Vane Type Flow Switch Working

A vane operated flow switch relies on fluid pushing against an internal paddle.

Vane type flow switch working.

Applications include steam flow boiler feedwater and fluid flow rates in building water lines. Peeco flow switch peeco flow switch. Designed for use wherever there is an application for a conventional flow orifice plate. Flow switch operating principle is based on a free floating magnetic piston which responds only to the motion of fluids within the line not to static or system pressures.

The n series non explosion proof flow switch e series explosion proof flow switch and h series high pressure explosion proof flow switch. Flowtech vane type flow switches are designed for reliable supervision of liquid flow through pipelines. Orifice plate flow meters are differential pressure sensors for flow rate. As the name stipulates they feature a vane or paddle that sits in the path of water and moves when it flows.

The vsr may also be used as a sectional water flow detector on large systems. Lpc approved sizes are 2 thru 8 50 mm thru 200 mm. Delay units are available to prev. Variable area flow switch.

In addition to general environments these flow switches can be used in adverse weather conditions. Can be used with gases liquids corrosive and high temperature fluids. Schedules 10 through 40 sizes 2 thru 8 50 mm thru 200 mm. Power engineering equipment company peeco flow switches have been made in the usa offered in 3 different series.

As the flow drops to preset levels it triggers an internal magnetic mechanical and coupling switch actuation lever which essentially trips the switch. This device has an internal piston which activates the switch. Much like their water paddle flow switch equivalents a paddle air flow switch sometimes known as a vane type switch is a mechanical sensor that partially protrudes into the duct being monitored. These vane operated flow no flow switches come with the following advantages easily configurable flow monitoring and control.

Vane type water flow switches are used to generate a fire alarm signal based on a water flow discharge event from a wet pipe fire sprinkler system. Peeco flow switches are simple mechanical devices. In the presence of fluid flow controlled movement of the piston actuates an external hermetically sealed reed switch. It is ul listed and fm approved for use on steel pipe.

Working principle of flow switch with animation. These devices sometimes fail and often they are incorrectly installed maintained or tampered with. Vane or paddle type flow switches work in wet pipe systems only. They are used in sprinkler system to transmit electrical information due to the flow when a sprinkler head gets activated.

This switch can be used to actuate audible or visual alarms as well as relays or other controls. The model vsr is a vane type water flow switch for use on wet sprinkler systems.
