Metronic FP-3021

Flow computer for calculating compensated flow and thermal energy of steam, water and other liquid media and compensated flow of process gases with electronically registered results. The computer communicates with RS‑485 / Modbus RTU and HART transducers.

• Simultaneous consumption calculations in up to two different measurement systems (A, B) for separate process lines.
• The computer enables:
  • compensated flow and energy measurement of unsaturated or saturated vapour and water according to IAPWS-IF97 guidelines,
  • compensated flow and energy measurement of other liquids, calculations are made within a range of tabular values entered by the user,
  • compensated flow measurement of process gases.
• The computers can interact with the following types of flowmeters:
  • mass flowmeter,
  • volumetric flowmeter,
  • differential pressure flowmeter with approximation using root characteristic or according to an iterative algorithm, compliant with PN-EN ISO 5167 (only for water and steam).
• Measurement channels:
  • 5 channels intended for data readout from Modbus RTU protocol devices and transducers and HART protocol transducers.
  • 2 channels intended for interaction with PULS-type inputs.
• 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).
• 2 PULS-type inputs:
  • measurement of frequencies within the range of 0.001Hz … 10kHz,
  • pulse counting,
  • tracking and recording the shorting / disconnecting binary signal.
•  4 semiconducting output relays: alarm and control functions.
• Optional 4-20mA analog output.
• Ports:
  • RS485 port: ASCII or MODBUS RTU protocol ,
  • Ethernet port: Modbus TCP protocol, Web server.
• Advanced recording function allows storage of measurement results in the internal 2GB data memory:
  • USB port for transferring data to and from the computer,
  • data are saved in a text file, secured with an encrypted checksum and stored in the 2GB internal memory.
• 8 additional channels: measurement of additional quantities or calculations.
• Colour graphic LCD TFT display.

Application

• Measuring and calculating the consumption of steam and water in balancing systems.
• Measuring the compensated flow of process gases and other liquid media (glycol, chilled water).
• Measuring dispersed points with the option to operate in computer systems.
• Measuring with recording of results and local readout of results, or periodic readout of recorded data using a USB mass storage device.
