摘要： Hand-held optical thromboelastographic sensor and method of using the same for simultaneous assessment of multiple parameters of blood coagulation at a point-of-care. The sensor includes an optical system registering laser speckle intensities associated with portions of a blood sample delivered through a fluid switch to analysis chambers of a cartridge of the sensor, and data-processing circuitry programmed to derive the multiple parameters from speckle intensity. The circuitry may be part of a mobile device configured to operate without communication with a central server and/or data storage.

摘要： Rheological measurement systems for use with systems including pressurized polymer melts and/or other viscous materials are described. In one embodiment, a rheometer is connected to an associated system with a bent, curved, or bendable tube to permit the rheometer to measure rheological properties in locations where the rheometer could not otherwise be located due to the presence of obstructions. Embodiments including rigid straight tubes for connecting a rheometer to an associated system are also described. In another embodiment, a flow-through rheometer is connected to an industry standard ½-20 thermowell aperture that is typically used for attaching temperature and pressure probes to a vessel containing a viscous material such as an extruder or injection molding system.

摘要： A drag reducing efficiency test is performed on a sample. The sample includes a crude-oil based fluid and a drag reducing agent. The sample is placed within an inner volume defined by a sample housing. A sensing portion of a sensor is submerged in the sample within the sample housing. The sensor includes a disk (sensing portion) and a supporting rod. A lid is placed on the sample housing to isolate the sample within the inner volume. The sensor is coupled to an air bearing motor. The sensor is rotated by the air bearing motor at a plurality of shear rates. For each shear rate, the sensor measures a torque applied by the sample on the disk in response to the disk rotating while submerged in the respective sample at the respective shear rate.

摘要： An apparatus and method are disclosed for accurately determining viscosity of Newtonian and non-Newtonian fluids in the field or in-service by using a potable field viscometer. The portable field viscometer includes a vertical disposable (or reusable) sample insert tube filled with the liquid which the viscosity is to be determined. Using fins on the needle surface, a needle having a known density is made to fall through the liquid in the disposable (or reusable) sample insert tube coaxially. Using the time that the needle takes to fall between two known distance marks on the extension bar attached the top of the needle or transducers such as light, laser or magnetic, the velocity of the needle falling through the liquid is determined. Thus, the viscosity can be calculated by using the velocity of a needle. In the method, viscosity, shear rate and shear stress can be determined according to the disclosed method.

摘要： A system includes a flow tube configured to receive a flow measured by an ultrasonic flow measurement, wherein a center region of the flow tube is configured to have a drop in pressure. The system also includes a heat source/hot wire and temperature sensors configured to enable a flow measured by a thermal massflow measurement. In the system, a controller is configured to compare the flow measured by the ultrasonic flow measurement to the flow measured by the thermal massflow measurement. The controller determines a ratio of the flow measured by an ultrasonic flow measurement to the flow measured on by the flow measurement based on thermal massflow. The controller also calculates a density, a thermal conductivity and an energy and/or gas content of the gas.

摘要： A viscosity measuring system is equipped with a tank, a flow pathway, an external force applying unit, and a pump. The viscosity measuring system further comprises a first pressure detection unit which detects a pressure of the electrode ink, and a second pressure detection unit which detects the pressure of the electrode ink on a more downstream side than the first pressure detection unit. A detection processing unit calculates a viscosity of the electrode ink based on the pressure detected by the first pressure detection unit and the pressure detected by the second pressure detection unit.

摘要： A method and a smart gas Internet of things (IoT) system for metering anti-interference of a gas ultrasonic meter. The IoT system including a smart gas user platform, a smart gas service platform, a smart gas sensing network platform, a smart gas object platform, and a smart gas device management platform. The method may be performed by the smart gas device management platform. The method may include: transmitting at least two sound waves of different frequencies at at least two time-dividing points and receiving at least two echo signals by the gas ultrasonic meter. The at least two time-dividing points may be determined at least based on time-dividing point correlation data; determining, based on the at least two echo signals, a gas flow difference; determining, based on the gas flow difference, whether a noise interference exists; and in response to a determination that the noise interference exists, adjusting a gas metering strategy.
