The company has been committed to the R & D and manufacturing of pressure measuring tubes for many years. The pressure measuring tubes produced are deeply loved by the majority of merchants. Piezometric tube is an ancient and common seepage monitoring instrument. It indicates the seepage pressure by the height of water column in the tube. In the observation of hydraulic structures, piezometric tubes are often used to monitor the groundwater level, dam phreatic line, pore water pressure, seepage around the gate dam, seepage pressure at the dam foundation, uplift pressure of concrete gate dam, external water pressure of tunnel and culvert, etc.

Precautions for the use of pressure measuring pipe:

(1) During seepage pressure monitoring, the purpose shall be clear and the observation section shall be formed. The measuring points shall be specific to the specific measuring points and specific physical quantities of the dam body, dam foundation, around the dam or fault. The layout of the measuring points shall be determined according to the specifications, experience and specific projects.

(2) The construction requirements are very high, and the construction quality must be ensured. Sensitivity test and elevation review of inlet pipe and nozzle must be carried out regularly during use.

(3) Due to the increasingly important role of temperature monitoring data in seepage analysis, attention must be paid to instrument selection and measurement methods.
