The versatile microprocessor-based transmitter integrates the functions of flow measurement
The versatile microprocessor-based transmitter integrates the functions of flow measurement, flow-range 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 panel. The programmable transmitter is easily configured via an RS 232 communication port and interface software, or via the display and membrane 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, zero flow cut-off and a calibration correction factor that compensates for flow profile variations.
Features
Direct mass flow measurement eliminates the need for temperature and pressure corrections
Field adjustment of critical flow meter settings via on-board switches or terminal emulation program
Field validation of flow meter calibration
Direct mass flow monitoring eliminates need for temperature and pressure compensation
One-second response to changes in flow rate
FM standard, CSA and EEx certified for hazardous areas (optional)
