Process engineers who need to communicate flow measurement information over Modbus about air or gases flowing in line sizes from 0.25 to 24 inches (6 to 610 mm) will find the newly extended lines of ST51A and ST75A flow meters from Fluid Components International (FCI) provide the solution in a highly accurate, rugged, and compact instrument. 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, lead-free 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’re ideal for use with single function PLCs, pilot plant projects or large SCADA systems or complex plant DCS systems. In addition to Modbus, the ST51A and ST75A also prov...
