In case of monitoring: civil buildings and monumentals; bridges and viaducts; diaphragms and reataining walls; dams and tunnels; OTR suggests high sensivity settlement system.

The system is made up by many measurement cups filled with liquid linked each other with an idraulic pipe. The measure principle is the comunicating vassel one: when there’s the subsidence of one cup the liquid goes to the other one. Measure sensors reveal the changing on the readout unit after a subsidence.

How is it installed?

For every levelmeter cup is trailed on the horizontal floor the circuit diagram using an optical spirit or water level. The positions of the cups should be marked and significants point and than fixed on the wall level meters and the cups, taking care to the positions preaviusly fixed for cable and tubes too. To fix the last ones it should be supplied collars fitted with dowels when using insulation.

To fix the cups proceed laying the levelmeter to the wall ensuring that it’s obverse and after you have to check if the tubation’s holes are horizontal.

At this point drill the wall and fix the levelmeter with dowels and laying pipe throught the cups suspendig it with steel ties.
