Outputs
Analog Output
The Analog Output shows the currently measured ow rate.
The Analog Output is a 4 - 20 mA current loop (the end user must supply power to
the unit).
The Analog Output is programmable for forward and reverse ow (see Operation
Manual for more details).
The 20mA point is programmable per customer request (To any ow lower than the
max ow of the meter).
Digital (pulse) Output
The Digital (pulse) Output is an open drain transistor output that provides pulse per
quantity with these options:
1. Two scaled forward, reverse or net mode pulses
2. One scaled forward, reverse or net mode pulse and one alarm frequency output
3. Measuring units of the output can be programmed dierent than displayed units
Pulse resolution will be shown on the display for each pulse separately
Dry Contact Output
The Dry Contact Output is a dual relay output that provides pulse per quantity with
these options:
1. Two scaled forward, reverse or net mode pulses
2. Measuring units of the output can be programmed dierent than displayed units
Pulse resolution will be shown on the display for each pulse separately
Onsite power supply of 12-24 VDC is needed.
Encoder Output
The Encoder Output is a serial communication collector utilizing UI1203 or UI1204
communication protocol. (Sensus protocol) Pulse output included.
Modbus Protocol Output
The Modbus Protocol Output has the following available functions:
1. Alarms (battery, empty pipe)
2. AMR serial number
3. Real Time Clock (RTC)
4. Volume units
5. Flow rate units
6. Current ow
7. Flow direction
8. Forward and reverse volumes
9. Flow and volume resolution
Output Extension Cable
5m extension cable for installation in pits and vaults
