Overview 
 UQZ-1, UQZ-2, UQZ-3 series float level gauge is used to directly indicate a variety of open or high pressure liquid container pointer instrument. The instrumentation and industrial equipment used in the glass level gauge on the comparison, it is not afraid to break a clearer indication, especially for the glass wall on the role of a viscous oil or hazardous liquid medium category of the direct instructions of the media . 
 Instrument is a pure mechanical structure, it is inflammable and explosive places in the work, with the nature of security. 
 UQZ-1 and UQZ-3 series float level gauge for the top-mounted instruments, can be used in containers such as underground oil storage tank or level indication. 
 UQZ-2 series of float level gauge has a strong anti-vibration capabilities, can be used for mobile devices, such as tank cars and other installation. The instrument of the indicators are in line with February 1981 issued by the former State Bureau of Labor LPG tankers ≤ ≥ safety regulations requirements concerning the level gauge. 
 UQZ-1, -2, -3 series type instrument not adapted to the brass, aluminum, stainless steel and other materials have a strong corrosive effect of the media.
