Level measurement using ultrasonic 'through-the-air' principles has been widely used in the process industries for many years, but it has its limitations with regard to the application. Pressurised vessels, varying gas densities and surface foam can all cause loss of the echo signal. Hycontrol's new non-contact ultrasonic instruments are capable of monitoring levels with novel 'through the wall' techniques which overcome these fundamental problems.

This enables level measurement in totally enclosed vessels without the need to enter or cut into the tank or silo. These systems can provide a wide range of control options, from single point level switching to continuous level measurement and can be installed on a wide range of applications including hazardous and aggressive media.

Advantages

• Easy to install as the sensors are fastened to the outside of the vessel or pipe and there is no interruption of the manufacturing process.
• Simple to install on existing plant.
• Ideal for aggressive, toxic, pressurised and sterile applications as there is no contact with the product.
• Measurement is possible even with foam on liquid surface.
• Suitable for all hygienic applications.
• Hazardous area certified for zones 1 & 2 (code EExmIIT6).
• Will not interfere with cleaning processes.
• Fixed installation and portable units available.
