Micro Power Flow Sensor the FDT

FDT Flow Detector Transducer – With Logic Flow/No-Flow Output

FDT Micro-Power, ATEX Compliant, Flow Detector Transducer for Open Channels, Sewers, Ducts and Weirs.

Industry proven with over 1-million hours of fault free service, the FDT is a unique ultra low power flow detection device capable of detecting and reporting the flow of liquids, gases, powders, particles and even people/animals in a wide variety of applications.

The award winning FDT is detects flow derived from motion and in any direction and produces simple to interface output as a simple CMOS/TTL logic FLOW/NO-FLOW binary output. The FDT also includes a Mission Critical tamper loop to warn if the cable becomes severed.

Available with an Telemetry / IoT interface or as a stand alone sensor for OEM applications the FDT can be found in service globally from Europe to the US.
