CS mass flow meter VA-500 Gas and Air Flow Meter
Description
Contrary to the previously used bridge circuit the newly developed evaluation electronics records all measured values digitally.
This leads to a better accuracy also in case of large measuring
spans of 1:1000

Specification
Special features of flow sensor VA 500:
* RS 485 interface, Modbus-RTU as a standard
* Option integrated display for m³/h and m³
* Usable from 1/2" to 12" (DN 300)
* Easy installation under pressure
* 4...20 mA analogue output for m³/h resp. m³/min
* Pulse output for m³
* Inner diameter adjustable via keypad
* Consumption counter resettable
* Adjustable values at the display of the flow sensor: Reference conditions, °C and mbar, 4...20 mA scaling, pulse weight
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.
