摘要： A method and apparatus for remote laser-based detection of gas at levels exceeding natural background levels preferably utilizing wavelength modulated tunable diode laser absorption spectroscopy. In a preferred embodiment, background gas and noise are estimated using statistical moving average and variance calculations. Gas concentration length measurements resulting from the spectroscopy are preferably compared in real-time or near-real-time to the sum of the background and noise estimates and an alarm limit to detect gas presence of concern. Gas levels exceeding this detection threshold are preferably indicated by a prolonged output tone with a pitch indicative of the magnitude of the gas measurement, and gas levels below the detection threshold are preferably indicated by silence.

摘要： A container of a dialysis machine has a determined shape and a known volume occupied in part by a volume of a mass of blood; a remaining part is occupied by a volume of a mass of gas. A disturbance is induced in a combined mass of the liquid and the gas in the container and an entity of the disturbance is measured. Measurements of pressure in the container before and after the disturbance are taken, the volume of gas is calculated using a function correlated to a gas law, and the volume and level of the liquid in the container are derived after the volume occupied by the gas is calculated.

摘要： A measurement system and a measurement method that are capable of accurately measuring liquid fuel stored in a container. When the air pressure within a first container (3) is less than a predetermined pressure, air is supplied into the first container (3) through a first pipeline (13) by a pressure application means (6). Also, both the volume of the supplied air and a quantity of change in the air pressure within the first container (3) due to the air supply are detected or calculated, and the volume of the liquid fuel within the first container (3) is calculated from both the volume of the supplied air and the quantity of change in the air pressure. When the liquid fuel within a second container (4) is less than a predetermined quantity, a predetermined quantity of liquid fuel is fed from the first container (3) into said second container (4) through the second pipeline (12) by a feed means (8), and the volume of the liquid fuel within the first container (3) is calculated based on the number of times that the liquid fuel was fed. Therefore, a liquid fuel quantity supplied from the first container (3) into the second container (4) can be accurately grasped regardless of shape and tilt of the first container (3).

摘要： A dual-phase level monitoring (DPLM) instrument that provides continuous signals that enables determination of the location of the top surface of the lighter of two immiscible fluids (the product) and the hydrostatic pressure below the total fluid column of both immiscible fluids. By knowing the fluid specific gravities, the output signals are processed to yield the location of the air/product and liquid/liquid interfaces, and the depth of the lighter phase. The instrument is intended for use in groundwater monitoring wells with a light non-aqueous phase liquid (product) and tanks or vessels with dual-phase liquids and level monitoring and/or control issues. The DPLM instrument includes a first pressure transducer situated beneath the surface of the liquid with a greater specific gravity, which will typically be ground water. A level element with a float selected so as to be buoyant and float on the surface of the lighter fluid is positioned above the first pressure transducer. A signal from the level element is proportional to the position of the float or the total distance the float is positioned above the bottom of the level element and therefore the total distance above the first pressure transducer, the pressure transducer located in the heaver liquid phase. A second pressure transducer can be deployed above the surface of the liquid if greater accuracy of measurement (as compared to assuming ambient pressure) is desired.

摘要： An ALC circuit is turned on (S1), a nozzle is shifted to a sampling position (S2), and after the ALC circuit has been turned off (S3), the nozzle is allowed to start discharging air from its tip (S4). While the nozzle is being lowered, the inner pressure of the nozzle is monitored (S5, S6), and upon detection of an increase in the pressure, the discharging process of air and the nozzle lowering process are stopped (S7), while the monitoring of the magnitude of the pressure is continued (S8). When the magnitude of the pressure is being maintained within a permissible range of the change for a predetermined time, it is judged that the tip of the nozzle has come into contact with the true liquid level, and after a suction operation of a sample (S9), the nozzle is raised (S10). When the magnitude of the pressure has dropped below the permissible range of the change within the predetermined time, it is judged that the tip of the nozzle has not come into contact with the true liquid level, the nozzle is again lowered (S11).
