Alumina Refinery Case Study for Mining
We found early tests using clamp on ultrasonic flowmeters have yielded great results.
- Flow measured using a Flexim Portable F601 with special high power transducers.
- Pipe diameter 408mm steel with a wall thickness of 10.16mm.
- Fluid Temp: 70 deg C
Flow was measured within 1% of existing inline DP/Orifice flow meter
DP/Orifice plates installed provide accurate measurements however they require regular maintenance. The impulse lines have to be cleaned out and pressure transmitters tested and calibrated.
Pipes are also cleaned with Caustic every 12 months and any inline equipment is normally removed. Ultrasonic meters mounted externally will reduce downtime. The overall heath and safety, risk of subjecting workers to this environment is a major concern and the Flexim ultrasonic system is a major advantage.
