The Model BSIL-W10-A Liquid Level System consists of a series of vessels containing liquid level sensors interconnected by a liquid filled tube. A reference vessel is positioned at a stable location with observation vessels positioned at different locations at approximately the same elevation. It is suitable for settlement monitoring, including road/railway subgrades, bridges, tunnels, dams, foundation pits,building foundations.
The BSIL-W10-A Liquid Level Sensor is based on Vibrating Wire Sensor which is particularly suitable for critical situations where high resolution is required. Settlements as small as 0.01 mm are detectable.
◆Accurate and precise measurements using Vibrating Wire sensors
◆Very high resolution
◆Robust design and reliable
◆In-built temperature compensation

Temperature Range： -20 to + 80°C
This system is particularly suitable for critical situations where high resolution is required.
A series of vessels are interconnected by a liquid-filled tube. One reference vessel is located on stable ground and the other vessels are located at the points of settlement. Each vessel contains a cylindrical weight suspended from a vibrating wire transducer.
The common liquid level inside each vessel partially submerges the hanging weights; settlement of a vessel causes an apparent rise of the water level in that vessel leading to a greater buoyancy force on the weight and a reduction in the tension and frequency of the vibrating wire.
