Flotect ® The V6 flow switch has a compact structure and is specifically designed to monitor the flow rate of liquids, gases, or air. It uses magnetic action and has no mechanical connection, making it easy and reliable to operate. The lower body is equipped with blades and a magnet, and the switch is operated by controlling the magnet in the upper isolation chamber. In most applications, the switch is normally open, and the fluid in the pipeline compresses the blade spring. When the flow rate decreases, the spring pushes the blade back to its original position, triggering the switch to sound an alarm or close. A three-way valve can be selected for easy installation of this flow switch. The pipe size for three-way installation is 1/2 ˝ -2 ˝, which is suitable for 1/4 ˝ and 3/8 ˝ pipes when a sleeve is added.

：：feature：：

• Leak proof lower body processed from bar material

During three-way installation, calibration blades or on-site adjustable blades are optional

• 24/7 protection

Explosion proof (listed in the technical specifications)

• Electrical components can be easily replaced without disassembly, ensuring efficient operation

The artistic process will not be interrupted

Using brass body can achieve high pressure up to 1000 PSI (69 bar), using 316 stainless steel body

Available to2000 PSI (138 bar) (see technical specifications)

The low flow rate model has a set value on-site adjustment function

Easy to install, simply insert the tee into the pipeline and connect it to the power supply

Typical applications:

• Protect pumps, engines, and other equipment at low flow rates or in the absence of fluid

• Control the timing operation of the pump

• Automatically start auxiliary pump and engine

Stop liquid cooled engines, machines, and machining processes when coolant flow is interrupted

Turn off the heater when there is no airflow passing through the heating tube

• Control the gate according to the flow rate

• Sound alarm when using emergency sprinkler
