• Extended - implementation of up to three settlement systems A, B 

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-3021 flow computer can handle up to two independent main applications A or B. 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) 

Measurement channels

• 5 channels intended for data readout from Modbus RTU protocol devices and transducers and HART protocol transducers
• Two channels intended for interaction with PULS-type inputs (measurement of frequencies within the range of 0.001Hz … 10kHz, pulse counting, tracking and recording the shorting / disconnecting binary signal) 

HART

• Readout of digital quantities from transducers / devices connected in parallel to a current loop
• Operation as Primary Master or Secondary Master
• Readout of variables: PV – primary variable, SV – secondary variable, TV – third variable, FV – fourth variable 

MODBUS RTU

• Devices / transducers connected in parallel to one pair of wires (of an RS-485(1) port)
• Transmission rate between 1200bps and 115,200bps
• Readout functions: 03 (Read Holding Register) and 04 (Read Input Register)
• Supported formats of variables: Uns. Integer, Integer, Uns. Long, Uns. Long(sw), Long, Long(sw), Float, Float(sw) 

Measurements and additional calculations

Math functions to perform calculations on measured quantities (eg Sum of flows and power in two pipelines, etc.)
• 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-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).
