（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. Jika lebih dari 50m, pengukur tekanan yang dapat mentransmisikan jarak jauh harus dipilih.
（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）Ketika media yang diukur mudah untuk mengembun atau membeku, perlu untuk menambahkan pipa pelacakan pelestarian panas.
（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. Katup pemutus-off harus dipasang di dekat outlet tekanan.
