ABSTRACT:
Electrical pulse generator to operate a remote water meter indicator in which the pulse generator is driven by the drive of the meter to cause a magnetic circuit to be opened and closed in accordance with the rotation of the meter drive. The magnetic circuit is opened and closed in a manner whereby a linear force element, i.e., a spring, is acting against a magnetic gap so that the spring is sufficient to overcome the magnetic force and open the gap to cause a large change in the reluctance of the magnetic circuit, generating a pulse in a coil which can be then used to drive a remote reading meter.
