Components and assemblies are often tested in cold chambers at temperatures down to –40°C. This company can equip its Volumeter flowmeter (photo) with electronic sensors that are suitable for such low temperatures upon request. The upper temperature limit is 200°C. For even measurements in extreme cold, the special advantages of the device’s “screw” measuring method offers advantages over other methods, such as gear or Coriolis. In particular, the Volumeter offers a high measuring precision (±0.1% of the measured value) and a measuring range of 1:100. This wide measuring range makes it possible to pass through the broad characteristic curves during the functional testing of hydraulic components. — Kral AG, Lustenau, Austria
