Ultrasonic Gas Meter GUVR-011 A2.2/IS/314 with autonomous power supply

guvr-011-a2-2

TECHNICAL FEATURES

  • Meters provide gas measurement in pipes with nominal diameter (DN) of 50 to 300 mm.
  • Measurement range of gas flow rates varies from 0.15 to 35.0 m/s.
  • The flow rate of gas which has passed through the pipeline in the reverse direction has a negative value.
  • Communication with the meter is performed via RS-232/RS-485 interface.
  • Information sharing protocol – ModBus RTU.
  • RS-232 communication link only works when there is an external supply voltage of 8 to 9 V.
  • Meter is powered by built-in lithium battery with capacity of 19 Ah, service life of 2 years.
  • Meters are made (on the order conditions) at a maximum operating pressure of 1.6; 6.3; 10 and 16 MPa.
