Digital thermal mass flow-meter Teledyne Hastings Instruments

The latest product line developed by Teledyne Hastings Instruments is the digital version of the high capacity flow instruments. These new digital instruments allow measurement and/or control up to 10,000 slm. The new line complements the existing lower flow Digital Metaline(R) (5 sccm to 30 slm).

The two product lines, Digital Metaline and the new high capacity digital flow instruments, offer flow meters and controllers from 5 sccm to 10,000 slm, with superior accuracy. The lower flow Digital Metaline units have all-metal seals. A 4µ-inch Ra finish is available for flow rates up to 10 slm. Multiple gas calibrations and stored gas conversion factors are key features that set these instruments apart from the analog versions.

Both the Digital Metaline and the high-capacity digital flow instruments feature flexible operation with ±12, ±15 or 24 VDC power supply and transparent operation in analog or digital modes. All digital units are available with RS232 or RS485 interface with baud rates up to 19.2 kbaud. In addition, the instruments offer convenient self-diagnostics including warnings and alarms for flow, sensor, and valve status.
