Notes:
1. Denotes ±(1.5% Reading+0.5% Full Scale). To obtain accurate flow measurement, let the sensor warm up 1 minute at power up.
2. The response time is determined by ADC Sampling rate and data process algorithm. The default response time is 65 ms. It can be programmed via RS232 communication.
3. The maximum pressure drop is measured at flow rate 1000 sccm. For 500 sccm flow sensors, the pressure drop will be smaller. For 30, 100 and 200 sccm flow sensors, the flow pipe will be smaller, and the maximum pressure drop is <20 Pa at flow rate 200 sccm.
4. One DC power supply is necessary. The required minimum output current is 50mA. The sensor actually consumes less than that in operation.
5. Calibrations at other gases available upon request.
