Product Description

CS Flow Meter VA500 with display VA520 Gas and Air Flow Meter for continuous flow measurements.

Description 

Thermal mass flow sensor for compressed air and gases
Recording and reducing energy costs and CO2 emissions while increasing the sustainability of any compressed air system. With our VA500 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.

Features 

1) even under pressure , the flow sensor VA 500 is mounted by means of a standard 1/2" ball valve. During mounting and dismounting the safety 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 sensor are being mounting intoexisting pipelines with inner diameters 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 maximum 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 site with a 1/2" ball valve present there are two simple possibilities 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)

By means of the drilling jig it is possible to drill under pressure through the 1/2" ball valve into the existing pipeline. The drilling 
chips are collected in a filter. the the probe can be mounted as described under point A

3) Due to the large measuring range of the probe even extreme requirements to the consumption measurement (high volume flow in small pipe diameter) can be met.
The measuring range is depending on the pipe diameter - see table on the right hand side.
