The Hydreka range of gauges are designed for the precise measurement of internal pipe diameters from a simple tap.
This measurement allows for the exact positioning of the HydrINS2 insertion electromagnetic flowmeters in the center of the pipes.
The instrument can however be used independently of these products to measure the real internal diameters of pipes.
In many cases, especially in older pipes, the internal diameter may differ significantly from the initial diameter due to corrosion and various deposits over time (rust tubers, scale...).
Even for new pipes or pipes with little risk of deposits, the exact specifications of the pipes may be unknown (composition and thickness of the coating).
However, precise knowledge of this diameter is necessary in particular for the operation of flowmeters in full pipes, to convert the measured velocities into flow rates (electromagnetic flowmeters, ultrasonic flowmeters...).
Hydreka gauges use an original system of stops and locating rings. They are very easy to use and can be used on pressurized pipes, without stopping the flow.
