Glass U-shaped pressure gauge

YYU typeGlass U-shaped pressure gaugeIt is a simple liquid column pressure measuring instrument. It is a glass tube bent into a U-shape, into which a working liquid (such as water) is injected at half the height, and a scale is installed between the two vertical pipes of the U-shaped tube. When in use, connect one end of the U-shaped tube to the container to be measured with a rubber tube, and open the other end to the atmosphere. Determine the pressure of the measured gas based on the liquid column difference between the two vertical pipes. The accuracy is level 2.5.

YYU glass U-shaped pressure gaugeScope of application: Used to measure the pressure of various gases. When using water as the working fluid, the measurement range is generally between 1-16KPa. The commonly used specification is 5KPa. 10KPa。

YYU typeGlass U-shaped pressure gaugePrinciple of use: Before the U-shaped pressure gauge is connected to the pressure measuring point, the liquid levels on both sides of the U-shaped glass tube are level at the zero mark. When one end of the U-shaped tube is connected to the pressure measuring point, the liquid level inside the U-shaped tube will change. If the liquid level on the side connected to the pressure measuring point drops, it indicates that the pressure at the pressure measuring point is positive pressure, otherwise it is negative pressure.

Our factory widely adopts domestic and foreign technologies, through digestion and absorption, independent innovation, and long-term professional production of classic pressure measuring instruments - inclined micro pressure gauges, inclined tube micro pressure gauges, U-shaped pressure gauges. Used to measure the positive and negative pressure or pressure difference of various gases. There are four main product series: Yaya series inclined tube micro pressure gauge; YYX-10A (formerly TH-130 type) inclined micro pressure gauge, YYU series U-shaped pressure gauge; Red working fluid (inclined tube micro pressure gauge). The instrument is precise, reliable, convenient, durable, aesthetically pleasing, and cost-effective. All have been selected as qualified by the provincial technical supervision department and comply with the national jjG172-94 and JJG54O-88 standards.
