FLOW LEVEL SENSING SYSTEM WITH FLOW ELECTRICAL TRANSDUCER, AND ITS APPLICATION

摘要

A flow rate sensing system with a flow-electrical transducer for the monitoring of the flow of a medium by at least one electrically heatable resistance wire which is incorporated directly into the thermoplastic flow channel wall, the resistance wire has areas of small and large diameters with the small diameter portion in the flow channel and the large diameter imbedded in the wall of the flow channel.
