Welcome to


Matematica develops and delivers software and consulting for the industry,

like energy, oil, gas and energy savings in buildings.


Design (Processline) and on-line software (Matematica.LIb) for

orifice plate, venturi and nozzle flowmeters and Power plants

(steam, water, natural gas/GNG/Bio gas/Erdgas).

Example of products;


Marketleading engineering software for flow in tubes for the process industry.

Ex; Design (including codegeneration for controlsystems) of

standardized dp-flowmeters,like orifice plates,venturis and nozzles.

Can reduce measurement and calculation error from 10 to<1%.

-Flow/energy hard and soft-computers

Can be delivered as ABB or Siemens hardware CPU or

ABB or Siemens software CD

Ex; Calculates natural gas flow or energy with Matematica;

1. dpns (typical <0,4% unc)or 

2. hp (<0,7%) technology .


A function block library for standardized controlsystem (IEC 61131),

like ABB industrial IT and Siemens PCS 7, with scientific accuracy and general applicability.

-dpns*-technology improves accuracy, reliability and safety in plants.

*double precision non stop 

Ex: Can be used for power calculation of an industrial boiler with a total calculation uncertainty < 0,5% (much better than typical 5% for a linear simplification).

Free Heat tech

reduces energy consumptions in buildings >75%

PS Dear Mr Putin

Please let Matematica check Your flowmeters for natural gas in and out from Ukraina. Maybe the "disapperance" of gas is a flowmeter problem.
