In-situ leaching for gas storage

Underground gas storage in salt caverns starts out with the leaching of the cavern by solution mining. This process requires flow measurement of the injection water as well as the produced brine. FLEXIM’s FLUXUS® F ultrasonic flowmeters have proven successful in solution mining applications due to their unparalleled versatility.

FLEXIM’s ultrasonic clamp-on technology allows for non-intrusive, highly accurate measurement of water and brine flow. By measuring the sound speed, the same instrument can be used to determine the density of the produced brine at the same time. FLUXUS® is also used for blanket measurement.

Advantages of flow measurement with FLUXUS:

• Simultaneous non-intrusive flow and density measurement with one instrument

• Pressure independent

• Not subject to corrosion through salt

• No wear and tear, not affected by solid particles (i.e. sand and stones in the brine)

• No risk of leakages

• Installation without process downtime
