System for monitoring flow of fluid in conduit, comprises turbine which is driven by fluid flow and drives generator connected to battery feeding microprocessor which controls alarms and valves

摘要

In the case of a water supply to a dwelling the water in the supply conduit (1) drives a turbine (2) which drives a generator (4). The generator charges a battery (5) which supplies actuators (10a,10b,10c) for valve (12) control, local alarm and radio alarm. The actuators are controlled by a switch (9) controlled by a microprocessor (7) which receives data from a rotation detector (6) on the turbine and is supplied from the battery An Independent claim is also included for : Equipment used by the system including a turbine with magnetic coupling to the generator, a rotation detector emitting impulses and actuators for valve operation and local and remote alarms
