1) Even under pressure, the flow probe 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: 4.72, 6.30, 8.66, 11.81, 15.75 inches, (longer probes available on request). The flow probes are therefore suitable for being mounted into existing pipes with diameters of 1/2" to DN 300 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 to the respective probe length. (Probe length 8.66 inch = 220 mm maximum mounting depth). 2) If there is no suitable measuring site with 1/2" ball valve, there are two easy ways to set up a measuring site: A Weld on a 1/2" screw neck and screw on a 1/2" ball valve B Mount spot drilling collar incl. ball valve. By means of the drilling jig, it is possible to drill under pressure through the 1/2" ball valve into the existing pipe. The drilling chips are collected in a filter. Then install the probe as described under 1). 3) Due to the large measuring range of the probe even extreme requirements to the consumption measurement (high volume flow in small pipe diameters) can be met. The measuring range is depending on the pipe diameter. |
