ZG4 (S) METLAB PRE-PAID GAS METER

Home type smart prepaid gas meer produced according to 2004/22/EC direktives and EN 1359 & OIML standards.

MAIN FUNCTIONS

  • Ideal result in measurement of home and commercial types of natural gas.
  • Smart meter working by software, CPU based circuit, smart card and LCD screen.
  • Magnetic reading and crediting of mechanical meter by electronic circuit.
  • Embedded auto opening/closing gas valve by electronic control.
  • Continuous controlling of meter for loaded credit, working conditions, illegal usage, and auto closing the meter in case of need.
  • High data security by preventing copying smart cards.
  • All connections of prepaid system with mechanical meter and valve cannot be reached without opening the cover.
  • Security cut-off gas in case of problem.
  • Continuous detecting the credit status and working conditions of meter resulting to auto closing valve in case of need.
  • Remote reading by hand terminal (optional)
  • Polyester powder coated inside -outside surface ensuring corrosion free and smooth meter.
  • Nitric synthetic plastic containing polyester coated diaphragm.
  • Special screws and nuts preventing illegal opening of meter.
  • Prevention of reverse gas entry by test resistor system.
  • Flexible and stable system by 360˚ rotating valve ensuring stain free and frost free system.

ADVANTAGES OF REMOTE CONTROL SYSTEM (Optional)

Remote reading, remote on/off and controlling the parameters by a hand terminal or mobile phone.
