Page 11: Rs232 Communication Protocol
None Flow control: None The FS4001 has three options in communication: A. Data transmission mode: This allows the user to read the data continuously from the product: 1) Send 0x9d to the sensor and receive 0x9d from the sensor; 2) Send 0x56 to the sensor and receive 0x56 from the sensor;... - Page 12 The sensor will return a single instant flow rate value via RS232. The data format is: ffffffff IN USER MODE..\n\r where the value represents an instant flow rate of fffff.fff sccm. And the "IN USER MODE..\n\r" means the sensor stops data transmission. www.Siargo.com FS4001 User Manual...
