Widely used in household appliances, automotive applications and control technology.

Integral to process control in many industries, level measurement sensors fall into two main types. Point level measurement sensors are used to mark a single discrete liquid height–a preset level condition. Generally, this type of sensor functions as a high alarm, signaling an overfill condition, or as a marker for a low alarm condition. Continuous level sensors are more sophisticated and can provide level monitoring of an entire system. They measure fluid level within a range, rather than at a one point, producing an analog output that directly correlates to the level in the vessel. To create a level management system, the output signal is linked to a process control loop and to a visual indicator.

How Magnetic Reed Liquid Level Sensors Work

The purpose of a float switch is to open or close a circuit as the level of a liquid rises or falls. Most float switches are "normally closed," meaning the two wires coming from the top of the switch complete a circuit when the float is at its low point, resting on its bottom clip or stop (for example, when a tank is dry).

Most float switches utilize a magnetic reed switch to open or close the circuit. The reed is encased in a glass tube, which is cemented into a plastic or stainless steel stem with epoxy. The illustration to the left demonstrates how a magnet can be used to open or close a circuit by moving it closer to or farther away from a reed switch.

When the magnet comes close to the two contacts, they draw together and touch, allowing current to pass through. When the magnet is moved away, the contacts demagnetize and separate, breaking the circuit.

In a float switch, the magnetic reed switch is hermetically sealed in a stem, most often made from plastic or stainless steel. The float encases a sealed magnet, which moves up and down the length of the stem as a fluid level rises and falls.
As the magnet passes by the contacts in the encased reed switch, they draw together and complete a circuit between the two lead wires, as shown in the cutaway to the left.

The operation shown can usually be reversed by removing the bottom clip from the switch, inverting the float and replacing the clip. When this change is made, the switch circuit will be open when the float is resting on the bottom clip and closed when the float rises.
Properly used, float switches can deliver millions of on/off cycles, for years of dependable operation. Failures are normally due to overloading, frequently caused by spiking voltage.

gps tracking fuel level sensor
Application:Heavy duty truck,bus and offer Vehicles
Accurancy :5-21mm
Used for Fuel tank

gps fuel level sensor
The FLS-L is a cost effective fuel level sensor designed for smaller trucks.It could be easily adapted to different type of tanks and can be delivered with customzied sensor length, various fittings and output signal.The measurements are done by a series of reed switches positioned inside the level tube,a float with built in magnet moving up and down when fluid level changes, would triger the reed switches inside the tube respectively, thus, generate a potential free resistance signal with a Ohm value to indicate the change of fluid level.The switch contacts are hemetically sealed in the inert gas,and operated by a magnet, it is more reliable than the traditional resistive fuel level sensor.
