The signal processing of sensor signal is done by digital electronics with 6bit analog digital converter. Consequently it is possible to conduct an active compensation and the transmitters with excellent maesurements and exeptionally attractive price to offer on the market. Preferred areas of use are DMP i / DMP i Laboratory Techniques Energy production (gas consumption and thermal energy measurement) Preferred areas of use are LMP i Chemical / petrochemical industry Environmental Engineering (water / sewage / recycling)
