ET 805.50 Throttling Calorimeter Show data sheet (pdf file) Print page
Technical Description

  Both very large and very small water contents of steam 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 low and high water contents can then be determined with the aid of the h-s diagram.

  Steam up to max. 10bar and 240C can be investigated.
