ULM-11A1 Level Transmitter

Ask a question

A noncontact radar level transmitter ULM-11A1 aims to resolve common process tasks of level measurement in various tanks containing liquids or loose materials. No contact between the ULM-11A1 level transmitter and the product to be measured makes this instrument perfect for level measurement of most explosive, food, and high-viscosity products, either neutral or aggressive. It combines an optimal price, high reliability, and measurement accuracy.

Explosion-proof design – 1ExdIIBT6.


 

Technologies. ULM-11A1 level transmitter as well as ULM-11 and ULM-31А1 level transmitters use an original technology of adaptive FMCW-system tuning; therefore the ULM-11A1 level transmitter is equally reliable in level measurement both for liquids and various loose materials. The used technologies ensure maximum sensitivity in level measurement of various products.

Applications. The ULM-11A1 level transmitter is used to measure the level of acid (sulphuric, hydrochloric, nitric, hydrofluoric, etc.), alkalis, water, various solutions, chemicals, petroleum, dark and light oil products, mazut, bitumen, alcohol, gas condensate, cement, ore, crushed stone, sand, coal, coal dust, chips, wood sander dust, soot (carbon black), etc.

Unified design. The ULM-11A1 level transmitter has a unified structural design. The ULM-11A1 level transmitter has the same mounting dimensions as all other ULM series level transmitters.

Compatibility. The ULM-11A1 level transmitter is fully compatible with all other ULM series level transmitters both by their protocol and electrical connection. This allows the Customer to build a level measuring system on the enterprise's tank farm with the best price/quality ratio. Depending on the required measurement accuracy, each specific tank can use different level transmitters. Herewith, all level transmitters are connected to a single information line and work with the same top-level software, which eventually enables the Customer to obtain the best optimal price/quality ratio of the level measuring system.
