Product Details
Digital display CS Flow Meter VA500 / VA520 inline flowmeter for compressed air and gases
Description
Measurement of mass flow direct output of standard volume flow
Highly accurate at small as well as higher flow rates
Pressure and temperature compensated by the thermal mass flow
principle
Quick and easy installation via a ½" ball valve
No moving parts, thus low maintenance
Vanishingly low pressure drop 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.

Application-technological features of the flow meters VA 520
• 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 aff ordable 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
