Product Features

*Precise linear and temperature compensation

*ZERO and RANGE self-calibration

*Adjustable damp output time

*Strong interference resistance and shock resistance

*Surge, over-current and polarity resistant circuit design

*Applicable for various non-conductive liquids

Applicable Scope

*Liquid level measuring and control in the industrial course

*Oil level measuring for automobile oil tanks, tankers and oil depots

*Measuring and control of other non-conductive liquid



HPT621 capacitance fuel level sensor is the customized sensor meter for precise measuring of the fuel oil level of automobile oil tanks, tankers, locomotives and oil depots, etc.

The whole series capacitive level sensor are capable of self-calibration. The user can realize the ZERO or RANGE self-calibration with two buttons or two lead lines to meet different requirements on various complex occasions. 


Features of capacitive liquid level sensor

1.Convenience: it can be installed by flanges, simple and easy to operate.

2.Independence: It can measure the oil quantity directly to achieve the fuel consumption value, it will not be any action and without affecting to the oil system / pipeline.

3.Uniqueness:the user can do recalibration through the button, digital output is also available with debugging software.

4. Self adjustability: according to the different size of tank, user can adjust the range of the sensor and do

installation; sensor increases temperature compensation function, correct error automatically due to fuel volume

change caused by the change of the temperature.

5. Safety: It can replace the original vehicle oil gauge directly, no need to drill in tank to install capacitance sensor, electronic cabin is explosion-proof design and get the explosion-proof certificate; sensor flange with two layers of the anti leakage groove, prevent oil leakage problems.

6. Stability:no mechanical moving parts, mature and stable circuit structure and components of good quality will make the sensor be used continuously for years without changing.
