There are some popular names, which have always been facilitating people with various ultrasonic instrumentations and monitoring equipment from decades. Most importantly, these names have dominated the respective market in regards to the competitive ultrasonic liquid level indicator prices they offer such as Coltraco. Multiple options are available for people in accordance to the budget as well as requirement in the market to choose from. This makes the customers all around the world to demand the products they are dealing in.

How ultrasonic liquid level indicator operates?
The ultrasonic liquid level sensor uses ultrasonic technology to identify the interface between liquid and air in any single skinned container. It therefore has none of the user problems associated with radioactive liquid level indicators, which require dedicated training, storage, Health & Safety documentation, and transportation. It also replaces the traditional means of verifying liquid levels by dismantling and weighing in which the system may be closed down or disconnected, risking potential damage in so doing and involving considerable time, expense and inconvenience. Major accomplishment some companies have made so far regarding this product is regarding the introduction of better ways of measuring cylinders.

Applications of Ultrasonic Level Indicator
An ultrasonic liquid sensor is a versatile instrument that can locate the level of any liquid in any single skinned container of wall thickness 2–15mm. Wall thickness of 15mm–90mm is also possible, depending on material type and vessel size. It cannot monitor contents of plastic vessels, as they do not conduct ultrasound.

It is typically used for high pressure CO2 or Halon cylinders constructed of seamless spun steel, approximately 5 feet high, 10ins diameter, 45 kg or pressed steel with welded seams with low pressure fills of varying sizes and fill weights:
1.    Fire Extinguishing Cylinders:
Its primary application is to check levels of liquid gaseous extinguishing in fire cylinders where it can be used to locate levels of CO2, Halon and Halon substitutes such as FM200® and NAF S III. It was recently selected after stringent comparative testing by the US Department of Defense Halon Depletion Agency for purchase who verified its accuracy to +/-1.5 mm. It is supplied with many units to fire service companies, offshore installations and utility companies worldwide for this purpose.
2.    Marine Multi Banked Cylinders:
Using the multi-bank cylinder rod, the liquid level indicator can also verify levels of extinguishing agents in multi-banked cylinder rows using this extension rod to reach the second and third rows. This type of installation is typically found on board ships and we have extensive experience of supplying this equipment to the marine sector. There are some dedicated marine units are available in the market as well.
3.    LPG:
Propane and Butane may be tested though the unit will function in reverse. It depends how qualified ultrasonic product you have purchased.
