FP-3021N FP-3021 Flow and Energy Computer for Steam, Liquids and Gases with advanced data recording for HART or RS485 / MODBUS RTU sensors            Handles up to 2 independent installations 5 channels for HART / Modbus RTU sensors 2 digital channels Alarm & control functions, 4 output relays Analog 4-20mA output (option) Advanced data recording for process values and totalisers User configurable data presentation on color TFT display RS485 communication port, ASCII and Modbus RTU protocols Ethernet port, Modbus TCP and server WWW GSM module (option) Software for configuration and recorded data presentation APPLICATION:  Measurement of steam and water in various industrial installations  Measurements of industrial gases and typical or special liquids (like glycol, supercooled water, oils) in heat exchange systems with possibility of local alarming or simple control implementation  Application in distributed control systems with local measurement and data display  Systems with precise data logging for audit trials 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 and B. A 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. APPLICATION SCOPE FOR STEAM MEASUREMENTS The flow computer performs flow and heat measurement of superheated or saturated steam or water according to IAPWS-IF97 recommendations in the operating range of temperature 0…800 ºC and absolute pressure 0,05…16,52 MPa. Flow and energy measurements of liquids other than water are performed in the range of tabular values entered by user – density and enthalpy as function of temperature. FLOW RATE MEASUREMENT     The flow computer can use: mass flowmeters, volume flowmeters, differential pressure devices with approximation by square root curve, differential pressure devices (orifices and nozzles) according to iteration algorithm accord
