+GF+signet 3-2540/3-2517流量传感器的比较和选择
2540高性能流量传感器
2540型叶轮式流量传感器采用了不锈钢材质，因此具有很好的强度和耐腐蚀性。的内部回路结构使它在测量过程中无需放置磁体，因此也具有了很高的灵敏度。它的测量范围为：0.1-6m/s.FluoroloyB /PTFE材质的轴承和钨碳合金的轴提供了相当高的耐磨性能。2540型传感器提供现场可更换的电子单元，并有突变电压抑制器（TVS），对大电压（如雷电）引起的现场线路的冲击干扰，具有很强的抗扰性能。
·能够兼容的Signet变送器：8550，8900，5600
·适用的领域：流速较低，或其工作压力较高，不适用于纯水
相对3-2517,2540线圈不带磁性,如用户管道中如有细小铁屑等,不会吸附在转子上.造成测量的偏差.
2517铜质叶轮流量传感器
2517型叶轮式流量传感器采用了增强的坚固的铜质结构，适用于多种应用情况。它具有较宽的流量范围：0.5-6m/s。能测量满管流量和适用低压系统。FluoroloyB/PTFE材质的轴承和钨碳合金的轴提供了相当高的耐磨性能。2517型铜质传感器，在与8150电池供电的累加器结合时，传感器的流量信号可实现远程累加。传感器适用的安装管径为：DN40-DN600。采用1.5in.（或ISO7/1-R1.5）螺纹的过程接头。2540传感器可提供带排放阀的Hot-Tap结构，可实现不关闭过程管道进行装卸，管径上限为DN900。
选型
3-2517.100 订货号 198840003 接头类型:1.5 inch NPT
3-2517.101 订货号 198840007 接头类型:1.5 inch ISO
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.
