DEVICE FOR MEASUREMENT OF LIQUID METAL LEVEL |
摘要 |
FIELD: control systems of technological processes; measurement of levels of various media. SUBSTANCE: electromagnetic oscillations of two different fixed frequencies are generated by oscillations 1 and 2. Oscillations through receiving-transmitting antennas 9 and 10 are radiated towards controlled medium. A part of oscillations from oscillators is directed with the help of T-pieces 3 and 4 to devices 5 and 6 for measuring the phase difference. Reflected signals through antennas 9 and 10 arrive at couplers 7 and 8 and to devices for measuring the phase difference. EFFECT: higher efficiency. 2 dwgr
