Zusammenfassung:	PURPOSE:To effect on accurate and very simple measurement of liquid level. CONSTITUTION:A pressure detection sensor PA is placed in a liquid material and measures the pressure P1 at the placed position. Also a differential pressure detection sensor PB is placed in liquid at a depth deeper by DELTAx than the pressure detection sensor PA and detects the differential pressure P2 between DELTAx in the liquidus body. Based on the pressure P1 and P2 detected with these sensors, the liquid level is measured. The liquid level is given by the operation of DELTAxXP1/P2.
