2536 Rotor-X Paddlewheel Flow Sensor


Simple to install with time-honored reliable performance, Signet 2536 Rotor-X Paddlewheel Flow Sensors are highly repeatable, rugged sensors that offer exceptional value with little or no maintenance. The Model 2536 has a process-ready open collector signal with a wide dynamic flow range of 0.1 to 6 m/s (0.3 to 20 ft/s). The sensor measures liquid flow rates in full pipes and can be used in low pressure systems.   

The Signet 2536 Rotor-X Paddlewheel Flow Sensors are offered in a variety of materials for a wide range of pipe sizes and insertion configurations. The many material choices, including PP and PVDF, make this model highly versatile and chemically-compatible with many liquid process solutions. Sensors can be installed in DN15 to DN900 (½ to 36 in.) pipes (except the 2536 PVC versions, which can be installed in DN15 to DN100 (½ to 4 in.) pipes), using Signet's comprehensive line of custom fittings. These custom fittings, which include tees, saddles, and weldolets, seat the sensor to the proper insertion depth into the process flow.
The sensors are also offered in configurations for wet-tap installation requirements.
