Abstract
PURPOSE:To carry out maintenance and check without interrupting the use of a tank and also to obtain a level measurement at high precision by providing a level measuring balance tube with an ultrasonic wave transmitter/receiver mounted on the bottom detachably on the tank through a valve. CONSTITUTION:With levels of a tank 13 and liquid 14 in a balance tube 15 kept identical by opening instrument valves 16, 17 full, an ultrasonic wave transmitter/ receiver 19 having received a signal 1MHz or so from an oscillator 17 through an amplifier 18 transmits an ultrasonic wave 20 toward the surface of the liquid and receives the reflected wave 21. From a time DELTAt from the ultrasonic wave transmitting to receiving which is detected by a time counter circuit 22 and a liquid temperature T detected by a thermocouple 16, the liquid level l2=C'(T)XDELTAt/2 is obtained through an arithmetic circuit 24, which is delivered as a level signal 25. The system is now ready for level measurement in high precision, and also for maintenance, check, repair, etc. while using the tank by detaching the balance tube 15 through closing the instrument valves 16, 17 full.
