Aquip recently worked with Aeris Resources Ltd to help the team at Tritton Copper Mine in New South Wales with their need to measure the flow rate of paste fill slurry compromising cement, tailings and water.
To give you an idea of the task at hand, the solids content of the slurry we were working with was above 70 per cent, with particle sizes of less than 20µm, while the DN200 HDPE pipe had a wall thickness of 22mm and was located more than a kilometre underground.
Here, we look at the challenges we faced, our tailored solution and any considerations that should be made before embarking on a project like this.
The project has come about as a result of the common challenges faced by operators when attempting to measure the flow of slurry. Using the Flexim clamp-on ultrasonic technology with over-sized transducers, we were able to negate these issues:
All of the above challenges were addressed in the decision-making process, with the ultrasonic flow meter solution meeting the needs of the client.
When carrying out ultrasonic flow measurements, it’s important to note that there are a number of factors that can cause challenges or prevent readings from being picked up. We attempted to replicate results on a Schedule 80 ERW Grade B steel pipe carrying the same slurry and experienced some difficulty in obtaining measurements. Contributing factors to this outcome may have included:
Prior to supplying a rental unit or quoting for a new Ultrasonic system, our technical team reviews client application parameters to ensure recommendations are suitable and success is optimised.
For particularly challenging applications, our personnel are available to assist on-site, testing a range of options to ensure the system provided meets the application needs.
