（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. Ja garums pārsniedz 50 m, jāizvēlas manometrs, kas var pārraidīt lielu attālumu.
（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）Ja izmērīto vidi ir viegli kondensēt vai sasaldēt, ir jāpievieno siltuma saglabāšanas izsekošanas cauruļvads.
（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. Nogriešanas vārsts-jāuzstāda netālu no spiediena izejas.
