The +GF+ Signet 525 Metalex™ Paddlewheel Flow Sensor is an insertion paddlewheel flow sensor for liquid flow measurement in compatible steel piping installations.
It combines stainless-steel construction with paddlewheel sensing technology and is used with Metalex tee, socket-weld mini-tap, weld-on mini-tap, or saddle fitting configurations as specified by model and pipe size.
Process Controls Corporation supplies the Signet 525 Metalex™ Paddlewheel Flow Sensor for industrial customers matching flow instrumentation to pipe size, fitting style, rotor shaft material, and compatible GF Signet instrument requirements.
The Type 525 Metalex™ family includes self-powered sensor configurations with a 7.6m (25 ft) cable and is not suitable for gases.
