It goes a little too far to call our technology magical, but we will come a long way. However, our technology allows for six advantages that will benefit you. The ultrasonic based density analyzer with chemically inert and wear resistant probe allows you to work safer, save money and save time.


Technology benefits




“The better choice for all users of any discipline”

Arenal developed Ultrasonic spectroscopy, a combination of the measurement of acoustical physical properties and ultrasonic spectroscopy. With ultrasonic waves, the density, specific gravity, total suspended solids and temperature are determined accurately and real-time. This technology replaces directly all nuclear density meters in the field and offers customers a higher accuracy, lower maintenance, easier mounting, lower investment cost, less maintenance, by far less administration time and costs, faster delivery times and a safe choice for the environment.


Maintenance free

“No maintenance due to sensor design and materials”

Arenal is the first and only supplier in the world of ceramic ultrasonic sensors for real-time slurry density control. As the sensors are made from the hardest ceramic on earth, silicon carbide, there is no maintenance requirement.





“No local pipe redesign needed”

Arenal offers various Slurry Density Monitoring solutions in pipes.

Our spool piece solutions are made according to your pipe and flange specifications. Arenal supplies a PU lining in pipes above 8”. The sensor is mounted to the spool with a saddle type flange. For any situation Arenal offers mounting solutions, so that local piping redesign is not needed.



Drill free & accurate

“No frequent calibration”

The combination of the measurement of different physical acoustical properties makes sure that drift in the density range from 0 to 3500 is physically not possible. However, the sensor is sensitive for temperature variations and therefor the temperature is recorded accurately for compensation.



Immediate response

“Optimized process control”

The probe and electronics are designed in such way that the repeatability and sensitivity is very high. 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. Furthermore, the responsetime is 1 second, so changes in the slurry density are observed immediately. These properties offer customers better process control.




“Check the settling process”

Arenal offers sensors for submersed mounting in tanks or vessels. It can be used manually or with an automated process winge. This offers the user to check the efficiency of the settling process and the requirement of extra or less additives.
