AQUAMETRO VZF(A) II SERIES

A versatile flow meter for oil, heavy oil and many other oil-like liquids. It is used for efficient consumption measurement of heat burners and various combustion engines. A reliable solution for any application where oil is consumed.

Tính năng:

  • State-of-the-art design
  • Electronic counter, mass flow, volume flow indication, multiple output signals
  • Integrated temperature sensor
  • No straight inlets or outlets required
  • Independent of viscosity and temperature
  • High vibration resistance
  • Optional: metrological type approval
  • Automatic medium switch based on temperature
