AFM0710H00 Thermal MEMS Gas Mass Flow Meter RS485 Modbus RTU

AFM0710H00 Thermal MEMS Gas Mass Flow Meter RS485 Modbus RTU

Typical Applications

Used for flow monitoring in laser systems, gas-shielded welding, laboratories, oxygen generators, compressed air applications, environmental monitoring, and the pharmaceutical and food industries; frequently used as a replacement for the SMC PFM7 series of flow switches.

Specification:

Output Signals (all three available simultaneously)

1. RS485 Modbus RTU (mainstream, recommended); default: 9600 baud, address: 0x01
2. 1–5V analog voltage: 1V = 0 flow rate, 5V = full-scale flow (10 L/min)
3. Two NPN open-collector alarm outputs: NPN1 for high-limit alarm, NPN2 for low-limit alarm; can be connected to external indicator lights or relays.
