<P>PROBLEM TO BE SOLVED: To provide a differential pressure type liquid level detector capable of preventing complication of a constitution. <P>SOLUTION: A differential pressure type liquid level detector 1 detecting a liquid level in a tank 10 on the basis of differential pressure includes: a first diaphragm 21 installed in an upper section in the tank 10; a second diaphragm 22 installed in a lower section in the tank 10; a first pressure guide section 31 for guiding pressure P1' according to pressure P1 received by the first diaphragm 21 to the outside of the tank 10; a second pressure guide section 32 for guiding pressure P3' according to pressure P3 received by the second diaphragm 22 to the outside of the tank 10; and a differential pressure gauge 50 installed in an upper section outside the tank 10 to detect a difference between pressure guided by each of the first pressure guide section 31 and the second pressure guide section 32. <P>COPYRIGHT: (C)2013,JPO&INPIT |
