PRESSURE-TYPE
SETTLEMENT METER
Measuring settlement of structures
DVP-100A, DVP-100B  
(Level 160mm) (Level 500 - 3000mm)  


DVP-100A


DVP-100B

This meter utilizes the principle of “leveling.” By connecting a reference unit (water tank) installed on a horizontal surface steady point outside the area affected by the work to the object of measurement (or measuring point) by a communicating hose, the minute pressure change due to the difference of water levels between the reference water level and the settlement meter water level is detected by a differential transformer. Together with the inclinometer, this is an indispensable detector for measuring changes in the condition of existing structures incident to overpass construction work or to work in close proximity.
Moreover, since it is an extremely high precision pressure meter, it can be applied to measuring water levels or liquid levels by utilizing the pressure chamber shape and installation method.
