UK ultrasonic density meter specialists for over 50 years

Independent UK expertise

Rhosonics support from application review to long-term service

Since 1971, PMA has helped UK and international process operators solve demanding online measurement challenges. We start with the process objective: what must be measured, where the measurement should be made, and how the signal will support safer, more stable or more efficient operation.

For Rhosonics projects, we review the liquid or slurry, pipework, access, operating conditions and control-system requirements before recommending a solution. That application-led approach continues through installation planning, commissioning, training and ongoing technical support.

Why work with PMA

Specialist support built around the measurement application

More than five decades of process measurement

PMA’s experience extends across online analysers and industrial measurement techniques. That broader process perspective helps us examine the measurement point, installation and operating objective rather than treating the instrument in isolation.

Application-led instrument selection

We review the process medium, concentration range, pipework, installation conditions and required outputs before matching a Rhosonics ultrasonic density or concentration analyser to the application.

Installation and commissioning support

Our team can support installation planning, commissioning, operator familiarisation and documentation so that the measurement is introduced with clear responsibilities and an agreed verification path.

Confidential and dependable project support

We work carefully with customer process information and can support appropriate confidentiality requirements. Clear communication and long-term technical assistance remain part of the relationship after delivery.

Measurement in context

Where ultrasonic density measurement adds value

Rhosonics ultrasonic analysers provide continuous, non-nuclear density or concentration measurement for suitable liquids and slurries. Applications can include mining and mineral processing, dredging, cement production and other process environments where a representative online trend can support informed operational decisions.

PMA helps define the measurement objective, select an appropriate location and plan how the analyser will be checked against process or laboratory evidence. We also support the practical details that influence a successful installation.
