Flow sensor for domestic and commercial water supply systems has a sensor with a moving body whose movement is flow-dependent and which is used in conjunction with a non-contact proximity switch to output a measurement signal

摘要

Flow sensor has a moving body (6) that protrudes into a flow medium and is moved within its housing (2). The flow causes the body to move against a return force provided by a return spring (8). A contactless proximity switch (18) produces a signal dependent on the body position that is proportional to the flow being measured.
