Fig. 14: Pressure loss diagram (reference air, with a 250 µm inlet
mesh filter), types 8700 / 8705
The diagram shows exemplarily the pressure loss characteristics
when air flowing through.
For determining the pressure loss with another gas first calculate the
air equivalent of the other gas.

Fig. 15: Pressure loss diagram (reference air, with a 250 µm inlet
mesh filter), types 8701 / 8703
The diagram shows exemplarily the pressure loss characteristics
when air flowing through.
Further it differentiates two designs, first one with ¼ inch connectors
and second one with connections on the bottom of the flowmeter
(used for assembly on manifolds).
For determining the pressure loss with another gas first calculate the
air equivalent of the other gas and respect the fluidics needed with
the other gas.
