Product Introduction

Product Introduction

The QPA02 pressure hydrostatic leveling instrument is a high-precision measuring instrument that converts the pressure value at the measuring point into the liquid level value through a pressure sensor. By calculating the change in liquid level between the reference point and the observation point, the settlement amount is derived. The entire system consists of multiple hydrostatic leveling instruments, installation brackets, liquid storage tanks, liquid tubes, gas tubes, acquisition boxes, etc. It is mainly suitable for long-term high-frequency monitoring of vertical displacement between multiple points in geotechnical and structural safety engineering.
