FIELD: instrument engineering.
SUBSTANCE: invention refers to measurement equipment and can be used at obtaining complex alkylene esters of (meth) acrylic acid by contact with alkanols. Technical result is provided by the fact that connecting pipe for measurement instruments used for analysis of flowing through pipelines fluid medium contains disk mounting ring. The ring consists of two flat end surfaces, outer side surface and side surface forming axial through hole. Note that mounting ring contains at least one radial hole that finishes at outer side surface to which measuring instrument can be connected. The diametre of axial through hole generally matches pipeline inner diametre.
EFFECT: provision of optimal control and regulation of measurement instrument operation.
