Electronic gas flow recorder MacREJ 5 R
MacREJ 5 R is a device registering gas volume from two independent gas meters using low frequency LF signals.
The recorder can be equipped with up to four contact inputs – monitoring operation of pressure reducers.
The device can work in zone “0” of explosion hazard.
Remote or wired data transmission
The device was developed in response to the need for wired data transmission.
Data transmission from the recorder is possible using twoindependent transmission ports RS485 with the use of GAZMODEM or Modbus RTU protocols.
The recorder has a display that allows comfortable work in negative temperatures.
- Easy installation and configurability via a phone with NFC interface.
- Analysis of the recorded measurement data thanks to widgets showing trends in the form of bargraphs.
- Data transmission via cable or remote connection thanks to built-in Cat.1 modem
- Backlit graphic display, 4″ dedicated to work in temperatures down to -30 °Celsius
- Operation on battery power supply up to 15 years. Possibility of connecting mains power supply.
- Four independent serial transmission ports.
- 6 intrinsically safe configurable binary inputs
- 2 configurable NAMUR inputs even with battery power supply.
- Binary and frequency outputs in intrinsically safe execution
- Volume registration from two independent gas meters. Two independent transmission ports.
