FCI ST51A and ST75A thermal dispersion flowmeters
FCI has announced that its ST51A and ST75A thermal dispersion flowmeters now have a Modbus option that 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 suitable 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 provide dual 4–20 mA, NAMUR NE43-compliant, analog outputs and a 500 Hz pulse output. Alternatively, instead of Modbus, the instruments can be provided with HART Version 7 I/O. The meters’ electronics are housed in a compact, rugged, IP67 rated, dual-conduit port (½″ NPT or M20 metric threading) transmitter enclosure, which is available in aluminium or a 316L stainless steel version. The transmitter can be mounted directly to the flow sensor or remotely mounted up to 30 m away.
The ST51A, ST75A and ST75AV flowmeters carry the CE mark, and are optionally available with Div.1/Zone 1 Ex agency approvals of FM, FMc, ATEX and IECEx. Additionally, they have also been independently verified to meet IEC 61508 for Safety Integrity Level (SIL-1) rating.
