When gases or liquids are transported for sale, the flow rate is often conveyed as BTU/day or GJ/hour. Theenergy flow rateequals: Volume flowrate X energy content/unit volume Or Mass flow rate X the energy content/unit mass While flow meters calculate the volumetric or mass flow rate, af...
PURPOSE:To correct the inertia error of a turbine meter, etc., which is generated when the valve of the pipe is closed, to make measure of an accurate flow rate possible by subtracting a prescribed quantity from the flow rate measure value according to the pressure in the pipe. CONSTITUTION...
In the case of lakes, it can be impractical to measure flows in all the streams entering the lake. If the total inflow for all streams is of interest, this can be assessed from the rate of change of the lake volume and the outflow. The rate of change of volume is estimated as the...
All Volume Flow Rate Units The volume flow rate units in the volume flow rate converter are acre foot/day, acre foot/hour, acre foot/minute, acre foot/second, acre inch/day, acre inch/hour, acre inch/minute, acre inch/second, barrel/day, barrel/hour, barrel/minute, barrel/second, barr...
The volume flow rateQis equal to the volume of liquid passedVdivided by the time passedt. To use this formula, you need to be able to measure the volume of liquid that passes in a given time. For example, let’s find the flow rate for a garden hose that can fill a 5-gallon bucke...
PROBLEM TO BE SOLVED: To provide a flow-rate measuring apparatus whose miniaturization is promoted by a method wherein a gas contained in a fluid is separated with a simple and compact constitution without using a buffer tank. ;SOLUTION: A centrifugation part 5 is installed. A three-phase flu...
PROBLEM TO BE SOLVED: To measure flow rate accurately regardless of the presence or absence of a pulsating flow.;SOLUTION: The flow rate-measuring instrument comprises a repetition means 11 for repeating transmission/reception between a transmitter 6a and a receiver 6b for transmitting or receiving ...
Thermal mass flowmeters are primarily used to measure the flow rate of gases. The structure of the device is shown in Fig. 16.3. The principle of operation is to direct the flowing material past a heated element and measure the temperature of the flowing material before and after the heater...
Oil, gas, and water flow rate in real-time – measurement becomes multiphase The VIS multiphase flowmeter measures real-time flow rates of oil, gas and water in the most difficult multiphase environments that are typical of the oil and gas upstream sector - Measurement made eas...
A volumetric flowrateQof a liquid or a gas being transported in the pipeline is defined as an amount of a liquid or a gas flowing through cross-sectionSof the spoolpiece per unit time. Forsteady flow, the flowrate is determined as
