Malema flow switches are used in many applications for gases and liquids.
Paddle flow switch operation.
R1 bspt 1 npt pipe sizes.
When the liquid is static or nonexistent the spring is fully extended pulling the magnet downward and opening the switch.
Flow switches are used to determine if the flow rate of a fluid is above or below a certain a set point which can be fixed or adjustable.
Switch with an enclosure that meets nema 4x provides protection from dirt washdowns and corrosive liquids.
Spdt microswitch mains rated 120 240vac adjustable range.
1 larger temperature.
Gems sensors offers a broad range of flow switch configurations for use in liquids or gases that feature high quality corrosion resistant materials for use in tough environments with material choices ranging from stainless steel to ryton for vast chemical compatibility.
Paddle flow switches are for flow no flow detection in large line sizes engineered for positive liquid flow detection at pressures up to 2000 psig 138 bar unique patented cam design assures low pressure drop and does not require bellows seals or mechanical linkages.
A flow switch operates by conveying a trip motion relay reed switch paddle to another machine within the system usually a pump.
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.
Up to 11bar both fs8 w fs8 wj are stocked parts.
Dwyer flow switches are economical and reliable.
The trip signal will indicate to the pump to turn on or turn off.
In most applications the switch is normally off while there is sufficient flow of liquid or air.
Paddle flow switches or vane sensors with an electrical contact output are at a specific flow rate.
Flow switches are mechanical devices used in controlling the flow of air steam or liquid.
Flow switch can detect liquid movement in pipes.
In the presence of fluid flow controlled movement of the piston actuates an external hermetically sealed reed switch this switch can be used to actuate audible or visual alarms as well as relays or other controls.
At preset rates ranging from 50 cc min to 100 gpm gems switches will initiate alarm actuation or automatic shut down of a.
Operation is simple and dependable.
When flow stops the vane spring moves the vane actuating a single pole double throw switch rated 5a 120 250 vac to start or stop motor pump engine etc.
As flow occurs and the paddle is thrusted forward 20bc 30 c or more the paddle will push the magnet upward and actuate the switch closing the circuit.
The flow rate varies based on the pipe size and paddle used.
Mcdonnell miller fs 8 weatherproof paddle flow switch.
Refer manual for flow setting vs pipe size paddle length process connection.
Switch with a 316 stainless steel body is more corrosion resistant than switches with a brass body.
Malema s application engineers are well trained and are ready to assist with custom calibration and sizing to deliver a flow switch that precisely suits your application.
