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®/PTFE 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. lightning) sometimes encountered in field wiring. Sensors can be installed in DN40 to DN600 (1.5 to 24 inch) pipes using the 1.5 inch or ISO 7/1-R 1.5 threaded process connection. The sensors are also offered in a hot tap configuration with a bleed valve service without process shutdown in pipes up to DN900 (36 in.). Both styles of sensors must be used in full pipes and can be used in low pressure systems. Typical applications:
- HVAC
- Turf Irrigation
- Cooling Systems
- Filtration Systems
- Water Distribution
- Leak Detection
- Pump Protection
- Clarified Effluent Totalization
- Ground Water Remediation
- Gravity Feed Line
- Not suitable for gases
