摘要： In order to extract a part of a three-phase flow from a pipe line (23), a pair of communication pipes (13), which are connected to upstream and downstream sides of an orifice (12) provided in the pipe line (23), and a gas-liquid extraction tank (14) are used. Flowing of a slag flow or the like into the pipe line (23) causes a periodical change in a pressure difference between input and output sides of the orifice (12). This causes extraction of gas-liquid and discharge mainly of gas to be simultaneously effected in the pair of communication pipes (13) and the gas-liquid extraction tank (14). Within the gas-liquid extraction tank (14), the gas-liquid is forcibly shaken horizontally, vertically, etc. for agitating, whereby gas-liquid of high liquid-phase rate remains. Then, the gas is removed from this gas-liquid of high liquid-phase rate to thereby extract mixture liquid, which is accumulated in a liquid storage tank (17). The mixture liquid flows from the liquid storage tank (17) in an amount required at a Coriolis meter (38). As a result, high precision density measurement is performed at the Coriolis meter (38).

摘要： A process pressure fluid transmitter is coupled to a differential pressure producer and measures a differential pressure across the producer. A statistical parameter is calculated upon successive differential pressure indications, and the calculated parameter is used to indicate wet gas flow. The indication can be generated locally at the process pressure transmitter, communicated via a wired process communication loop, communicated wirelessly, or any combination thereof.

摘要： A method of monitoring a fuel stream (F) flowing from a fuel storage tank (4), through a fuel line (3) and to a fuel dispensing nozzle (6) of a fuel dispensing unit (1). The method comprises the steps of: generating a variation of the flow of the fuel stream (F), said variation based on the amount of gaseous fluid in the fuel stream (F), detecting the variation of the flow of the fuel stream (F), and determining if the detected variation exceeds a specific level.

摘要： A prior art device for determining at least one parameter of a flowing gas-liquid mixture has a drawback in that it does not offer any protection against liquids that move counter to the main direction of flow. The inventive device (50) has a condensation trap (36), which is arranged downstream from the measuring element (25) thus protecting the measuring element (25) against backward flowing liquids. The device is used, in particular, for determining parameters of intake air in internal combustion engines.

摘要： A high void fraction multi-phase fluid flow meter and method, wherein a first fluid flow path including a multi-phase flow measuring device disposed in series with a liquid flow restrictor is provided in parallel with a second fluid flow path including a gas flow measuring device. The presence of liquid flow in the flow meter is detected. When liquid flow is detected, a valve in the second fluid flow path operates to cut off fluid flow through the second fluid flow path. Otherwise the valve in the second fluid flow path operates to divert gas flow through the second fluid flow path. Alternatively, a negative pressure differential is produced across the second fluid flow path when liquid flow is present, by passing the incoming liquid flow through a jet pump nozzle, to prevent liquid flow into the second fluid flow path. A check valve is then disposed in the second fluid flow path to prevent backflow from the output of the multi-flow measuring device into the second fluid flow path. A computer outputs an indication of the liquid flow, typically oil flow and water flow, through the multi-phase flow meter, and the combined total amount of gas flow through the two flow meters.
