Electronic Flow Indicator ZVL

The electronic flow indicator “ZVL” series allow the commutations of an electric contact  when the preset flow values is reached, with the possibility to set  also the reset value.
The display shows the flow rate in percentual and not in litres, indicating zero for the starting value and 100% at maximum flow for all end of the scale.
