Abstract
The present invention relates to in-line viscometers with no moving parts for monitoring the viscosity of fluids. One embodiment of the invention is a viscometer including a first tube, a second tube, a first flow metering device coupled with the first tube, a second flow metering device coupled with the second tube. The second tube is larger in diameter than the first tube. Another embodiment is directed to a method for maintaining a desired viscosity during a process.
Claims15
A viscometer comprising:
- a first tube having a first cross-sectional area;
- a second tube having a second-cross sectional area, wherein the second cross-sectional area of the second tube is larger than the first cross-sectional area of the first tube;
- a restrictor disposed in the second tube;
- a first chamber formed between an inlet of the viscometer and an inlet of the first and second tubes respectively, the first chamber having a wider diameter than the inlet of the viscometer;
- a second chamber formed between an outlet of the viscometer and an outlet of the first and second tube respectively, the second chamber having a wider diameter than the outlet of the viscometer;
- a first ultrasound flow metering device coupled with the first tube, the first ultrasound flow metering device measuring a first velocity of fluid flowing through the first tube;
- and
- a second ultrasound flow metering device coupled with the second tube, the second ultrasound flow metering device measuring a second velocity of fluid flowing through the second tube.
