Description

The MRC 7800 Flow Controller is a microprocessor based circular chart recorder capable of measuring, displaying, recording and totaling flow process variables. Record functions, alarm settings and other parameters are easily configured from the front mounted keypad and self-prompting displays.

All user data can be protected from unauthorized changes by the Enable Mode security system. The MRC7800 is protected against loss of data from AC power failures by a standard battery backup system.

Applications for the MRC 7800 include process validation, trend analysis, regulatory compliance and product safety. Flow tracking is available with the optional totalizing capability.

Standard features:
  • 8 Digit display per pen
  • Isolated linear sensor input: mA, mV, V
  • Square-root extraction
  • Variable exponent for weirs and flumes
  • Custom curves for flow correction, linearization, of height to volume conversion
  • Pressure compensated DP flow calculation
  • Adjustable flow time base - per sec, per min, per hour, and per day
  • Chart speed from 0.1 to 999.9 hours
  • Disposable fiber tipped pens: red, green
