High quality drinking water is a valuable resource. Managing this essential asset requires precision instrumentation across the entirety of the drinking water network. This article will explore the key challenges faced by those in water management industries and explore solutions to relevant concerns.
Challenges in Drinking Water Management
Limited space in bore holes
17.5mm diameter construction reduces the size of bore holes required minimising drilling costs for water extraction. The stiffness of titanium allows narrow body construction without compromising performance or stability. High quality screened cable and 4-20 mA signals are mechanically robust and immune from electro-magnetic interference from electric motors on pumps.
Large surface areas require the highest levels of accuracy
Many new dam constructions have shallow slopes making vertical line of sight technology very expensive to install. TERPS technology allows accurate measurements better than 0.01% (1mm in 10m depth) to allow the most efficient resource management of reservoirs.
Monitor subtle changes over long periods of time
Excellent long term stability allows drinking water systems to be accurately monitored. This enables small changes in pressure profiles, caused by leakage, to be quickly seen and located. This can be used to reduce leakage and repair costs.
Compatibility with treatment chemicals
Titanium and stainless steel construction married to cables made of polyurethane or Hytrel enable the best materials to be selected for compatibility with water treatment chemicals. This becomes particularly important in dosing stations or storage tanks where the concentrations can be high.
Difficult to access for repair or calibration
High stability silicon sensing elements in robust packaging ensures accurate and reliable performance over long periods, reducing site visits for the repair of faulty components and extending calibration periods.
Inaccessible locations, inspection chambers
Small size, fully welded construction and IP68 to 700m cable connections mean that BHGE products give reliable operation in sub surface application that are prone to flooding. Particularly useful is this feature in differential sensors for use on filters or valves.
