1 Condensate vessels
2 Orifice or impact pressure probe
3 Blocking valves
4 DPT10
5 Drain or blow-off valves
6 3-fold valve block
When using a 5-fold valve block, the drain or blow-off valves are
already integrated.
. Mount DPT10 below the measurement loop so that the effective
pressure lines are always filled with liquid and gas bubbles can
bubble up to the process line
. For measurements in products with solid content such as e.g.
dirty liquids, the installation of separators and drain valves is
recommended to enable collection and removal of debris and
sediment.
. Fill the effective pressure lines to the height of the condensate
vessels before setup
