VIBRATING WIRE UPLIFT PRESSURE SYSTEM Model EPU-20V

Description

EPU-20V is specially designed for monitoring uplift pressure of water in the foundation of dams and concrete structures. To measure uplift pressure, it uses a vibrating wire pressure sensor. It is designed for monitoring the uplift pressure of water in the foundation of dams and concrete structures. The sensor is similar to EPP-30V, except that instead of a filter, a 25 mm BSP adaptor is provided for the connection of a pipe. EPU-20V is mounted through valves and fittings on top of the perforated/non-perforated pipe which is inserted in a borehole.
