These water-meters are suitable for totalization of clean or slightly dirty liquids, raw water or demineralized water.

M25 and M40 are volumetric counters, suitable for totalization of clean or slightly dirty liquids.
A gridd located at the inlet, protects the measuring chamber from possible introduction of particles.

Operation:
Lower and upper parts of measuring chamber are spherical in shape. Inside the chamber is the disc, which is set in motion by the liquid. The flow causes an oscillating movement of the disc, opening and closing alternately the inlet and outlet orifices of the measurement chamber. The frequency of disc oscillations is magnetically transmitted to the totalizer.

Commissioning
The water-meter must be installed on a horizontal pipe, full of liquid.

Displays and remote signals (3 possibilities):
• Totalizer: 6 reading rollers
• Emitting head (1 or 10 pulses per liter) without display
• Emitting head (1 or 10 pulses per liter) without display LCD (Reset function by REED contact - Max. 20 Hz - 24 V - 50 mA)
