ABSTRACT:
A flow-sensing configuration embodies straight-through geometry between inlet and outlet ports, all on a single central axis, using reed-switch and magnet technology to produce a logic output. Virtually all parts are of molded plastic, and the inlet and outlet port connections avoid thread formations by providing for sealed insertional reception of standard tubing at these port connections. When thus incorporated into a hydraulic system, the inlet and outlet tubing insertions at the respective ends of the flow sensor inherently retain integrity of flow-sensor assembly into the system. Flexibility of serving specific interface needs of the customer is achieved by using snap-in modular parts at the port connections.
