A new line of sonic level detectors from Ramsey – A Thermo Electron Co., Minneapolis, Minnesota, U.S., are designed to work more efficiently on a wider variety of products. With vertical technology, the sonic level detectors SonaTech and SonaMaster use lower frequencies suited for long distances, penetrating dust and eliminating the need for aiming kits. As with all sonics, the SonaTech and SonaMaster can sometimes lose an echo, in which case the detectors continue increasing the sound amplification until they find the level. The resulting accuracy and reliability make the detectors user-friendly and dependable.
