摘要： A vortex flowmeter has first and second process connections with a meter inlet and outlet, respectively, therein. The first and second process connections are configured to connect, respectively, to upstream and downstream segments of a fluid pipeline. A fluid conveyance system conveys fluid from the inlet to the outlet and divides the fluid into separate fluid streams that flow through separate passages. Each of the passages has its own vortex metering unit configured to generate and detect vortices in the respective fluid stream. A processing system is configured to calculate a sum of the flow rates through all of the fluid streams.

摘要： A gas meter device of the present invention includes an inlet into which a fluid flows, and an outlet from which the fluid flows out, and is configured to derive a flow value of the fluid flowing from the inlet to the outlet. The gas meter device comprises plural measurement fluid passages provided in parallel between the inlet and the outlet; flow value measuring units provided in the plural measurement fluid passages, respectively, and configured to independently measure flow values of fluids flowing through the measurement fluid passages, respectively; an average flow value calculation unit configured to derive an average flow value of the flow values measured by the flow value measuring units, respectively; and a flow value comparison unit configured to obtain index values indicating a relation between the average flow value derived by the average flow value calculation unit and the flow values measured by the flow value measuring units, and determine whether or not each of the index values is equal to or larger than a predetermined value. Thereby, the present invention can determine whether or not there is an erroneous measurement flow value from only the separate flow values independently measured in the measurement fluid passages, respectively.

摘要： The apparatus for monitoring the delivery of fuel oil through a fuel oil delivery pipe including a flow meter and temperature sensor associated with the oil delivery pipe for measuring the temperature and flow rate of the fuel oil as it moves through the pipe. The digital output signals from the flow meter/temperature sensor are used to generate data signals which are a function of the measured temperature and flow rate parameters. A memory records the data signals. The actual total quantity of fuel oil delivered through the pipe is calculated based upon the data signals. A clock circuit generates a timing signal reflecting the date and time the measurements were taken. A transmission signal formed of the calculated actual total quantity of fuel oil delivered and time signal may be sent to a remote location by a WiFi transmitter or through the internet using a modem.

摘要： A method and a gas flow meter for measuring gas flow. A cylinder is supported in the flow meter with a horizontal orientation. A piston is disposed movably within the cylinder, the piston having a surface which forms a clearance seal with a surface of the cylinder. The piston may have a low-friction coating such as diamond-like carbon. A gas flow to be measured is received at a gas inlet, and directed to the cylinder so as to move the piston within the cylinder. The gas flow is directed by valves and conduits alternately to the two ends of the cylinder, for measuring the gas flow in both directions of the cylinder. From the detected movement of said piston electrical signals representative of the gas flow are generated.

摘要： A method for detecting complete or partial plugging of a measuring tube of a Coriolis flow measuring device, which is insertable into a pipeline, and which has a measuring transducer of the vibration type having at least two measuring tubes connected for parallel flow. The method includes, in such case, the steps of measuring a subset flow occurring in a subset of the measuring tubes, and comparing a subset flow value obtained from this measurement with a reference value to be expected for this subset. The reference value is, in such case, determined from a total mass flow determined in the context of a Coriolis mass flow measuring. Additionally, the method includes the step of detecting plugging of at least one measuring tube of the measuring transducer, if the subset flow value deviates from the reference value by more than a limit value.
