Notes:
1. Response time is typically 1 msec from 10 to 90%.
2. Repeatability & Hysteresis tolerances reflect inherent inaccuracies of the measurement equipment.
3. Maximum allowable rate of flow change to prevent damage: 5.0 SLPM/1.0 sec.

Amplified Sensors Unamplified Sensors
Note: Positive flow direction is defined as proceeding from
Port 1 (P1) to Port 2 (P2), and results in positive output.
