Technical Description Both very large and very small water contents can be determined with precision by means of the two-stage process. For the direct determination of high water contents of x = 0.5 and below the separating calorimeter is used. High vapour contents between approx. x = 0.95 and x = 1.0 can be determined indirectly using the throttling calorimeter. The vapour is adiabatically expanded and transferred to superheated steam. The quality can then be determined with the aid of the h-s diagram. A supply of mains electricity and water are required for the operation of the unit. Steam up to max. 10bar and 240°C can be investigated.....
