Overview
The Omega FP-5300 paddlewheel flow sensor is an electro-mechanical volumetric flow transducer designed for accurate, cost-effective flow measurement in industrial piping systems. This RTR-X series variant utilizes durable polypropylene and titanium construction with PVDF materials, providing exceptional chemical resistance for corrosive and ultra-pure liquid applications. The FP-5300 generates a sinusoidal AC signal output with frequency directly proportional to flow velocity, enabling reliable integration with flow meters, controllers, and data acquisition systems.
