings on sensor insert and chamfer on inside lip of tee. Clean off any
grease which could be deposited on the impeller.
2. Align fl ow arrow on sensor with direction of fl ow.
3. Carefully press sensor straight into tee.
Impeller may strike the sides of venturi cavity in tee if misaligned, causing damage to impeller or shaft.
4. Install clevis pin through the tee, sensor and conduit cap, and install split ring.
5. Before pressurizing pipe, verify that:
• All threaded connections are tight.
• The flow direction arrows on the tee and sensor are aligned with the flow direction.
• The clevis pin and cotter ring are installed.
