（1） Pressure guide tube thickness should be appropriate, the general inner diameter is 6 10mm, the length should be as short as possible, the maximum length should not be more than 50M, in order to reduce the delay of pressure indication. Jei didesnis nei 50 m, reikia pasirinkti manometrą, galintį perduoti didelį atstumą.
（2） When the pressure guide pipe is installed horizontally, it should be guaranteed to have a tilt of 1:10 1:20 to facilitate the discharge of the liquid (or gas) accumulated in it.
（3）Kai išmatuota terpė lengvai kondensuojasi arba užšaldoma, būtina pridėti šilumos išsaugojimo atsekimo vamzdyną.
（4）There should be a cut-off valve between the pressure outlet and the pressure gauge to prepare for the use of maintenance pressure timing. Atjungimo{0}}vožtuvas turi būti įrengtas šalia slėgio išleidimo angos.
