Flow meter

摘要

A flow meter for measuring the consumption of a fluid such as tap water and indicating it digitally at a remote place from the detecting section, having a pulse generator; means for giving intermittent rotation to the rotor of the generator which comprises a cam plate with a dwell portion of the same radius and a plurality of recesses formed at the outer periphery thereof, a driving disc placed coaxially therewith and capable of rotating relatively to the cam plate within a prescribed angle, and an intermittently-driven member provided with a plurality of projections capable of being engaged with said recesses at the outer periphery thereof correspondingly to the cam plate and connected to the rotor shaft of the pulse generator; and a pulse motor capable of operating the indicating wheels by using the pulse voltage from the pulse generator.
