How does the 5500 sc Silica or Phosphate measure the flow rate into the analyser?
5500 sc measurement details.
The 5500 sc analyser uses a pressure differential technique to calculate the flow rate into the analyser. The tubing length and characteristics of the tubing and heating coil are known and used in the calculation of the sample flow rate. This is why sample pressure must be in a specific range of approximately 2.5 psi.
