Process Viscometer KV100-F

larger version of the picture
The continuous-flow process viscometer KV100-F works on the principle of a Capillary Viscometer with continual volume flow and measurement of pressure decrease over the measuring capillary.

Its basic components are the driving head and the flow measuring device connected by a spacer tube. The driving head holds a synchronous motor with change gear. The immersion-type measuring unit holds a gear pump, the intake fitting and the exchangeable measuring capillary, as well as ducts for the supply of the process pressure and for the transport of overpressure from the entrance of the measuring capillary to the connections of pressure transducers.

The gear pump, which is driven by the driving head through a shaft via magnetic coupling at constant speed, continually takes a constant volume flow from the process medium and feeds it through the measuring capillary as a steady flow.

The pressure decrease between the two ends of the measuring capillary, which is proportional to viscosity, is determined by two pressure transducers P1 and P2. The signal transducer transforms the measuring signal into standard electrical signals 0...10 V. It can be used for display and as a control signal.

Screwed to the measuring device is a flow cell, which encloses the aspiration tube, measuring capillary and pump housing. So these parts are directly in the process medium positioned and temperature-controlled by this.

The flow measuring device is designed for use in the main or the secondary flow with low operating pressures. The inlet of the aspiration tube is always located within the representative substance flow.
