HZ 5 RR oil meter with built-in reed contact as “pulse generator” and mechanical drum-type register

In addition to the rolling-meter, the HZ 5 RR has a built-in po- tential-free reed contact. When the flowrate is 0.1 l, then the reed contact will emit one impulse.

or similar R can also be plugged into the downstream inlet: at least 10 kohm
Reed contact: Pulse value: 1 Pulse = 0.1 l
Type of contact: max. electricity 70 mA/max. voltage 30 V
NO switch: Integrated protective resistor RS: 100 Ohm/ 0.6 W
voltage drop across Rs at 10 mA: 1 V
Pulse Frequency: at 40l/h ca. 0.2 Hz
Attention: Avoid contact with the magnetic field e.g. fan or solenoid valve.
On the relay contact be mindful of the flyback diode.
Do not connect the low-impedance voltage source parallel to the clamp!
