Process viscosimeter QVis 01/o

You want to analyze and control the viscosity of your fluids continuously during processing? The inline viscosimeter QVis 01/o  automates your viscosity monitoring and generates measuring results which are reproducible and documentable. Banish flow cups and  keep track of your fluid viscosity at all times!

Application

Since the determining of viscosity is independent of the direction of flow, the mounting of the QVis 01/o sensor can be realized in any pipe systems, regardless of flow conditions. The QVis can be operated in the stand-alone mode or it can be connected to a computer; for this a comfortable pc control program is included in the delivery. The program allows the user to automate measuring procedures and to further process the data obtained.

Composition

The inline viscosimeter QVis 01/o consits of a measuring head which is connected to the corresponding electronic unit with a flexible cable. The robust plastic casing of the electronic unit includes an electronic control and evaluation system and can be mounted directly on the wall or into a control cabinet.

The measuring head is equipped with a 1″-screw connection and allows maximum mounting flexibility. Depending on the customers´requirements, further types (e.g. sensor with special thread or flange connection) are avaiable upon request. For the measuring head, different sensors for different applications are offered: A distinction is made between sensors for electrically conducting and non-conducting fluids as well as for sensors suited for high temperature or high pressure applications. We have the right sensor for your application and will gladly assist you.
