Product versions

2.1. Flowmeter

Flowmeter with standard output signal

The device operates on a 2- or 3-wire system and needs a 12…36 V DC or a 115/230 V AC power supply.

The device is equipped with:

• an analogue output (4…20 mA current output)

• a digital output (pulse output) and

• two totalizers.

Some variants are also fitted with two fully configurable relay outputs.

The device allows:

• through the digital or relay outputs

– to switch a solenoid valve

– to activate an alarm

– to generate a flow rate proportional frequency

• through the analogue output to establish a control loop

2.2. Batch controller

The device needs a voltage supply of 12…36 V DC or 115/230 V AC.

The device is equipped with:

• four digital inputs (DI1 to DI4),

• two transistor outputs (DO1 configured as a pulse output and DO4 configured as state output, by default),

• two relay outputs (DO2 always configured to control the valve and by default parametrise of 100 % of the batch

quantity and DO3 configured as alarm output by default),

• two volume or mass totalizers and two totalizers for the number of batches performed.

The second relay output can be used to activate another valve, to initiate alarms or to generate warnings.

When mounted in a pipe in series with one or two valves, the batch controller makes it possible to carry out a dosing

of one or several quantities of liquids. The unit controls the opening of the valves and measures the quantity of the

fluid which flows. The unit also closes the valves when the pre-set quantity has been delivered.
