CGEO-WP Vibrating Wire Piezometer

Product Detail

Description

CGEO-WP series piezometers are designed for embedding in hydraulic structures and bedrock, or installing in piezometer tubes, boreholes, dams, pipelines, or pressure vessels to measure pore water pressure or liquid level. The main components are made of special steel, making them suitable for various harsh environments. The standard filter is made of sintered stainless steel with 50-micron pores, ensuring excellent permeability. The unique stability compensation technology gives the sensor a minimal temperature compensation coefficient. With improved cable protection measures, it can be directly embedded in roller-compacted concrete, where high demands are placed on the instrument.

Applications

Landslides

Slope sites

Tailings lagoons

Aquifers

Dams

Embankments

Monitoring of up-lift pressure

Measurement of ground water

Dewatering activities

Operation

Connect the sensor to the readout, terminal box, or datalogger via the cable. The readout displays frequency units, or engineering units by inputting the instrument calibration coefficient.

Features
