Reduce your energy costs & increase efficiency with the VD500<\/h2>\n

The VD 500 is an innovative flow monitor<\/strong> that measures the delivery rate of your compressor<\/strong> in real time and creates a Flow Analysis Diagram (FAD). This diagram provides invaluable information about your compressor\u2019s performance so you can make informed decisions about efficiency and cost savings.<\/strong><\/p>\n

To automate and control<\/strong> this process, the VD 500 integrates directly with the\u00a0ezeio hardware<\/a> via modbus for accurate reporting and control capabilities. Learn more about this in the “automate + control” tab above.<\/p>\n

Field of application:<\/h3>\n
    \n
  • Measuring directly after the compressor<\/li>\n
  • Measuring at high temperatures<\/li>\n
  • Measuring fast processes<\/li>\n<\/ul>\n

    Advantages of the differential pressure sensor VD 500:<\/h3>\n
      \n
    • Proven measuring principle by measuring the differential pressure (dynamic pressure)<\/li>\n
    • Pressure and temperature compensated, thus output of the standard volume flow rate<\/li>\n
    • Particularly suitable for extremely high flow rates<\/li>\n
    • Extremely fast response time of 100 ms<\/li>\n
    • Quick and easy installation via a \u00bd” ball valve<\/li>\n
    • No moving parts, therefore low maintenance effort<\/li>\n
    • Negligible low pressure loss due to negligible low blockage of the diameter<\/li>\n
    • Applicable for wet and hot compressed air directly after the compressor<\/li>\n<\/ul>\n

      Typical Applications:<\/h3>\n
        \n
      • Measurement of the delivery quantity of compressors<\/li>\n
      • Compressed air audits<\/li>\n
      • Efficiency measurement of compressed air systems<\/li>\n<\/ul>\n

        Installation conditions:<\/h3>\n
          \n
        • After working water separator<\/li>\n
        • In horizontal lines (recommended) or in risers<\/li>\n<\/ul>\n

          Technical details:<\/h3>\n
            \n
          • 04…20 mA, pulse and a Modbus RTU (RS 485) interface as standard<\/li>\n
          • Optional interfaces like Modbus TCP (Ethernet), PoE, M-Bus<\/li>\n
          • Pressure range up to 20 bar<\/li>\n
          • Temperature range up to 180\u00b0C<\/li>\n
          • Integrated display to show the measured values<\/li>\n
          • Available from DN20 to DN500<\/li>\n
          • Easy installation under pressure<\/li>\n
          • Settings adjustable via the keys of the display<\/li>\n
          • Main counter reading can be reset via the display<\/li>\n
          • Can be used for velocities up to 600 Nm\/s<\/li>\n
          • High accuracy with 1.5% deviation of the measured value<\/li>\n<\/ul>\n<\/div>\n<\/div>\n<\/div>\n<\/div>","protected":false},"excerpt":{"rendered":"
