Coltraco Limited, UK has always facilitated people with various ultrasonic instrumentations and monitoring equipment. Most importantly, they have dominated its respective market in regards to the competitive ultrasonic liquid level indicator prices they offer. Multiple options are available for people in accordance to the budget as well as requirement. This makes the customers all around the world to demand the products they are dealing in.

The Portalevel® Standard 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 of Coltraco is regarded for producing this liquid level indicator is about introducing better ways of measuring cylinders.

Applications of Ultrasonic Level Indicator
The Portalevel® Standard is a versatile instrument that can locate the level of any liquid in any single skinned container of wall thickness 2 – 15 mm. Wall thickness of 15 mm – 90 mm 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, approx 5 ft high, 10ins diameter, 45 kg or pressed steel with welded seams with low pressure fills of varying sizes and fill weights:

1. Fire Extinguishant Cylinders – its primary application is to check levels of liquid gaseous extinguishants 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 Defence Halon Depletion Agency for purchase who verified its accuracy to +/- 1.5 mm. We supply 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 Portalevel Standard ® can also verify levels of extinguishants 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. We also have a dedicated marine unit available, known as the Portamarine™, details available on request or at official liquid level indicator page.
3. LPG – Propane and Butane may be tested though the unit will function in reverse. Details explained in Operating Instructions or available on request at Coltraco Customer Support
