In the water and wastewater industry, pressure transducers can be installed under pressure using “hot tapping” techniques to provide a branch connection to a live pipe. This allows a pipe to be in constant operation where a shutdown would not be practical. Live pressure-tapping points can be installed on iron, steel and plastic pipes having external diameters ranging from 80mm to 600mm and carrying fluids at pressures of up to 16 barg.
The pressure and flow data can be recorded and stored for retrieval either via continuous data stream to a centralised source or via a download from an instrument logging facility. The latter avoids the need for cabling or telemetry. The availability of in built logger timers can also allow an engineer to return to site to retrieve the recorded data and so removes the need for a continual onsite presence.
All site engineers are fully qualified to work offshore and have passed the O.P.I.T.O approved Basic Offshore Safety Induction and Emergency Training (BOSIET) course. They also have a full offshore medical certificate in accordance with Oil and Gas UK medical guidelines.
