3. Installation
3.1 Overview
MGP260 can be installed either directly into the process (for example, through a flange or ball
valve in the actual process pipeline), or using a flow-through adapter (for example, in a
sampling line installation or when performing a field calibration).
For an overview of installing MGP260 directly in the process, see Installation option: ball valve
installation (page 21) .
For an overview of the flow-through adapter installation option, see Installation option: flow-
through adapter installation (page 22) .

MGP260 comes shipped with an NPT 1.5" male thread test plug (Vaisala order code:
257525SP). If you are uncertain about the thread type of the process connector you want to
install MGP260 into, use the thread test plug to check that it fits into the process connector
threads (that is, that the process connector thread type is NPT 1.5" female ).
