Leading Manufacturer, Supplier & Retailer of Side Mounted Level Switch, Top Mounted Float Level Switch, Rotary Paddle Level Switch and up to 50 mtr cable float switch.
side mounted level switch is a point level sensor installed horizontally on the side wall of a tank or vessel to detect liquid level at a fixed point.
Working principle
Most side-mounted switches are float-type (magnetic):
A float is attached to a pivoted arm inside the tank
The float contains a permanent magnet
As liquid level rises or falls the float moves up/down
The magnet approaches a reed switch / microswitch inside the housing
This triggers an ON/OFF electrical signal
Inst Tools +1
So it works based on buoyancy + magnetism.

Water storage tanks
Oil & fuel tanks
Boiler drums
Chemical processing vessels
Pump control (start/stop)
High-level / low-level alarms
CPI Technology
top mounted float switch is one of the most widely used liquid level switches in tanks and vessels. It is installed from the top of the tank and works using a floating element that moves with the liquid level.
Top Mounted Float Switch
It is a level detection device where:
A float rises and falls with liquid
Movement activates an internal switch (usually magnetic reed type)
It gives an ON/OFF output for control
Commonly used for high level / low level detection
Applications
Water storage tanks
Overhead tanks (auto pump control)
Chemical tanks
Oil & fuel storage
Sewage and wastewater systems
rotary paddle level switch is an industrial level sensor used to detect the presence (or absence) of solid materials like powders, grains, pellets, or bulk solids inside bins, silos, or hoppers.
It works as a point level detector (not continuous measurement). It tells you:
Material has reached this level (High level)
Material has fallen below this level (Low level)
Working principle (simple)
A motor rotates a paddle (blade) inside the container
When there is no material, the paddle spins freely
When material covers the paddle, rotation is blocked
This triggers a switch signal (ON/OFF alarm or control)
Once the material level drops, the paddle rotates again and resets automatically
Where it is used
Common in industries handling bulk solids:
Cement plants
Food grains & flour mills
Plastic granules
Coal, sand, fly ash
Chemical powders
cable type float switch is a simple, reliable device used to automatically control liquid levels (usually water) in tanks, wells, or sumps.
A cable float switch consists of:
A floating body (usually plastic)
A cable with a weight
An internal switch mechanism (like a ball or mercury-free contact)
How it works
The float sits on the surface of the liquid.
As the water level rises or falls, the float tilts.
This tilt activates an internal switch, which:
Turns ON a pump (when water is high), or
Turns OFF a pump (when water is low)
Types of operation
Normally Open (NO) closes circuit when level rises
Normally Closed (NC) opens circuit when level rises
Can be wired for:
Filling control (overhead tanks)
Emptying control (sump/drainage)
Common applications
Water tanks (overhead & underground)
Borewells
Sewage and drainage systems
Industrial liquid tanks
