ABSTRACT:
The invention pertains to a rotation gauge for a water meter register where the hydraulic part of the meter rotates a shaft whose revolutions are to be counted. At the other end of the shaft at least one magnet is driven by rotation by the shaft. Outside this hydraulic part, two flexible blade switches are mounted opposite the path of said magnet and connected to an electronic circuit which provides a register with metering pulses. The metering pulses are characterized by the fact that each of triggered by the closing of the first flexible blade switch and stopped by the closing of the second switch. The second switch is closed substantially in the middle of the period during which the first remains closed.
