VA 520 - Flow meter for compressed air and gases

Recording and reducing energy costs and CO2 emissions while increasing the sustainability of any compressed air system. With our VA520 it is possible to monitor your consumption and analyze your leakage flows with just one measuring device. Due to its design, it is also ideal for mobile measurements.
 

Technical features

• Measurement of mass flow rate, output of standard volume flow rate 
• High accuracy for both small and large flows
• Pressure and temperature compensated by the thermal mass flow principle 
• Easy installation and removal of the sensor, the integrated measuring section can remain in the line for cleaning or recalibration of the sensor and can simply be closed with a sealing cap
• No moving parts, therefore low maintenance
• Vanishingly low pressure loss due to vanishingly low blockage of the diameter
• Can be used for compressed air and non-corrosive gases such as nitrogen, oxygen, argon, helium, etc.

• 04...20 mA, pulse and a Modbus RTU (RS 485) interface as standard, optional interfaces such as Modbus TCP (Ethernet), PoE, M-Bus 
• Optional interfaces such as Modbus TCP (Ethernet), PoE, M-Bus 
• Optional: Bi-directional measurement 
• Pressure range up to 40 bar
• Temperature range from -30 to 80°C
• Protection class IP65
• Integrated display to show the measured values 
• Can be used from DN 8 to DN 80
• Settings adjustable via the keys of the display 
• Main counter reading can be reset via the display 
• For velocities up to 224 Nm/s
• Highly accurate with an accuracy of ± 1.5% or ± 1% of the measured value  -  as well as ± 0.3% of the final value
