The SERIES TDFS Thermal Flow Switch uses impulse thermal dispersion measurement technique to indicate whether the flow rate is above or below a user set flow rate. It provides NO and NC NPN outputs and two LED, one green and one red for high and low set point indication.

The Series TDS Thermal Dispersion Flow Switch offers solid state flow detection of non-coating liquids for pump and process protection. SPDT output allows for interfacing with remote PLC or relay control device. The adjustable switch point is factory calibrated at 0.2 fps with LED indication of flow and calibration status. Units feature selectable NO or NC operation and are not damaged by overranging flow velocities.

Protect pumps and valves from dry running with the Series TSP Liquid Flow Controller. The Series TSP combine a liquid flow switch with a failsafe relay controller to detect a flow or no flow situation and provides switching for direct actuation of pumps and valves. Controller features adjustable time delay, selectable NO or NC operation, and LED indication of sensor, relay, and power status. Four models (TSP110S, TSP210S, TSP120S, TSP220S) are designed with an integral flash alarm to provide immediate indication of local alarm conditions.

V8系列 FLOTECT®靶式流量开关用于安全联锁系统中以保护系统和设备,操作简单可靠。在一般的应用中,当管线中有气体或液体在正常流动时,开关保持打开状态,当管线的流量低于某个设定值,或断流时,在弹簧的作用下,开关会闭合,它可发出信号去联锁启停马达,水泵,阀门,并发出报警信号,也可启动预先设定的应急方案来保护工艺过程和设备不受损毁。V8采用防泄漏全密封主体,材质为坚固耐磨的PPS工程塑料,它具有很好的耐腐蚀性能。可现场剪切靶式叶片,能安装于1到6英寸管道中,叶片上带有刻度,以方便剪切来调整设定点值。V8流量开关可耐压到150 psig(10 bar),耐温212℉(100℃),它可用于所有与PPS,陶瓷8,316不锈钢兼容的工业应用场合,它带有UL 508认证,满足工业安全环境标准。

FS-580 流量开关是专为HVAC 和制冷机应用设计的。独特的波纹管结构使得开关灵敏可靠,微动开关触电具有高开关能力。▲ 耐压高达1.7MPa▲ 可用于1" - 8" 的管道▲ 全铸铝外壳▲ IP65 外壳▲ 预涂螺纹胶应用·HVAC·制冷机组冷却系统·压缩机·热交换系统·涡轮机·发动机·蒸汽锅炉·电子管·泵出水监测

The Series AFS Adjustable Flow Switch is externally adjustable and is ideal for protecting machine tools from coolant flow failure, protecting bearings from loss of lubricant or assuring proper air flow. The Series AFS offers an infinite number of flow settings at pressures up to 1000 psig, with low pressure drop and precise repeatability. The AFS is housed in either brass or stainless steel and can be used with water, compatible liquids, oils, and gases.

透明的P5系列 PVC流量开关有耐用防腐的PVC外壳,透明可视,可直接观察流体的状态。它可预设设定点从0.5到2.0GPM,当流量增高时动作。在没有流动的情况下是单刀单掷常开。可选1/2" NPT 或 3/4" IPS (for 0.5 GPM) 或 1" IPS (for 2.0 GPM) 进出口接口。只有一个移动部件的穿梭式设计便于维护,使用寿命长,只需移除一边,不需要拆卸接管和外壳就能清洗。它结构牢固,耐化学腐蚀性能好,用于监测流量的流动状态。

P4系列 PPS活塞式流量开关为注塑成型塑料结构,性能优异。固定设定点从0.1到1.5GPM来监测液体的流量。可选常开或常闭的单刀单掷或单刀双掷的全密封干簧管开关。采用了PPS R4工程塑料外壳和活塞,316不锈钢弹簧,氟橡胶O型环,环氧树脂保护等。 进出口采用9/16"-18 UNF- 2B螺纹,可选1/8"和1/4" NPT螺纹或1/2" 推紧式接头。
