Oriketo plant and Indmeas started a cooperation 2012 to determine and follow-up the plant's fuel energy.    

Based on the indirect measurement method the real fuel effect arriving to the plant could be determined with an accuracry of 3%. 

 "With the help of an accurate control value we have been able to improve our sampling methods and this way reach significant savings in fuel costs".    

 Ilkka Syrjälä, Turku Energia



The Fortum Bristaverket in Stockholm produces yearly 763 GWh district heating and 293 GWh electricity out of biofuel. Indmea's on-line efficiency monitoring is installed in the plant's automation system.

"Now we can estimate optimization measures in real-time, as we before had to do it retroactively by calculation.  

The on-line monitoring helps us also to make correct investment decisions".

Göran Blommé, Fortum Bristaverket



Sappi Kirkniemi in Finland manufacturers coated magazine paper with three paper machines. Indmeas has since 1997 assured the quality of the plant's key flow measurements.   

"By regular calibrations of our most important process measurements we can validate the key figures of our energy consumption.  

The calibration database works also a significant support for maintenance purposes as well as for audits of the plant's quality system".

The Syvab's Himmerfjärd purification plant treats water in a large area on the west side of Stockholm. Indmeas calibrates regularly the outgoing waste water flow measurement.   

"We report this flow value to the authorities. The collaboration has worked very well. It is important for us that we do not need to call and order to calibration each time; Indmeas calls us well before due time to plan the calibration". 

Sara Söhr, Prosessipäällikkö Syvab



Alholmens Kraft in the city of Pietarsaari is the biggest biofuel power plant in the world.

Indmeas produces the uncertainty and risk analysis for the plant's yearly CO2-emission.      

"We do not fully master the uncertainty and risk determination. Thanks to the collaboration with Indmeas we can minimize the risks for faults and can also benefit from knowledge received at other plants.

We also do not have to use time on understanding the new EU-directives and can concentrate purely on running our operation".
