The Vibrating Wire Piezometer is fabricated from stainless steel components, selected to minimise thermal effects, and electron beam that is welded together to ensure a hermetically sealed cavity for Vibrating Wire element. The Model 1200 is suitable for long term Application in embankment and borehole monitoring. The unit can be read conveniently by most common Vibrating Wire readouts and loggers.
