General Description

The Welker Automatic insertion Devices have been designed to safely insert probes, ultrasonic heads, thermowells, hydrometers, siphons, injection nobles, temperature sensors, microphones and corrosion coupons into pipelines of all pressures and sizes. This unique design eliminates the worry and necessity to vent a gas or liquid into the atmosphere in order to blowdown a section of pipeline where you need to work. The only power that is needed is the pressure in your pipeline, completely self contained.
