相对3-2540,2517线圈带磁性,如配合3-8550使用,则可以不需要附件电源.更加方便.如水中无金属杂质,则适合使用+GF+signet 3-2517的流量传感器.



3-2540系列详细英文介绍

2540 Stainless Steel High Performance 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. Rulon® B （Fluoroloy B®/PTFE） bearings and Tungsten Carbide pin provide exceptional wear resistance.

The Signet 2540 offers field replaceable electronics and transient voltage suppression （TVS） to provide greater immunity to large voltage disturbances （i.e. lightning） sometimes encountered in field wiring. Sensors can be installed in DN40 to DN600 （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 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.
