CYJ series double bellows differential pressure level gauge, which has obtained national patents (patent numbers: ZL2276185.2 and ZL99.2.3725.2, with Chairman Mao Qingye as the chief patentee). It is mainly used for: ① liquid level measurement of cryogenic liquid containers (storage tanks and tanks), such as liquid oxygen, liquid nitrogen, liquid argon, liquid carbon dioxide, etc., and ② gas and liquid flow measurement (instantaneous). Dial diameter 1 and 152 mm two structures. The measured liquid level is ~ 1.5m (water column) ... ~ 25m (water column) and ~ 35m (water column). Considering that the misreading rate of the original dial with white characters on black background is 22%, it is not suitable to use it. Our company has made more perfect improvements in the dial and appearance. According to the regulations on the supervision and management of the license for manufacturing and repairing measuring instruments, the original production license number: Chuanzhi 1295 expired, and our company obtained a new license for manufacturing measuring instruments in June 27, with the number: Chuanzhi 373. Product implementation standard: Q/79397859-3.2-26.
