• Software for visualization of measurement results 
• Wall-mounted case
19-buttons extended keyboard version (makes it easier to enter and edit numbers, text, formulas and passwords)
• Powered with 230V or 24 V 


Available in two versions

• Basic - implementation of one settlement system
• Extended - implementation of up to three settlement systems A, B, C 

Applications for steam, liquids and technical gases

Process values and calculations relevant to a single installation application are grouped in one system named main application. FP-3031 flow computer can handle up to three independent main applications A, B or C. Configuration wizard helps to setup one of possible applications
• The flow and heat of a liquid medium
• The flow and delta heat of a liquid medium in a closed supply-return installation
• The flow and delta heat of a liquid medium in an installation with different supply and return flow rates
• The flow and heat of a steam
• The flow and delta heat in a closed steam-condensate installation
• The flow and delta heat in a steam-condensate installation with different steam and condensate flow rates
• The flow and delta heat in a steam-generating installation with the supplied water flow rate measured
• The flow of a gas 

Flow rate measurement

• Mass flowmeters
• Volume flowmeters
• Differential pressure devices (orifices and nozzles) according to iteration algorithm according to PN-EN ISO 5167 standard (only for water and steam)


The device has ten measurement inputs
• 3 x RTD/I, three inputs adapted for connection of resistance temperature sensors (Pt100, Pt200, Pt500, Pt1000, Ni100, Ni1000) and transducers with a 0/4‑20mA current output
• 4 x I, four inputs for interaction with 0/4‑20mA transducers only
 3 x I/PULSthree inputs intended for connection of transducers with a 0/4‑20mA current output or with a pulse output (range 0.001Hz … 10kHz) 

Measurement and additional calculations

• 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 3 s and 24 h; 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 or 2 optional 4-20mA analog outputs
• Available also in panel case – FP-3031 


The FP-30x1(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).
