Record and reduce your energy costs and increase your sustainability with the VA 520. Monitor your consumption and analyze your leakages with a permanently installed flow meter in distribution stations, in front of individual departments or for billing purposes of individual consumers.

Special Features:

• Measurement of mass flow rate, output of standard volume flow rate
• Highly accurate at small as well as 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.

Technical details:

• 04...20 mA, pulse and a Modbus RTU (RS 485) interface as standard, 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 speeds 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
