Outputs
Analog Output

The Analog Output shows the currently measured flow 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 flow (see Operation Manual for more details).

The 20mA point is programmable per customer request (To any flow lower than the max flow 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 different 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 different than displayed units

Pulse resolution will be shown on the display for each pulse separately

Onsite power supply of 3-35 VDC is needed.

SSR (Solid State Relay) The SSR is a dual electronic 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 different than displayed units
Pulse resolution will be shown on the display for each pulse separately
Onsite power supply of 3-35 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 (barrety, empty pipe)2. AMR serial number

3. Real Time Clock (RTC)

4. Volume units

5. Flow rate units

6. Current flow

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
