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 of a gas

Flow rate measurement

• Mass flowmeters

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

• Transmission rate between 1200bps and 115,200bps
• Readout functions: 03 (Read Holding Register) and 04 (Read Input Register)

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 panel case – FP-3021

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).
