Instrumentation services including design installation and maintenance of geotechnical instrumentation systems for dams and civil structures, ranging from manual hydraulic piezometers, flow and deformation devices to the latest electronic instrument systems

Instrumentation is a vital indicator of a dam's condition. Information from instrumentation is used to identify dam deterioration, developing incidents and give ongoing assurance of dam performance. Long term maintenance, refurbishment and replacement is part of managing these valuable dam safety assets.
Damwatch's instrumentation team specialise in instrumentation design and application tailored to the requirements of the customer or structure.
We can offer full lifecycle management from design and installation to maintenance, refurbishment and replacement.
Damwatch provides services for the repair of surveillance monitoring equipment. This includes routine maintenance and instrument refurbishment.
Damwatch can evaluate the performance of instruments through analysis of instrument data and/or on-site testing.
The evaluation process informs the type and frequency of instrument maintenance and potential remediation strategies.

Costs generally increase with sensitivity, resolution, repeatability, and accuracy, so it is important to specify just the performance levels that are needed. Higher performance levels do not necessarily provide more useful information.
Instrument performance is specified by range, resolution, accuracy, and precision.
- Range is defined by the highest and lowest readings the instrument is expected to produce.
- Sensitivity is the smallest change that can be sensed by a sensor. Sensitivity typically decreases as range increases.
- Resolution is the smallest change that can be displayed on a readout device. Resolution typically decreases as range increases.
- Repeatability or Precision is the degree to which a reading deviates from the mean of a series of readings taken under identical conditions.
- Accuracy is the degree to which a reading deviates from an absolute value.
Damwatch instrument specialists can review instrument designs, specifications and installations.
We provide expert advice and training for repair and maintenance of instruments, instrument reading, data collection, data processing and evaluation.
