Reduce your energy costs and increase your efficiency with the VD 500. Suitable directly for measurement after the compressor. Monitor the delivery rate of your compressor and create a FAD analysis.

Field of application:

• Measuring directly after the compressor
• Measuring at high temperatures
• Measuring fast processes

Advantages of the differential pressure sensor VD 500:

• Proven measuring principle by measuring the differential pressure (dynamic pressure)
• Pressure and temperature compensated, thus output of the standard volume flow rate
• Particularly suitable for extremely high flow rates
• Extremely fast response time of 100 ms
• Quick and easy installation via a ½” ball valve
• No moving parts, therefore low maintenance effort
• Negligible low pressure loss due to negligible low blockage of the diameter
• Applicable for wet and hot compressed air directly after the compressor

Typical applications:

• Measurement of the delivery quantity of compressors
• Compressed air audits
• Efficiency measurement of compressed air systems

Installation conditions:

• After working water separator
• In horizontal lines (recommended) or in risers

Technical details:

• 04…20 mA, pulse and a Modbus RTU (RS 485) interface as standard
• Optional interfaces like Modbus TCP (Ethernet), PoE, M-Bus
• Pressure range up to 20 bar
• Temperature range up to 180°C
• Integrated display to show the measured values
• Available from DN20 to DN500
• Easy installation under pressure
• Settings adjustable via the keys of the display
• Main counter reading can be reset via the display
• Can be used for velocities up to 600 Nm/s
• High accuracy with 1.5% deviation of the measured value
