On-line viscometer.This viscometer viscometer Instrument for measuring the viscosity (resistance to internal flow) of a fluid. In one type, the time taken for a given volume of fluid to flow through an opening is recorded. for on-line measurement of melt viscosity features a compact design for monitoring and recording rheological parameters. The on-line viscosity measurement device, or viscosimeter viscosimeter an apparatus used in measuring viscosity of a substance. , is fitted between two flange flange (flanj) a projecting border or edge; in dentistry, that part of the denture base which extends from around the embedded teeth to the border of the denture. flange n. 1. connections. The melt channel can be designed according to according to prep. 1. As stated or indicated by; on the authority of: according to historians. 2. In keeping with: according to instructions. 3. specifications between 0.8 and 4 inches. The unit includes a pump drive, a pump, pressure transducers, temperature sensors and the control and evaluation electronics. The setting of process parameters, the evaluation and the display are realized via a user-friendly touchscreen panel, or alternatively can be integrated into an existing control system. By means of a high precision metering gear pump A Gear pump uses the meshing of gears to pump fluid by displacement. They are one of the most common types of pumps for hydraulic fluid power applications. Gear pumps however are also widely used in chemical installations to pump fluid with a certain viscosity. , a small amount of polymer melt is diverted from the main melt channel and pumped through a precisely manufactured slot capillary. Melt temperature and melt pressure (at two locations) are measured. Based on internal calculations, the viscosimeter monitors the value of the representative shear rate and the corresponding viscosity. Different shear rates can be set, and by corresponding corrections the real values for viscosity and shear rate can be derived. (Gneuss) Circle 105 on card |
