Often A typical float and board-level sensor would consist of a float, dust-proof pulley housing, pointer cradle with nylon, and 150 mm screen printed aluminum scale. This instrument is an absolutely reliable and accurate system for liquid level measurement in tall overhead tanks.
These types of float and board-level indicators basically work on the principle of buoyancy. The float is well connected to the counterweight along with a pointer through flexible wire ropes. The pointer slides along the guide against a graduated scale to indicate corresponding levels inside the tank.

 

 

Most often, the floats and board-level sensor find their application in overground and overhead storage tanks. They are also used in storage tanks of petroleum products, like furnace oil, diesel, lube oil, and so on. Also, it is used in the storage of vegetable oils, molasses, silicates, glucose, and so on. In short, the float and board-level indicators are most widely used in all non-hazardous and non-pressurized tanks.

 

About this item

Water level sensor-- featured by high accuracy, high reliability and easy installation, float provides you much convenience.

Liquid water level sensor-- the float can be installed at the top or bottom of the tank, a kind of liquid level control device.

Water level -- 304 stainless steel material made, float is durable for long period, providing you with a long term service.

Float ball -- the float is widely applied for fish tank and aquarium, waterfall and more.

Magnetic Level Gauge Accessories

Magnetic level indicators are available with a range of accessories, the most common being;

Calibrated Scale

A calibrated scale, attached to the magnetic level indicator allows the level to be read in units or percentage. The scales are most commonly manufactured from traffolyte or 316 stainless steel and engraved with the appropriate units.

Reed Switches

A magnetic reed switch mounted on the external wall of the gauge allows for level alarms and or executive actions to be taken e.g. switching on or off of a pump. Reed switches are widely used and provide a highly reliable and safe operation.

Reedchain Transmitter

A a magnetic level indicator can easily be converted into a magnetic float level transmitter by addition of a reedchain. A reedchain transmitter comprises of a chain of switches evenly spaced at intervals of 5mm, 10mm or 20mm gaps. As the float moves along this chain, the magnetic field generated by the float closes the reed switches changing the resistance in the circuit, the resistance output is proportional to the level of the liquid.

Float Damper Springs

Float damper springs can be installed at either the top, bottom or both ends of the chamber. Damper springs are considered when it is necessary to protect the float from damage in the event that there is a sudden loss or surge of pressure in the system.
