Output Signals

(1)

Analog: volumetric meter-eld rangeable linear 4-20 mA output signal (1200

ohms maximum loop resistance) selected by user for mass ow rate or

volumetric ow rate.

Communications: HART, MODBUS-RTU, RS485, BACnet MS/TP

Multiparameter Meter: Up to three eld rangeable linear 4-20 mA output

signals (1200 ohms maximum loop resistance) selected from the ve

parameters mass ow rate, volumetric ow rate, temperature, pressure and

density.

Pulse: pulse output for totalization is a 50-millisecond duration pulse

operating a solid-state relay capable of switching 40 VDC, 40 mA maximum.

Note: (1) All outputs are optically isolated and require external power for

operation.

Alarms Up to three programmable solid-state relays for high, low or window alarms

capable of switching 40 VDC, 40 mA maximum.

Totalizer Based on user-determined ow units, six signicant gures in scientic

notation. Total stored in non-volatile memory.
