Easy mounting/dismounting of VA 550 under pressure - without disconnection of the line without emptying the line If there is no suitable measuring site with 1/2" ball valve, there are two simple possibilities to set up a measuring site: Engraved depth scale for precise installation 180 Installation depth = x + y dA = outer diameter x = dA 2 B Mount spot drilling collar including 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 the probe can be mounted. A Weld...
