Fluid flow detection with floating magnet for activation of an electronic circuit breaker with float

摘要

A tubular section (1) of the device has a truncated cone area (2) with an internal shape (2i) which narrows towards its lower end. A floating body (5) that moves in the tubular section has a conical shape matching that of the internal cone section, so that when it abuts the lower shoulder (6), body (5) and internal shape (2i) match. The variation in annular section as the body is lifted by an increasing flow compensates for loss of load so that the device operates more reliably.
