BYYU type pressure gauge

BYYu type pressure gaugeWhen using, the U-shaped differential pressure gauge must be hung vertically on the wall or support, and then the working fluid (mercury or colored pure water) should be injected into the U-shaped glass tube according to the pressure of the measured object, with an injection amount of up to 1/2 of the scale mark.


BYYu type pressure gaugeNote 1: Before measurement, it is necessary to ensure that the maximum reading of all pressure gauges is greater than or equal to the measured pressure to prevent the working fluid from rushing out of the glass tube mouth. 2. It is necessary to maintain the purity and purity of the inner wall of the glass tube and the working fluid. When not in use, the tube mouth should be covered with gauze or other coverings to avoid affecting the accuracy of measurement and positioning.
