| Additional Information |
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: A Weld on a 1/2" screw neck and screw on a 1/2" ball valve 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. |
