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) sometime encountered in field wiring. 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. Both styles of sensors must be used in full pipes and can be used in low pressure systems.
