Flow Calibration –
There are two typical flow standard systems to use in calibration of Isaac flow sensors.
The first is an orifice that with differing applied pressures produces multiple flow rates. The
second is a high accuracy flow element with an analog output or display. Because both are
calibrated and traceable either can be used to calibrate and Isaac.
This image is a typical flow calibration setup with a digital mass flow standard. The Isaac provides a
constant pressure and the needle valve varies the flow to make the calibration point.
