VA 520 – Inline flow meter

Applications-Technological Features

  • Digital interfaces such as Modbus-RTU, Ethernet (PoE) and M-Bus enable connection to higher-level systems such as energy management systems, building management systems, PLC,…
  • Easy and affordable installation
  • Units freely selectable via keys on the display m³/h, m³/min, l/min, l/s, kg/h, kg/min, kg/s, cfm
  • Compressed air counter up to 1,999,999,999 m³ can be reset to “zero” via keypad
  • Analog output 4…20 mA, pulse output (electrically isolated)
  • High measuring accuracy even in the lower measuring range (ideal for leakage measurement)
  • Negligibly small loss of pressure
  • Calorimetric measuring principle, no additional pressure and temperature measurement necessary, no mechanically moved parts
  • Comprehensive diagnostic functions can be read out on the display or remote access via Modbus-RTU such as exceeding max./ min values °C, calibration cycle, error codes, serial number. All parameters can be read out and changed via Modbus
