Mass flow rate and totalized flow, as well as other configuration variables, are displayed on the meter’s optional 2 x 12 LCD panel. 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. The Series 640S allows you to easily configure or change the following password protected parameters: flow range, totalizer, alarm settings, time response, low flow cut- 640S Series Steel-Mass™ off and a calibration correction factor that compensates for flow profile variations. Sierra’s Smart Interface™ software guides you through a procedure to fully validate instrument performance. The 5 Harris Court, Bldg.
