摘要： A leakage detector for a fuel vapor processing system includes a pressure sensor and a control unit. The pressure sensor is configured to measure an internal pressure of the fuel vapor processing system. The control unit is configured to calculate changes of a fuel vapor pressure from a saturation vapor pressure curve of the fuel vapor, a fuel vapor concentration of the fuel vapor in a gaseous layer within the fuel vapor processing system, and a convective velocity in the gaseous layer, to correct a reference pressure for leakage detection based on the changes of the fuel vapor pressure so as to calculate a corrected reference pressure, and to compare the internal pressure measured by the first pressure sensor to the corrected reference pressure so as to determine whether any of the fuel vapor has leaked from the fuel vapor processing system.

摘要： A liquid sensor includes a light receiver configured to receive light. The light receiver is attachable to an outside of an accommodation unit into which a liquid is introduced and which has translucency. The light receiver receives light that has passed through the liquid in the accommodation unit or light reflected by the liquid, and outputs a signal related to a physical quantity of the liquid.

摘要： An in-situ detection device for detecting water and fertilizer content in a crop cultivation substrate and a detection method thereof are provided. The in-situ detection device includes a water and fertilizer in-situ collector and a spectrum analysis device. The water and fertilizer in-situ collector that is pre-buried in the cultivation substrate is used to collect water and fertilizer in the cultivation substrate in real time to obtain a measurement sample. The spectral analysis device is used to emit a laser with a specific wavelength to detect and analyze content of nitrogen, phosphorus, and potassium in the measurement sample collected by the water and fertilizer in-situ collector; and a continuous sampling system for continuously transporting the measurement sample is provided between the water and fertilizer in-situ collector and the spectrum analysis device.

摘要： A wellbore fluid monitoring system includes a housing, a first sealing element, a second sealing element and a sealing unit. The housing is configured to be securely disposed in a portion of an annulus within a bell nipple below a rotary table of a wellbore drilling assembly. The annulus is formed by a drill string of the wellbore drilling assembly and an inner wall of a wellbore being drilled by the wellbore drilling assembly. The housing includes a first open end and a second open end. The housing is configured to house an air flow sensor disposed within the housing. The first sealing element is attached to the first open end of the housing. The first sealing element is configured to seal and unseal the first open end. The second sealing element is attached to the second open end of the housing. The second sealing element is configured to seal and unseal the second open end. The sealing unit is disposed in the portion of the annulus. The sealing unit is connected to the housing, the first sealing element and the second sealing element. The sealing unit is configured to actuate the first sealing element and the second sealing element to seal or unseal the first open end and the second open end, respectively, based on a liquid level in the portion of the annulus.

摘要： A redundant level measuring system comprises comprising a chamber for fluidic coupling to a process vessel whereby material level in the vessel equalizes with material level in the chamber. A float including a magnet in the chamber interior space rises and falls with material level in the chamber. The float comprises an inner cylindrical wall defining an elongate through opening. A magnet actuated visual indicator is mounted to the chamber for indicating level of the magnet in the chamber. A level measurement instrument includes a measurement circuit and a coaxial probe having an inner rod and a coaxial outer tube. The probe defines a transmission line and the coaxial outer tube has a through opening so that material level in the chamber equalizes with material level in the coaxial outer tube. The instrument is mounted atop the chamber with the probe directed downwardly to the chamber interior space and extending through the float through opening. The measurement circuit generates and receives a frequency signal on the transmission line, the measurement circuit measuring level of the material in the coaxial outer tube.
