The FS4308 series mass flow sensors are designed for general-purpose, precise gas metering, processing, monitoring, and/or control. The products are the third generation in the series, offering enhanced flow conditioning for greater installation flexibility, including manifold options. FS4308 also has a smaller footprint than its previous design. It has been applied to medical equipment, pneumatic control, process automation, and other industrial applications. The series offers a wide dynamic flow range, with a working pressure rating of up to 0.8 MPa (10 bar or 117 psi), and a compensated temperature range of -10 to +55°C. > Gas mass flow sensors > Patented flow conditioner FS4308 connector (AMPMODU MTE, 5 positions) and 0.5 m cable: Wire Color Definition 2 Green Analog output, i~5Vdc Note: 1. The three communication protocols share the ports as defined above. 2. The RS232 communication is bi-directional. TX is the transmit pin that sends data from the product. RX is the receive pin. The RS485 Modbus is asynchronous, half-duplex communication. . Siargo Ltd. 4677 Old Ironsides Drive, Suite 310, Santa Clara, CA 95054 +1 (408) 969.0368 [email protected] www.Siargo.com
