Considerations for the selection and installation of pressure transmitter pressure lead pipes

Thread Content

　　Precautions for the selection and installation of pressure transmitter pressure transfer tubes: ① Choose the appropriate diameter and length for the pressure transfer tubes; generally, the inner diameter should be between 6 and 10 mm, and the length should range from 3 to 50 meters. ② Pressure transfer tubes installed horizontally should have an inclination of (1:10) to (1:20). ③ When the medium being measured is prone to condensation or freezing, insulation and heating tubes should be installed. ④ When measuring liquid pressure, a gas collector should be installed at the highest point of the pressure transfer tube; when measuring gas pressure, a gas-liquid separator should be installed at the lowest point. When the medium may produce precipitates, a sedimentator should be installed before the instrument. 　　Installation method of the pressure transmitter pressure lead; Installation is divided into two types: direct measurement and indirect measurement. 　　Direct measurement types: side flange type; direct installation type; submersible type. The first two are the most common. 　　Indirect measurement types: double (single) flange remote type; threaded remote type; snap-ring remote type; insertion tube type. 　　The measuring pipeline should be as short as possible, with a length not exceeding 15 meters
