The new Modbus option for the ST51A and ST75A flow meters represents FCI’s continued commitment to providing optimal thermal mass flow meter design and value. They combine highly dependable surface-mount, leadfree RoHS compliant electronics with highly accurate, repeatable all-welded, equal-mass flow sensors. Their no-moving parts design is virtually maintenance free and offers an exceptionally long life.FCI’s ST51A and ST75A flow meters’ Modbus option meets the EIA/TIA-485 standard and provides mass flow rate, totalised flow, and temperature data. Transmission mode is via RTU, or ASCII with standard MS (16 bit), standard LS (16 bit), or Daniel extensions (32 bit). They are ideal for use with single function PLCs, pilot plant projects, or large SCADA systems, or complex plant DCS systems.
