GF Signet P51530-P0 515 Rotor-X Paddlewheel Flow Sensor | 1/2" to 4" Pipe | Easy Installation
Engineered for straightforward installation and proven reliability, the GF Signet 515 Rotor-X Paddlewheel Flow Sensor delivers highly repeatable measurements with minimal maintenance requirements. This durable, black-housed sensor provides outstanding value across a wide range of liquid flow applications. Designed for pipes from 1/2 inch to 4 inches, it generates a self-powered sinusoidal frequency signal capable of directly driving compatible flow meters like the Model 3-5090.
Product Features and Typical Applications
Featuring an extensive dynamic flow range of 1 to 20 ft/s (0.3 to 6 m/s), the Model 515 is ideal for measuring liquid flow in full-pipe, low-pressure systems. Its wide 20:1 turndown ratio ensures accuracy across varying flow conditions. Available in multiple material configurations—including chemically resistant PP and PVDF—this sensor offers exceptional versatility and compatibility with diverse process liquids.
