QVis 01/o Process Viscometer

Our QVis 01/o inline viscosimeter automates your viscosity monitoring and generates measuring results that are reproducible and documentable.

Banish flow cups and  keep track of your fluid viscosity at all times!


Since measurement of the dynamic viscosity with QVis is completely independent of the direction of flow, the mounting of the QVis 01/o sensor can be realized in any form of pipe, regardless of the flow conditions in it. QVis can be operated in stand-alone mode or it can be connected to your PC: a comfortable Windows software is included in the delivery to allow you to automate measuring procedures and to further process the obtained data.



The QVis 01/o inline viscometer consists of only two components: a probe and a compact electronic unit which are connected with a flexible cable. The robust plastic housing includes an electronic control and evaluation system and can be mounted on the nearest wall or installed in your control cabinet.

The probe contains the unique SiO2 torsional tranducer and is equipped with a G 1″ screw connection to give you maximum flexibility in regard to the installation. Depending on your requirements further types of sensors (e.g. clamping-fastened sensors with a screw-cap or sensors with special thread or even flange connection) are available upon request.
