NIVOLIC SG Settlement Gauge

MULTIPOINT

HIGH PRECISION

LIQUID LEVEL SYSTEM

The NIVOLIC SG is a  high precision  liquid level system designed to measure relative settlement using vibrating wire transducers.

Description

The NIVOLIC SG is a high-precision liquid level system designed to measure relative settlement in a multipoint system. It consists of a series of chambers connected together by a liquid line. In each chamber, a weight is suspended to a vibrating wire transducer.

Changes in elevation of the water level in the chamber modify the buoyancy force acting on the weight, thus modifying the resonant frequency of the vibrating wire. In the multipoint system, one of the chambers is the reference for the calculation of relative movements of all the other chambers. A thermistor is integrated in the gauge, enabling measure of temperature.
