With the development of science and the widespread use of automated control systems, people are increasingly dissatisfied with obtaining viscosity parameters from the laboratory to control product quality. Existing methods include capillary viscometry, rotational viscometry, falling ball viscometry, and many others. New viscosity measurement technologies have also emerged to cater to specific fluids and measurement requirements. One such technology is the vibrating online viscometer, which is a specialized instrument for real-time viscosity measurement in process environments. It utilizes a conical cylindrical element that oscillates rotationally along its radial direction at a certain frequency. The sensor is a conical spherical element through which the fluid flows on its surface. When the probe shears the fluid, it experiences energy loss due to viscosity resistance, and this energy loss is detected by electronic circuits and converted into a displayable viscosity reading by a processor. This instrument can measure the viscosity of different media by changing the shape of the sensor element, thereby having a wide range of viscosity measurement capabilities. As the fluid shearing is achieved through vibration, there are no relative moving parts, seals, or bearings, making it a fully sealed and pressure-resistant structure. It can be widely used for precise viscosity measurement in industrial and laboratory settings. To meet personalized requirements of users, our company has developed different installation structures and insertion depths for online viscometers, not limited to side openings or top openings for retrofitting in chemical pipelines, containers, and reaction vessels. In order to address the issue of distance from the liquid surface, our online viscometers can be directly inserted from the top, typically achieving insertion depths from 500mm to 4000mm with an insertion diameter of 80mm, and can be equipped with DN100 flanges for viscosity measurement and control in reaction vessels.
