OVERVIEW

The FlatTrak™ 780S flow body eliminates velocity profile distortions, swirl and temperature stratifications in the gas stream and reduces the amount of upstream piping required for accurate flow measurement.

The versatile microprocessor-based transmitter integrates the functions of flow measurement, flowrange adjustment, meter validation and diagnostics, in either a probe-mounted or remote housing. Mass flow rate and totalized flow, as well as other configuration variables, are displayed on the meter’s optional 2 x 12 LCD display. The programmable transmitter is easily configured via an RS-232 communication port and Sierra’s Smart Interface™ software, or via the display and magnetic switches on the instrument panel.

Sierra’s state-of-the-art calibration facility insures that the calibration will match the application, and our patented Dry-Sense™ thermal sensor insures the 640S will hold this calibration over time.

Sierra’s Smart Interface™ software guides you through a procedure to fully validate instrument performance. The meter is available with a variety of input power, output signals, mounting and packaging options.
