Production Description Gas Flow Meter Insertion In-Line FlowMeter CS VA500 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 Gas Flow Meter Insertion In-Line FlowMeter CS VA500 for compressed air
Easy installation and removal under pressure
1)Even under pressure, the flow sensor VA 500 is mounted by means of a stan- dard 1/2“ ball valve. During mounting and dismounting the circlip ring avoids an uncontrolled ejection of the probe which may be caused by the operating pressure.
For the mounting into different pipe diameters VA 500 is available in the following probe lengths: 120, 160, 220,
300, 400 mm.
So the flow sensors are being mounted into existing pipelines with inner diame- ters of 1/2“ upwards.
The exact positioning of the sensor in the middle of the pipe is granted by means of the engraved depth scale. The maxi- mum mounting depth corresponds with the resprective probe length. Example: VA 500 with probe length 220 mm has a maximum mounting depth of 220 mm.
2)If there is no suitable measuring point with 1/2 “ball valve, there are two easy ways to set up a measuring point:
A Weld on a 1/2“ screw neck and screw on a 1/2“ ball valve
B Mount spot drilling collar incl. ball valve (see accessories)
Drill holes can be drilled through the 1/2” ball valve into the existing tubing with the help of the drilling device, the drill chips are collected in a filter, then the probe is installed as described under 1).
3)Due to the large measuring range of the probe even extreme requirements to the flow measurement (high volume flow in small pipe diameters) can be met.
The measuring range is depending on the pipe diameter - see table on the right hand side.
