摘要： A launching tube for use with a liquid filled tank can be sized to accommodate a submersible vehicle for dispensing into the liquid tank. The tank can be an electrical transformer or any other liquid containing tank such as but not limited to a chemical tank. The launching tube can include a valve for insertion into a launching chamber, and a tank side valve for launching of the submersible into the tank. In one form the launching tube includes an antenna for communication with the submersible and/or a base station. The launching tube can also include a sensor such as a camera, as well as an agitator. The agitator can be used to facilitate bubble removal from the inside of the launching tube.

摘要： A testing device and method for floating rate of floating agent for fracture height control are provided. The test device includes a support frame, a glass tube vertically fixed on the support frame, a floating agent storage container, a control valve, and a liquid storage tank, wherein multiple circular holes are uniformly distributed along an axial direction of the glass tube, and multiple turbidimeters for measuring liquid turbidity are sequentially mounted on the circular holes. The liquid storage tank communicates with an inner cavity of an upper end of the glass tube through a pipeline, and the floating agent storage container is connected to an inner cavity of a lower end of the glass tube through a control valve. The present invention increases accuracy of measured floating rate of the floating agent, and provides reliable floating data of the floating agent for oil and gas reservoir reconstruction.

摘要： A density sensor to measure the density of a gas having a density ranging from 30 gram per cubic meter to 150 kilogram per cubic meter and a working pressure ranging from 0 to 100 bar. The density sensor includes a resonator housing, a membrane, an actuating/detecting module mechanically coupled to the membrane, and a resonating element arranged to be immersed in the gas, the resonating element being mechanically coupled to the membrane by a pedestal. The resonating element is a resonating disk having a thickness ranging from 25 μm to 200 μm and a diameter ranging from 4 mm to 12 mm. The resonating disk extends parallelly to the membrane or being angled relatively to the membrane and is coupled by its center to the pedestal. The resonating disk is made of a metal chosen among the group comprising stainless steel, nickel-iron alloy and Molybdenum.

摘要： A system for detecting a characteristic of a fluid. In one example, the system includes a tube, a float, a sensor, and a controller. The tube is configured to receive the fluid. The float is located within the tube. The sensor is configured to sense a position of the float. The controller is configured to receive, from the sensor, the position of the float, and determine a characteristic of the fluid based on the position of the float. The characteristic may be a density or a concentration.

摘要： Disclosed is an improved method for measuring the volume of an animal paw, suitable for use in a rat paw edema assay. Also disclosed is a novel apparatus for measuring the volume of liquid displaced by the insertion of an object into a liquid filled cup (1) which is on a cup holder basin (3), the liquid filled cup and cup holder basin being inside a rectangular support assembly (5), the measurement obtained by determining the buoyant force produced as a result of the displacement of the liquid by the animal paw.

摘要： A differential level hydrometer reduces the possibility for user error and provides an accurate, predictable, easy to use, reliable instrument for measuring the density (specific gravity) of a liquid. The differential level hydrometer works by automatically measuring the level of a liquid within a vessel and floating, in the liquid, a calibrated float having a precisely known volume and density. The instrument automatically measures the level of the liquid within the vessel while the float is floating in the liquid, and automatically calculates the density (specific gravity) of the liquid based on the two measured levels and the volume and density of the float. Temperature and meniscus correction may be used to improve repeatability and accuracy.

摘要： A sensing element and system for determining the density of fuel housed in the tank of an aircraft, includes sensing element (10). The sensing element has a disc shaped member (20) extending through a wall (16) of the sensor body. The sensor body also encloses a chamber (14) containing dry nitrogen at a pressure of one atmosphere. Electromagnetic driving coils (24) are electrically actuated to cause member 20 to vibrate in its resonant frequency in four quadrants with a node along an axis (22) corresponding to the wall of the sensor and a second node axis (42). Pickup coils (26) in the sensor body sense displacement of the disc shaped member in a location of maximum displacement. Fluid surrounding the sensing element causes mass loading of the exposed portion of the disc shaped member and changes its resonant frequency. The changes in resonant frequency along with values determined through calibration are used by a processor (44) to calculate the density of the fluid.
