    The continuous-flow process viscometer KV100-Ex 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 investigated by a differential pressure transducer. Pressure  
    differences are transformed into standard electrical signals 4...20 mA, which 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.  
       
    The process viscometer can be completed with an electronics unit for more functions of  
    instrument control, signal processing, correction of characteristic lines of the gear pump,  
    as well as for the temperature adjustment of viscosity.
