Ultrasonic Level Sensor

Yes you can and there is a lot of information available if you run your query through google. They do have range limits and, of course, won't work in a vacuum.

Yes, check out www.bannerengineering.com go to measurement and inspection, then do some research on the U-gage ultrasonic sensors. I use them exclusively for material detection on indexing conveyors.

Good Luck

This technology is already widely used. For example the Ford GT is fitted with this technology supplied by TI Automotive. In Aerospace the Boeing 777 is also fitted with ultrasonic level sensors in all of its fuel tanks supplied by Smiths Aerospace. Custom ultrasonic sensors can be supplied by companies such as Airmar and Morgan Electro Ceramics (www.morganelectroceramics.com)

Dear Rayan,

Basicly major petrol station and industrial used ATG (aoutomatic tank gauging System). They have ultrasonic rod c/w water sensor and Leval sensor (Both detection and can flooting).

I suggest you go to www.ronan.com for future explenantion.

Thank you

What sort of fuel? If it has a flammable vapour above it then hazardous area equipment must be used to eliminate the risk of fire and explosion

Rayan,

Well, let us see if we can make it simple. Ultrasonic waves travel in the material of fuel tank (usually plain carbon steel) with a specific velocity and with different velocity in the fuel. If there is no liquid in the tank, u-waves will return back to the front of the fuel tank plate after hitting the backwall (or the inner side of the tank plate) as they can not travel so efficiently through the air. The time spent in this travel (to and fro) represents one thickness of the plate. Now, if on the other side we have fuel in the tank, part of the waves will travel through it and hit the opposite inner side of the tank and the backwall there and return to the probe (sensor - transmitter/receiver). Obviously, this time will be much more (depends on the tank plate thickness (x2), diameter of tank, type of fuel). This all can be established beforehand by 'calibrating' the test set up. If you are using a CRT for display you can see different echoes on it when fuel is present, or in a digital instrument the difference in travel time should indicate at which level we have fuel in the tank.

Hope it helps.

regards,

Nachi
