• 8 additional channels: measurement of additional quantities or calculations
• Additional quantities are omitted when performing calculations related to the flow measurement system
• Calculated quantities may serve as auxiliary values or be used directly in measurement systems
Recording measurement results
• Recording to internal 2GB memory
• Checksum secured files – protection against result errors
• Recording frequency for main archive between 3s and 24h; define two recording frequencies, toggled upon exceeding the set alarm thresholds
• Registration of counters, average, minimum and maximum values every 1 hour
Other functions
• Ability to measure, display and record additional values not related to settlement systems (eg condensate level in the tank)
• Algorithm of overshooting of the ordered power and of the excess energy meter with the possibility of registration saturation of superheated steam
• Advanced user and password system
• 1 optional 4-20mA analog output
• Available also in wall-mounted case – FP-3021N
Application
The FP-30×1(N) series flow computers are used in many industries: power plants, CHPs, metallurgical, food, chemical, wood and paper industries, etc. Example of application: calculating the amount of energy produced at the power plant; measurement of the flow and energy of steam used in the food industry for production purposes (pasteurization of processed products).
