THEORY OF OPERATION
The ORION RF receiver can be located up to 500 feet away from the RF transmitter and must be powered with
12…24V AC/DC. A BNC connector is provided on the RF receiver to accept a 50 Ohm, half-wave antenna.
There are two red LEDs on the receiver.
• The“RF RCV” LED in the middle of the unit flashes each time it receives an updated total from the RF transmitter,
approximately every four seconds.
• The“OUTPUT” LED flashes each time an output pulse is generated by the receiver.
After each update, the RF receiver compares this updated total with the last one received. The difference is the total volume
in gallons that has passed through the sensor for the period in question. The RF receiver then generates a continuous burst
of output pulses with a duty cycle of 50%. These pulses can be scaled using the DIC Com Port and Badger Meter software to
represent the desired volume unit, number of volume units per pulse, and pulse width that best fit the application. Default
values for these settings are gallons, 10 gallons per pulse, and 50 milliseconds, respectively.
If the combination of volume units, volume units per pulse, and pulse width selected prevents the number of corresponding
output pulses from being generated in the 4…5 second update window, the RF receiver will simply delay the next update
until the pulse string has been completed.
Sensor Model 228PV200W-1231-000
Line Size 2 inches
Gallons per Integer Output from Transmitter 1 (default)
Volume Unit Selected in Receiver liters
Volume Units per Pulse Output from Receiver 10
Pulse Width 50 milliseconds
If 10 gallons pass through the sensor in a given 4 second window, 10 integer values are sent by the transmitter in the next
update, representing a volume of 10 gallons. The receiver, in turn, converts the 10 gallons into 37.8 liters and generates three
output pulses, representing a volume of 30 liters. Because partial counts exist in both the sensor and receiver, the remaining
7.8 liters are sent as part of the next update from the sensor.
OTE:N The Badger Meter Model A301W cable works with all Series 300 products. However, the older version of the cable
(A300) does not have sufficient bandwidth to work with this receiver.
