PTZ 5.0

PTZ-BOX is a gas volume corrector that enables PTZ, PT or T conversion. The device is designed to measure volume, energy and flow of gas. Primarily battery powered with the possibility to connection to an external power supply. The device converts the volume of gas counted by the gas meter (turbine, rotary, diaphragm) into
the base conditions.

Main features of the PTZ-BOX:

  • Industrial housing communicates with various types of gas meter like turbine, rotary, diaphragm directly by LF, HF, NAMUR, ENCODER, Wiegand
  • 4 independent serial transmission ports (2 x RS-485 + optical interface 6205621+ NFC IEC 14443)
  • Built-in 4G/IoT modem (option)
  • Backlit graphic display
  • 5 configurable binary Ex inputs
  • 2 configurable binary NAMUR Ex inputs (working on battery mode)
  • Binary and frequency outputs
  • Eco power operation mode
  • Internal or external pressure transducers available
  • 10 years of archivable registered data storage (with monthly sampling interval)
