Turck is now offering levelprox, a level-detection sensor designed for use with metal storage tanks. Utilising ultrasonic sensing technology, levelprox offers a clear advantage over traditional capacitive sensors with the ability to detect liquid levels inside a metal-walled tank without the need for an access port. For capacitive sensing, an access port must be present in the tank wall, which reduces the overall structural integrity of the tank itself, creating a possible leak-point as well as a potential spot for the media contained within to build-up. This same drawback exists with vibrating fork sensors.
levelprox is suitable for applications in breweries, dairies and other food or beverage production facilities, wastewater treatment, chemical handling, oil or lubricant storage and pharmaceutical. Using ultrasonic technology to sense through the metal tank walls is ideal for situations where intrusion into the tank is not desired, such as when the media is caustic or volatile, under high pressure, at very high temperatures, and especially if the process environment is sanitary. There are no material compatibility issues since there is no direct contact with the media, and it is not affected by stirring devices.
Constructed of high grade 316 stainless steel (1,4404), the device can sense through walls from 1 to 15 mm thick. A 1-1/2 Tri-clamp fitting is incorporated into the sensor and can be used with the optional mounting kit, which includes the clamp. The mount is welded to the tank and the sensor is fastened to it with the Tri-clamp. This positions the sensor face in the ideal detection position and also ensures a sanitary, leak-proof fitting. levelprox is self-contained with no need for an additional amplifier.
The product includes a teach button for simple set-up and programming. Once the teach mode is entered, the sensor is 'shown' both the full and empty conditions. Upon completing set-up, the sensor will automatically return to the 'run' mode and the values will be stored. If the teach procedure fails, an alarm output is activated to inform the user of the problem.
levelprox also features DIP switches for toggling a variety of application parameters such as normally open/normally closed, time delays and disabling the teach button.

Level Measurement & Control
Ferric chloride and other acids are essential chemical substances in water and wastewater treatment. To control the dosing of acid solutions, an Australian wastewater treatment plant uses a special container to store, mix and add these chemicals. The company opted in favour of KROHNE’s OPTIWAVE 1540 radar level transmitter

Level Measurement & Control
A municipal utility in eastern Germany operates a state-of-the-art wastewater treatment plant with sustainable sludge treatment. The ultrasonic signal was being partially deflected by the wind, leading to frequent false measurements and inefficient process workflows. The problem was solved by replaced the ultrasonic level sensor with KROHNE’s OPTIWAVE 1540 non-contact radar.
