There are many problems with the pressure measuring instrument when it is installed. If there is a problem with the pressure measuring instrument installed, it will cause the measurement to be unstable, and serious problems will occur. Therefore, the user needs to know the installation knowledge of the pressure measuring instrument when installing the pressure measuring instrument, which is very helpful for the user's use and installation. Today Xiao Bian has introduced the problems that need to be paid attention to when installing the pressure measuring instrument.

(1) In order to ensure that the instrument is not affected by the measured media or the viscosity is too large and crystallized, an isolation device shall be installed;

(2) In order to ensure that the instrument is not affected by drastic changes in the measured medium or pulsating pressure, install a buffer. Especially in the pressure surge and pressure drop, the pressure gauges are most likely to be damaged and scrapped, even the spring tubes crack, and leakage occurs;

(3) In order to ensure that the instrument is not affected by vibration, the pressure instrument should be equipped with vibration damping device and fixing device;

(4) In order to ensure that the instrument is not affected by the high temperature of the measured medium, an elbow device full of liquid should be installed;

(5) The special special instrument is forbidden to use, and it is forbidden to measure on the device without special and reliable equipment. It is forbidden to use a common pressure gauge for measuring the pressure of special medium.

(6) For the newly purchased pressure detection instrument, measurement verification must be performed before installation and use to prevent vibration, damage, or other factors from destroying the accuracy of the pressure instrument during transportation.
