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.

The structural infrastructure must always meet requirements such as performance, stability and durability. These requirements will have a lasting effect on our mobility in the future. The corrosion risk and the corrosion activity of the reinforcing steel largely define these requirements and are determined by various impact and material parameters.
