General information
5.1.1
Design and function
The device consists of a transducer (sensor) and a transmitter with a display. The transducer operates
according to Faraday's law of induction.
The flowmeter is equipped with an analog output (current output AO1, 4 to 20 mA), a digital output (tran-
sistor output DO1, basic setting: pulse output), and two counters.
It also has two digital outputs (relay outputs DO2 and DO3) and one digital input (DI1).
The device operates as a three-wire system and requires a voltage supply between DC 18 to 36 V.
The electrical connection takes the form of two cable fittings (M20 × 1.5) connected to the electronic
board's terminal strips inside the transmitter.

Areas of application
This flowmeter is intended solely for the purpose of measuring the flow rate of liquids (media or mea-
sured media),
see chapter 2 "Intended use", page 8.
The adjustable transistor output and the two relay outputs enable the device to switch a solenoid valve
or activate an alarm. The current output (4 to 20 mA) allows a control circuit to be created.
The digital input enables a function to be triggered remotely.
