Valmet TS – reliable total solids measurement system for waste water plants

For more than ten years Valmet’s microwavebased solid content transmitters have been used in the process industry for highly demanding applications. Valmet TS has been developed from third generation microwave solids transmitters, combining cost-efficiency with the extreme accuracy of microwave technology. The new transmitter meets the needs of wastewater treatment plants – with no compromises in accuracy. The 500 references in global waste water industry speak for the excellence.
