FP-3031 flow computer can handle up to two independent main applications A, B or C. 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 ac

In the device there are five measuring inputs enabling connection of sensors and transmitters of various type: 3 x RTD/I - three inputs designed for direct connection of resistive temperature sensors (Pt-100, Pt-200, Pt-500, Pt-1000 or Ni-100, Ni-200,Ni-1000) or 0/4-20 mA current loop transmitters, 4 x I – four inputs enable connection of 0/4-20 mA current loop transmitter, 3 x I/PULS - three inputs enable flow rate measurement from a pulse transmitter (0,001 Hz to 10 kHz) or 0/4-20mA current loop transmitter.
