Simple to install with time-honored reliable performance, Model 515 Rotor-X 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 (Signet Model 5090). The wide dynamic flow range of 0.3 to 6m/s (1 to 20 ft/s) allows the sensor to measure liquid flow rates in full pipes and can be used in low pressure systems.

The Model 515 sensors are offered in a variety of materials for a wide range of pipe sizes and insertion configurations. The many material choices include PP, PVDF, and Tefzel make this model highly versatile and chemically compatible to many liquid process solutions. Sensors can be installed in up to DN900 (36 in.) pipes using Signet's comprehensive line of custom fittings. These custom fittings, which include tees, saddles, and weldolets, set the sensor to the proper insertion depth into the process flow. The sensors are also offered in configurations for wet-tap and intrinsically safe installation requirements.

The Signet 3519 Flow Wet-Tap Valve serves as a unique interface between the installation fitting and the Wet-Tap style Signet 515 or 2536 Rotor-X flow sensor.  It provides a fast method of removing the sensor from the pipe under specified operating pressures.  The PVC &stainless steel design of the Wet-Tap makes it resistant to corrosion and chemical attack by acids, alkalies, salt, and a number of other harsh chemicals.

The Signet 3519 Wet-Tap Valve mounts directly onto standard Signet installation fittings.  The 3519 Wet-Tap consists of a flange and support plate that threads onto the pipe fitting insert, and a PVC ball valve through which an extended length sensor is inserted into the pipe.

The Signet 2517 Paddlewheel Flow Sensors offer added strength and durability of brass construction for a variety of applications. The wide flow range of 0.5 to 6m/s (1.6 to 20 ft/s) allows the sensor to measure liquid flow rates in full pipes and can be used in low pressure systems. Fluoroloy B bearings and a Tungsten Carbide pin provide exceptional wear resistance. The 2517 brass sensor signal allows for remote totalization when coupled with the 8150 Battery Powered Flow Totalizer. Sensors can be installed in DN 40 to DN 600 (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 DN 900 (36 in.) and allows for servicing without process shutdown.

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. Fluoroloy B® bearings and Tungsten Carbide pin provide exceptional wear resistance. The model 2540 offers field replaceable electronics and transient voltage suppression (TVS) to provide greater immunity to large voltage disturbances (ie. lightening) sometimes encountered in field wiring. Sensors can be installed in DN 40 to DN 600 (1½ to 24 in.) pipes using the 1½ 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 DN 900 (36 inches) and service without process shutdown. Both styles of sensors must be used in full pipes and can be used in low pressure systems.
