Remote reading device for standard water meter - comprises small permanent magnet on indicator needle with magnetic reed switch sensing needle movement and connected to external cable
The supplementary magnetically operated reed relay and associated cable which can be installed in a standard Wortmann water meter to allow remote monitoring of water consumption. The water meter if driven from a water screw via a magnetic coupling (1) and comprises a number of geared parts with two indicator needles (4, 5) all mounted in a sealed unit (5, 7, 8) within an outer casing (9, 10) which is not sealed. These casings allow the meter to be read through suitable windows (10, 6). A small permanent magnet (12) is mounted on the main counter needle during manufacture, and this allows a magnetically operated feed relay (14) to be mounted outside the seal but inside the outer casing, when required. A relay cable (15) can be threaded through the interstices in the outer casing to a remote counter.
