Contactless Ultrasonic Liquid-level Meter series AVA-1

Application:

Contactless ultrasonic fuel-level meters are designed for measuring liquid level without putting it in a liquid. They should be used in combionation with GPS/ GPRS tracking systems.

The contactless ultrasonic fuel-level meters conform to the most strict fire and explosion safety requirements.

The ultrasonic fuel-level meters could measure level of the following liquids:
— Gasoline
— Diesel
— Liquefied gas
— Alcohol
— Acid
— Kerosene
— Paint
— Solvent
— Etc.

Default setting of the measuring liquid is diesel. For the other liquids corresponding settings should be made.

Specific features of the ultrasonic fuel-level meters:
1. Superimposed method of the installation without tank drilling
2. No contact with the fuel
3. High fire and explosion safety
4. High measurement accuracy
5. Thermo compensation
6. Compatible with any GPS/ GPRS tracker
7. Possibility of autonomic usage
