Low-Cost Sensors to Measure the Flow, Pressure, and Density of Slurry

Request Number N668697
Need details
Description

We are looking for low-cost sensor technologies to measure flow, pressure and densities of slurry at both the inlet and outlet of a centrifugal pump, regardless of slurry type (i.e. iron, copper, sand, salt, etc.). 

 

Ideally, we would like to see a single sensor with the ability to measure each of these parameters simultaneously.  While our main objective for the sensor(s) is to monitor the slurry passing through our pumps at a mine site, we are looking for sensors that could also be adapted for other equipment such as cyclones, hoses, and pipes.

 

Background

Slurries with high viscosity are difficult to pump and can therefore result in large back pressures.  Excessive pump back pressures can lead to blockages which can, in turn, prevent successful pump processes.  Monitoring the process properties (i.e. flow, pressure, and density) of slurry is important to prevent blockage and to ensure the safe transportation of the waste.  However, reliable and accurate instrument readings are often difficult or even impossible to obtain in equipment carrying slurry due to the range of solids concentrations and changes in particle size distribution.  While process measurement sensors do exist, many of these sensors are quite costly.  As a high volume of sensors is required at each site, expensive sensors make it difficult for us to keep costs low for our customers.   

 

Key Success Criteria
  • Must be low-cost:
    • $500 USD or less per sensor that measures one parameter 
    • $2500 USD or less for sensors that can measure multiple parameters
  • Must be able to measure flow, pressure, and/or density of slurry (pressure and flow rates can vary between 1L/s to 5000 L/s, and pressures can reach 1500 kPa)
  • Must be suitable for mounting to the pump/cyclone/hose/pipe while in-situ, and therefore must be practical in terms of size and weight

 

Preferred Collaboration types
  • To Be Negotiated
