Abstract
PURPOSE:To provide a small-sized and durable flow rate detector wherein water current in a water pipe is detected by a strain gauge held by an elastic body and a valve may be opened at a slight displacement of the water current. CONSTITUTION:A displacement-detecting member comprising holding a strain gauge 7 by an elestic body such as rubber is provided in a detecting member 6 which detects water current in a water pipe by a pressure difference at a Venturi section 9 formed in a water pipe 3. An electromagnetic valve opens and shuts according to an output from the strain gauge 7, placing an amplifier therebetween.
