DMZ-4.2W Flow Volume Counter
The DMZ-4.2W Flow Volume Counter is used for dosing or filling preset fluid volumes with two limiting values.
This unit also captures the flow rate and can therefore be used as an adjustable flow monitor. A freely configurable current output can be assigned either to the volume or to the speed.
Commercially available a flow sensors, which emit pulses proportional to the volume, are used as signal generators. These could be contact-equipped water meters or impeller wheel recorders, for example.
Multiple configuration and setting options enable the user to adjust the unit precisely to the given application.
