Vibrating Wire Piezometer

Explanation

VW piezometers convert the water pressure in the diaphragm to be measured into an equivalent frequency signal. The pressure on the diaphragm changed by the fluid pressure causes a change in the tension of the wire. The excited wire vibrates at its resonant frequency.

Special stainless steel is used to minimize the thermal zero shift in frequency, in addition, the sensitivity of the diaphragm is quite high.

In addition, the pressure transducer is equipped with a lightning protection to protect the sensor from electric shock and a temperature device to compensate for temperature changes.

Applications

VW piezometers are designed to measure pore water and fluid pressure, which are important parameters for many structures such as pressure tanks, pipelines, drilling, foundations and dams.

• Measuring the effects of drainage systems used in excavations.
• Measuring pore water pressure to determine factor of safety under excavation or shoulder.
• Water level measurement to check performance in rivers, reservoirs, steep pipes.
• Measuring pore water pressure to determine slope stability.
• Measuring groundwater flows and seepages in embankments, dams and artificial lakes.

Features

• It is not affected by cable length and resistance change, its repeatability is very excellent
• Optimal design
• Automatic measurement possibility

Models

Standard

The Standard Model VW piezometer is designed for embedment in earth embankments and concrete interfaces, or for installation in boreholes and small diameter pipes.

Heavy Duty Type

The Heavy Duty Type Model is specially manufactured for use where semi-permanent measurement is required, such as the dam site. Aramid fiber is covered with a highly durable and 7 mm diameter PU sheathed cable.
