. A sensor located 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 .
7 .) Install the 2 inch NPT adapter provided, using a thread sealant to prevent leakage . Tighten as necessary . Badger Meter insert style flow sensors are calibrated with the sensor inserted 1-1/2 inches (38 mm) into the pipe flow .
Hot Tap Installation for 225BR, 226BR, and 226SS Alignment of Flow Sensor 1 . Loosen the positioning collar set screws with a 3/32 inch Allen wrench . Place the alignment rod through the sight holes in the flow sensor . See Figure 2 .
HOT TAP INSTALLATION FOR 225BR, 226BR, AND 226SS Badger Meter Series 200 hot tap style liquid flow sensors are designed for use in cases where pipelines will be in continuous service, and depressurizing or draining the system for installation or service is not practical .
(48 mm) hole . 3 . Install the Badger Meter isolation valve and nipple onto the fitting using pipe thread sealant or Teflon® tape on all threads . 4 . Install the Badger Meter hex mounting adapter onto the valve assembly . Use pipe thread sealant on the adapter .

Hot Tap Installation for 225BR, 226BR, and 226SS Example: The sensor is installed in an 8 inch schedule 80 pipe, with a pipe wall thickness of 1/2 inch . If the overall sensor length is 16-3/8 inches and the H dimension is 10 inches, the D value is calculated as follows: D = Overall length −...

Hot Tap Installation for 225BR, 226BR, and 226SS 15 . Install the three lock nuts onto the threaded rods, tightening only the lock nut on the threaded rod with the preset hex/ jam nut . 16 . Then bring the two remaining lock nuts down until they just contact the positioning collar . Do not tighten at this time . 17 .
. 1 . Route the cable from the sensor to a Badger Meter flow monitor/transmitter . The cable can be extended up to 2000 feet, using 2-conductor shielded 20 AWG or larger stranded copper wire . Be sure to leave enough flexibility in the cable or conduit to allow for future service of the flow sensor, if necessary .
High Temperature Sensors 1 . Route a cable from the sensor to a Badger Meter flow monitor/transmitter . The cable can be extended up to 2000 feet, using 2-conductor shielded 20 AWG or larger stranded copper wire . Be sure to leave enough flexibility in the cable or conduit to allow for future service of sensor, if necessary .
CALIBRATION Badger Meter sensors use unique K and Offset numbers for calibration . These numbers are derived from calibration runs using NIST traceable instruments . Using both a K and an Offset number provides higher accuracy than using a K (pulse/gal) factor alone .

IMPELLER ASSEMBLY AND SHAFT REPLACEMENT If you are replacing an existing Badger Meter sensor and have already calibrated your flow monitor/transmitter, no calibration changes are necessary . For installation of a new flow monitor or for relocation of a sensor in a new pipe size, see the calibration instructions in this manual .
Troubleshooting TROUBLESHOOTING 1 . If the voltage at the sensor input is less than 7V DC in a no flow situation, disconnect the sensor from the barrier strip and measure the voltage again at the sensor input terminals of the barrier strip . It should be between 8…20V DC . If the voltage at the sensor input is still below 7V DC or 3V DC, the problem may be with the monitor (hardware or programming) .
