STP/NTP tutorial
Standardized flow references define the temperature and pressure conditions used to calculate flow readings. This allows flows measured under different conditions to be expressed according to a common standard, keeping readings accurate and comparable.
Changing the standardized conditions (STP/NTP) is easy to do yourself. The tutorial below explains how to configure STP/NTP settings for your Alicat mass flow meter or controller.
