CAUTION Before starting the system, remove the caps and add water or antifreeze if necessary to
completely ll the pots and cold legs. Air trapped in the lines will produce errors in dif-
ferential pressure measurements.
Installation Procedure—Remote Mount to Orice Meter or Cone Meter
A Scanner 2000 can be mounted remotely and connected to an orice meter or cone meter with tubing for
steam measurement. The setup of the meter run and plumbing congurations can vary widely, depending
upon the challenges existing on location.
WARNING HAZARDOUS AREA USE. The Scanner 2000 is certied for hazardous area use only when

temperatures
Hot legs, insulated to within 1 ft of condensate pot
(1/2 in. diameter recommended)
MVT vent (use for
