Valmet launches new microwave total solids measurement for municipal and industrial wastewater


Valmet launches a completely redesigned Valmet Total Solids Measurement – Valmet TS (patent pending) for municipal and industrial wastewater treatment plants. Valmet Total Solids Measurements have gained an excellent reputation in wastewater treatment plants around the world for solids pumping control, thickening, digesting, dewatering and dry cake applications.

Now with the latest technology and materials, the new Valmet Total Solids Measurement is set to continue being the industry leader in microwave total solids measurements. New digital electronics replace the previous analog design which, together with the new Direct Sweep Detection measurement technology, further improves measurement sensitivity and accuracy with much higher resolution than earlier.

“The new measurement is a leap forward in terms of performance and usability. We have had outstanding success in wastewater industry with close to 2,000 measurements installed, which we can now build on as well as extending our efforts to industrial wastewater applications,” says Marko Heikkinen, Product Manager, Automation business line, Valmet.

New applications

The Valmet TS flow through sensor, totally interchangeable with earlier installations, is available in standard version with various sizes from 50 to 300 mm and high-pressure versions from 100 to 200 mm. For larger diameter pipelines a new Twin Blade sensor is available.

The new measurement is insensitive to component aging or temperature effects and can now be used in the much higher conductivity environment of industrial wastewater treatment. All sensor models are also Ex certified, expanding the areas of application considerably. A special non-stick lining provides increased resistance to contaminate build-up and helps to provide a maintenance-free installation.

Easy to use

Valmet TS utilizes microwave technology to determine total organic and inorganic solids content in the range of 0 to 50 percent. The single point calibration takes only a few minutes with an integrated pressure measurement providing the possibility to compensate for bubbles.

Commissioning and calibration are now enhanced with the Valmet Bridge user interface, a touch screen control unit designed for use with Valmet measurements. With comprehensive diagnostics and Industrial Internet ready capabilities, the new user interface provides an easy-to-learn and intuitive access to measurement operation and remote services from Valmet.
