Optimise Production

The density of slurries is measured to support the operator to control and enhance the production. Traditionally this is done with gamma meters. The radioactive source however is the cause of a lot of practical drawbacks with regards to licenses, training, shipment and operators who have their reservations about using such technology. Furthermore it has an impact on the business management of companies who have to answer to society’s pressure to reduce nuclear waste, and to operate in a sustainable manner.

The Alia Density Meter is an electromechanical alternative without these drawbacks. It offers a quick and accurate measurement of the density of slurries. It can be easily combined, e.g. with existing flow meters and control systems.

Working Principle

The meter’s design is as straightforward as possible: an in-line density meter that is robust and exceptionally easy to install and use. The design makes use of Newton’s second law of gravity to determine the mass of the slurry, while the volume is a known factor in the meter. This means that the output data is immediate and accurate regardless of pipe diameter or slurry composition.

In order to yield accurate results, all non-gravitational forces working on the device are mitigated. In particular, to overcome arduous process conditions for example, a dredger rolling on ocean waves, or pipes vibrating under high pressure pumps an accelerometer is implemented, which can calculate and neutralize any interfering forces simultaneously
