Flow Controller
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
MRC 7800
