Notes:
1. Initial warm-up time for signal conditioned circuitry is 1 minute max.
2. Output Voltage is ratiometric to supply voltage.
3. Temperature shifts when sensing differential pressure correlates to the density change of the gas over temperature. (See Application Note 1.)
4. Maximum allowable rate of flow change to prevent damage: 5 SLPM/1 sec.
MOUNTING DIMENSIONS (for reference only)
Note: Positive flow direction is defined as proceeding from
Port 1 (P1) to Port 2 (P2) and results in positive output. Do not
exert a force greater than 4.54kg (10 lbs.) in any direction.
