These products are used for water level monitoring, tank level controls, industrial water control, pump automation and much more. Some are designed to float in tanks and others mount through the walls of tanks and other vessels. Find a wide selection of these switches to fit your application.


Dwyer F6 & F7 Series Level Switches - Vertical-

Dwyer F6 & F7 Series Level Switches - Vertical

Combine low cost and reliability with fast, simple installation. Hermetically sealed reed switches are actuated by magnets permanently bonded inside the float and can be easily adapted to open or close a circuit on rising or falling levels.


Dwyer F6 & F7 Series Level Switches - Horizontal/Specialty-

Dwyer F6 & F7 Series Level Switches - Horizontal/Specialty

Series F6 & F7 Horizontal Mount Level Switches are designed to mount through the walls of tanks and other vessels. Series F6 & F7 Specialty Level Switches are designed for unique applications.


Dwyer FSW2 Series Free-Floating Level Switches-

Dwyer FSW2 Series Free-Floating Level Switches

Mercury-free self counter-weighted floating switch designed for the automation of pumps, specifically filling and draining of tanks, wells, and reservoirs. The FSW2 body is free of any irregularities making it ideal for use in sewage water applications. Cable hangers are available to suit a variety of mounting applications.


Dwyer L8 Series FLOTECT Liquid Level Switches-

Dwyer L8 Series FLOTECT Liquid Level Switches

Features a leak proof body and float constructed from tough, durable polyphenylene sulfide which has excellent chemical resistance. Because the liquid level snap switch is magnetically actuated, there is no direct mechanical linkage to leak or fail, assuring longer life and decreased maintenance costs.


Dwyer OLS Series Optical Level Switches-

Dwyer OLS Series Optical Level Switches

Low cost, rugged optical level switch provides rapid response while employing no moving parts for stable process control. The bright red and green LED's indicate the presence or absence of liquid for true, local indication. Three optional materials, 316 stainless steel, polysulfone and PFA provide application flexibility.


Dwyer L6 Series FLOTECT Liquid Level Switches-

Dwyer L6 Series FLOTECT Liquid Level Switches

Designed and built for years of trouble-free service in a wide variety of process liquid level applications. Operation is simple and dependable with no mechanical linkage as the level switch is magnetically actuated. The float lever pivoted within the body moves when the process liquid displaces the float.


Dwyer DBLM Series Mini-Bin Dry Bulk Level Monitors-

Dwyer DBLM Series Mini-Bin Dry Bulk Level Monitors

The Mini-Bin provides reliable level sensing for dry bulk solids where mounting space is limited. This compact, side mount control reports high, intermediate, and low level conditions, eliminating overflows, choking, clogs or empty vessels. Model DBLM Mini-Bin operates by using a 1 rpm synchronous motor to rotate a four vane, plastic paddle.


Dwyer CFS2 Series Cable Float Switches-

Dwyer CFS2 Series Cable Float Switches

Mechanically actuated floating switch intended to activate electrical components, usually pumps, to start and stop automatically. The CFS2 is perfect for simple level control of liquids for filling or draining reservoirs and tanks. Counterweights and cable hangers are available to suit a variety of mounting applications.


Dwyer L10 Series FLOTECT Mini-Size Level Switches-

Dwyer L10 Series FLOTECT Mini-Size Level Switches

Wide media compatibility is assured with a choice of brass or stainless steel bodies and external tees; polypropylene or stainless steel floats. Two basic configurations are offered; with 1" NPT male threads for direct side mounting through a half coupling or with factory installed tee for external mounting.


Dwyer L4 Series FLOTECT Float Switches-

Dwyer L4 Series FLOTECT Float Switches

Operates automatically to indicate tank level. Perfect for starting or stopping pumps, opening or closing valves, or actuating level alarm signals. A unique magnetically actuated switching design gives superior performance. There are no bellows, springs, or seals to fail. Float arm hinge design limits the arm angle to prevent vertical hang up.


Dwyer PLS Series Paddle Level Switches-

Dwyer PLS Series Paddle Level Switches

A 1 rpm synchronous motor rotates the paddle, utilizing a magnetic drive. As product builds up, the paddle is impeded from moving and the resulting motor torque activates the output switches and stops the motor. A spring mechanism reactivates the motor and returns the switches to normal state when the product no longer impedes the paddle rotation.


Dwyer PS Series Proximity Sensors-

Dwyer PS Series Proximity Sensors

Noninvasive sensors ideal for level detection, position indicating and counting applications. Capacitive type sensors detect electrically conducting and nonconducting materials, liquids, solids, or powders and include a sensitivity adjustment to differentiate between various materials. Inductive sensors detect ferrous or nonferrous metals only.
