Covimat 105 DC

Covimat 105 DC 
… is a process viscometer for measuring liquids in pipes.

Each process viscometer DC is made up of three parts:

  • the measuring head
  • the measuring cell with distance piece
  • the measuring bob

The measurement..
… of the sample is done in the ring pipe as shown in the illustration. Installation and connection are easy to realize and require few efforts.


The measuring head…

…includes the electronicswhich have two main functions:

It keeps rotating the measuring bob at the desired rotational speed and it records the torque by a torsion element. The torque is turned into a 4 – 20 mA signal.

The electronics are explosion proof according ATEX.

Depending on the application the measuring head can be equiped with different torsion elements and/or a gear unit. 


  • The measuring system…

    …is made up of a flow-through cell. The measuring cup with the distance piece is fixed in the cell. The distance piece allows viscosity measurements at high temperatures up to 300°C.  

    A specific feature of these measuring cells is the absence of a bushing. The power transmission is done by a magnetic coupling. therefor the cells are completely encased and allow viscosity measurement at high pressure.  

    The measuring cells can be delivered with or without temperature jacket. The installation of the cell is possible according to your needs by (attachment) screw, flange or welding.

    The measuring bob…

    …determines the measuring range. The larger the bob the more low-viscous can be measured. Usually the measuring system is made of high-grade steel, but can be delivered coated or in different materials as well.
