Flow meter model 850 EWO Flow meter

The flow meter type 850 works according to the approved calorimetric measuring principle: In this process a heated sensor is cooled down by the gas circulating around it. The flowdependent cooling-down is used as a measuring effect while the degree of cooling-down is directly depending on the passing air resp. gas mass. Therefore, an additional pressure and temperature compensation is not necessary. Unlike conventional bridge circuits, the newly developed evaluation electronics system captures all measurement values digitally. This facilitates very precise and fast measurements.
