Ultrasonic Density Probe




The ultrasonic spectroscopy technology in combination with the extremely abrasion-resistant sensor allows for the monitoring of all mineral slurries. 

Real-time slurry density monitoring when undertaken can be risky and expensive using nuclear densitometers. With the introduction of the PIQ Ultrasonic Density Probe, the density recording can now be performed in a more secure, user-friendly and highly accurate manner, saving costs and allowing for quicker interventions.

The density probe is ceramic and can determine density, specific gravity, total suspended solids and temperature of abrasive and high concentration slurries. The ceramic sensor construction not only provides the best acoustical physical properties, but also provides the highest degree of hardness ensuring optimal abrasive resistance for the demanding applications in this industry.

The analyser processes the digital signals of the ultrasonic density transmitter and Probe. It calculates the density, specific gravity, total suspended solids and temperature, and if a flow meter is connected, the Massflow as well.  There are four methods of probe installation available to match the specific application in pipes and tanks.


  • Little to no maintenance requirement due to ceramic structure of the probe
  • Lower calibration required.  With an initial good field calibration, the accuracy is about 5 g/l in the full range 1.3 SG and does not change during the lifetime of the probe.
  • Any changes in the slurry density are immediately observed, offering customers better process control.




  • No nuclear source
  • High frequency measurement to improve process control
  • Resistant to abrasive and corrosive slurries
  • Low maintenance calibration
