Releases FlowTune™

Release date: 25-10-2022


Date: 25-10-2022
Main changes:
  • Added support for EL-FLOW Prestige hardware revision (SW3 sensor).


Date: 16-04-2021
Main changes:
  • Reworked how available fluid list is determined. System requirement “For FlowTune [customer version] no newer version of another FlowTune may be installed on the same PC to avoid the fluid list being reduced to the BHT fluid list” is therefore no longer a limitation and has been removed from system requirements.


Date: 14-09-2020
Main changes:
  • Fluidsets can be edited for instruments containing a C5 control valve.
  • F-004 (AC/AI/BI) control valve is supported for EL-FLOW Prestige product series.


Date: 21-12-2018
Main changes:
  • Limit allowed minimum pressure to 150 psi for EL-FLOW Prestige PI with 10 bar sensor.
  • “The densities are needed” error no longer occurs on adding a fluidset for EL-FLOW Select instruments.
  • Removed NO2 from EL-FLOW Prestige gas list.


Date: 12-12-2018
Main changes:
  • Added support for EL-FLOW Prestige with 100 on-board gases.
  • Corrected allowed minimum temperature and pressure for EL-FLOW Prestige product series.


Date: 18-01-2018

Main changes:
  • Added support for F-033C and F-033CI valves.


Date: 27-10-2017
Main changes:
  • Added support for F-021AV valve.
  • When no COM port is available, a friendly error message is shown.


Date: 21-09-2016 
Main changes:
  • Fixed error message on opening Edit fluidset window for certain fluids for EL-FLOW Prestige instruments.
  • Pressure outlet can be 0 bar (a).


Date: 15-04-2016 
Main changes:
  • When a new fluidset is added, FlowTune shows the fluid of fluidset 1 by default. However, when the fluid of fluidset 1 is not in the FlowTune fluid list, the new fluidset starts with fluid Air. In that case, it is written to an EL-FLOW Prestige instrument immediately, so the flow range, calculated by the instrument, is calculated correctly.
  • The parity can be changed for Modbus.


Date: 05-02-2016 
Main changes:
  • Updated allowed pressures to match 1500/1000/150 psi (g) equivalent.
  • When fluidset 1 is an actual fluid calibrated fluidset, the pressure of an added fluidset can be set up to the maximum allowed pressure without opening and closing the Edit fluidset window first.
