Temperature field measurement and balancing method and device for electronic thermometer calibration

The present invention discloses a temperature field measurement and balancing method and device for electronic thermometer calibration. The present invention includes a constant temperature water tank, a loading platform, a thermometer oblique insertion device, an L-shaped cylindrical scale rod, a liquid level detection switch and a temperature measurement balance device. A loading platform is arranged above the constant temperature water tank, and three thermometer oblique insertion devices are symmetrically arranged on the front and rear sides of the loading platform. The liquid level detection switch is fixed to the loading platform through an inverted L-shaped support frame; a linear module is installed on the loading platform, and the top surface of the loading grid is connected to the linear module through a connecting rod. An L-shaped glass cylindrical scale rod is fixed to one side of the loading platform through an inverted L-shaped support frame, and the tail end of the L-shaped glass cylindrical scale rod is connected to the water outlet at the bottom of the constant temperature water tank through a silicone tube. The present invention can ensure that the electronic thermometer and the thermometer are at the same calibration position and height, solve the problem of liquid level drop caused by water evaporation, and improve the temperature measurement accuracy of the thermometer during the calibration of the electronic thermometer.

A device and method for measuring the liquid volume of a flowback fluid in a well test

ActiveCN116067443BEasy to relieve pressureConvenient for sampling and measurementMachines/enginesLevel indicators
The present application belongs to the technical field of oil and gas testing and logging, and discloses a device and method for measuring the volume of flowback fluid in oil and gas testing and logging. The device comprises a buffer tank, which is provided with a liquid inlet, a liquid outlet, a liquid outlet and a gas release port. The liquid inlet is connected to the liquid outlet pipe of the flowback fluid, and the liquid outlet is provided with a liquid outlet pipe to communicate with the liquid pool. A partition is arranged in the buffer tank to divide the buffer tank into a first chamber and a second chamber. A liquid flow channel is arranged between the partition and the inner wall of the buffer tank to communicate the first chamber and the second chamber. A stirrer is arranged in the first chamber, and a liquid level meter is arranged in the second chamber. An electric ball valve is arranged on the liquid outlet pipe, and an electromagnetic flowmeter is arranged on the liquid outlet pipe between the liquid outlet and the electric ball valve. The present application sets the buffer tank and the partition, which facilitates the pressure relief of the flowback fluid and the obtaining of the liquid level height of the stable liquid. The present application realizes the continuous and smooth flow of the flowback fluid to achieve the purpose of accurately measuring the volume of the flowback fluid.
