         The test rig can be used to:

         • Study the pressure drops caused by straight lengths and   BDF/3100  Version with 7 pipes
         singularities.

         • Compare various methods of measuring flowrates.

         The  up  stream  valves  on  each  line,  allows  to  select  the
         singularities to study.

         The fast two-way shutoff couplings disposed on the entire
         bench allow the pressure loss measurement.

         The  measurements  are  done  by  connecting  the  pressure
         tap hoses of the differential pressure transmitter (for low
         pressure drop) to the terminals of the element to be stud-
         ied.

         A device to inject a tracer allows to visualize the different
         flow regimes in the pipes.
