WEIR MONITOR VWM-2000
The Geosense® VWM-2000 vibrating wire precision water level monitor utilises a vented vibrating wire force transducer in combination with a cylindrical weight suspended from it to monitor water levels.
The vibrating wire transducer is vented to atmosphere so that any atmospheric changes are automatically compensated.
Description
The transducer and weight are contained within a PVC slotted pipe which can be located within the weir or tank as necessary and the vent tube is terminated within a moisture trap. Periodic change of the desiccant is required.
The cylindrical weight is partially suspended in the water level being monitored and as the water level changes the force on the transducer by the cylinder alters which in turn alters the tension of the vibrating wire.
As with all vibrating wire sensors, the output is frequency and therefore not affected by changes of cable resistance and therefore extremely long cable lengths are possible.

MEMS Tilt Beams are designed for attachment to structures, on either a vertical or horizontal surface, for the measurement of tilt or differential settlement.
They consist of a highly accurate MEMS sensor housed in a fully sealed enclosure which is mounted on a lightweight rigid GRP beam. This can be mounted onto the structure using special anchors. The GRP beam has a very low coefficient of thermal expansion meaning that thermal affects are minimised.
