Production Description CS Instruments Mass Flow Meter VA520
flowmeter for compressed air
With the development of modern industry, energy saving and
environmental protection have become more and more crucial, and are
also very concerned by most advanced enterprises. As a new type of
power source, compressed air should be applied to every corner of
the enterprise in an all-round way. At the same time, how to ensure
the efficient operation of compressed air, flow detection and
control become very important. As we all know, the compressor
converts 85% of electricity into heat, and only 15% into compressed
air, so compressed air is much more expensive than electricity.
Effective monitoring and management of compressed air is a lot
smarter.

Features CS Instruments Mass Flow Meter VA520 flowmeter for compressed air
Easy installation in existing piping through integrated measuring
sec-
tion (1/4” to 2“)
High measuring accuracy due to defined measuring section (inlet and
outlet section)
•Digital interfaces such as Modbus RTU, Ethernet (PoE) and M-Bus
enable connection to higher-level systems such as energy ma-
nagement systems, building management systems, SPS,...
•Easy and auordable installation
•Units freely selectable via keys at 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. Resetable to „zero“
via keypad
•Analogue output 4...20 mA, pulse output (galvanically separated)
•High measuring accuracy also 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 diagnosis functions can be read out at the display
or by remote access via Modbus-RTU like e. g. exceeding Max./ Min
values °C, calibration cycle, error codes, serial number. All
parameters can be read out and changed via Modbus
