515/2536 Rotor-X Paddlewheel Flow Sensors

Simple to install with time-honored reliable performance, Paddlewheel flow sensors are highly repeatable, rugged sensors that offer exceptional value with little or no maintenance.

The output signal of the Model 515 is a sinusoidal frequency capable of driving a self-powered flowmeter (Model 5090) and has a wide dynamic flow range of 0.3 to 6m/s (1 to 20 ft/s).

Model 2536 has a process-ready open collector signal and has a wide dynamic flow range of 0.1 to 6 m/s (0.3 to 20 ft/s). Both sensors measure liquid flow rates in full pipes and can be used in low pressure systems.

525 Metalex Flow Sensor

The Signet 525 Metalex Flow Sensor offers the added strength of an all stainless steel construction with insertion paddlewheel technology. The result is a highly reliable sensor resistant to extreme pressures and temperatures. The Tungsten Carbide shaft with Fluoroloy B® bearing provide an increased length between maintenance. A comprehensive fitting program allows installation in steel lines with the mini-block for 16px diameters, and either the mini-tap or saddle for pipes up to DN300 (12 in.). The self-generating signal output allows use with battery operated flow monitor (8150).

2540 Stainless Steel High Perforrmance Flow Sensor

The Signet 2540 Paddlewheel flow sensor offers the strength and corrosion resistance of stainless steel for liquid applications with low velocity measurements. Unique internal circuitry eliminates the need for magnets in the process fluid, enabling flow measurement of 0.1 to 6 m/s (0.3 to 20 ft/s) while maintaining the advantages of insertion sensor design. Sensors can be installed in DN40 to DN600 (1.5 to 24 in.) pipes using the 1.5 inch NPT or ISO 7/1-R 1.5 threaded process connection. The sensors are also offered in a hot-tap configuration with a bleed valve for installation in pipes up to DN900 (36 inches) and service without process shutdown.
