VZO 4 y 8 OEM

  • fuel oil meters for OEMs (original equipment manufacturers), to be mounted under  the burner cover
  • meters with lateral internal threaded connections
  • with 230 V Reed pulser to display measurement values on remote totaliser or on burner control unit
  • for mounting in horizontal, vertical or inclined positions

Benefits and advantages of the VZO 4 and 8 OEM

  • Direct integration into burners: Designed for installation on the burner housing, facilitating integration into the equipment itself.
  • Accurate fuel consumption measurement: Enables fuel consumption monitoring with a repeatability of ±0.2% and a maximum error of approximately ±1% of the actual measured value.
  • Measurement data transmission: Using a Reed switch, measurement values can be displayed on a remote totaliser or the burner control unit.
  • Suitable for low flow rates: The VZO 4 and VZO 8 models support maximum flow rates of 80 and 200 l/h, respectively.
  • Flexible installation: Supports horizontal, vertical or inclined mounting to suit the equipment configuration.
