Water Pipe-aided Structural Settlement Measuring System

These measure the effect of settlement on structures during or after construction, such as the construction of tunnels directly beneath or neighboring existing structures, or preconstruction excavation. These systems consist of a reference cistern and detector, with the point where structural settlement has no effect on the reference point as the reference point. The detector is installed at the structural measurement point where settlement is predicted and connected to the reference cistern with a conduit pipe in order to measure the water level difference between reference cistern and detector. Rated capacity: ±20 mm
