Fuel level sensoris a low cost capacitance type level sensor. It is designed for monitoring levels in fuel tanks of vehicles, Bulk storage tanks fitted on vehicles, diesel storage tanks. The Design is simple & light weight. It measures the level accurately and reliably. The sensor output is connected to vehicle monitoring and tracking system or level indicators. The sensor consists of measuring probe which is encircled with a reference probe. This given more linear output and is not affected by turbulence inside the tank. Fuel Level Sensor As the fuel level increases, the capacitance value also increases. The fuel acts as the dielectric between electrodes. The increase in capacitance directly proportional to increase in fuel level. This change in capacitance is measured and converted into 4-20mA, 0-5V, 0-10V, RS485 O/P.

Percentage Level Indicator is used to know the level of liquid in storage or process tank. The unit consist of a Percentage Level Sensor mounted inside the tank & a Digital Level Indicator mounted in control room or pump room or user accessible area.

Sensor 

The Percentage Level Sensor is a Magnetic Float Operated Level Sensor with ten set point with each set point equal to 10% of the tank depth. The sensor gives variable resistance output from zero U to 2.5k U. for each set point the output resistance will increase by 250 U.

Pump ON & OFF is provide in two modes :

• Pump UP mode : To Fill the tank. Here the pump is ON at Low Level & OFF at High Level. The High & Low Levels are field selectable between ten steps.
• Pump DOWN mode : To Empty the tank. Here the pump is ON at High Level & OFF at Low Level. The High & Low Levels are field selectable between ten steps.

Auto / Manual selector switch is provided for manual intervention. Similarly Alarm is between Low & High Level which is field selectable between ten steps. Digital Level Indicator also provides optional 4-20mA output. It is very useful for Water Sumps, Overhead Tanks, Diesel Storage Tanks, Diesel Day Oil Tanks, Oil Tanks, Chemical Tanks, Storage Tanks Etc.

Indicator 

Digital Level Indicator is a microcontroller bases electronic unit for display of level in percentage. The level is displayed as 0%, 10%, 20%, 30%, 40%, …………80%, 90% & 100%. The display is through Seven Segment bright LED display. The unit is connected to Percentage Level Indicator supplied by us. Digital Level Indicator comes with a unique feature of Dual option of Pump control Or Alarm facility. The unit can be used to either switch ON & OFF the pump or provide High & Low Level Alarm by selecting suitable DIP Switch.
