By connecting the instrument to the RS232/RS485 port of a PC or lap-top and running free ZFM Configuration Utility software, the user can select different gas types and flow ranges within a few minutes without removing the instrument from the installation.

Features:

  • Automatic sensor zero offset adjustment (digital interface or local push button)
  • Digital interface (RS-232 or RS-485) test/configuration port (optional Modbus RTU with isolated RS-485 transceiver)
  • Two programmable Totalizers
  • Full scale covered flow ranges from 3.5 sml/min to 10 sl/min in seven models
  • Selectable analog 0-5 Vdc, 0-10 Vdc, or 4-20mA outputs
  • Universal 14-24 Vdc power supply input
