Measuring principle of self-recording flowmeter

Abstract: The information on the measurement principle of the self-recording flowmeter is provided by the excellent flowmeter and flowmeter manufacturers. Flow rate measurement: The flow meter is driven by water, and its built-in signal device generates a signal of the number of revolutions. Therefore, according to the total number of signals generated by the flow meter in a certain unit period, the flow velocity can be calculated by the following formula: (m/s) Where: v Average flow velocity in the flow measurement period. For more flowmeter manufacturers to select models and price quotations, you are welcome to inquire. The following is the details of the measurement principle of the self-recording flowmeter. Flow rate measurement: The flow meter is driven by water, and its built-in signal device generates a signal of the number of revolutions. Therefore, the flow velocity can be calculated by the following formula according to the total number of signals generated by the flow meter in a certain unit period: (m/s) In the formula: v—Average velocity (m/s) b during the flow measurement period—Propeller (or cup) hydraulic pitch (m) a—Flow meter constant (m/s) T—Flow measurement duration (s) R—The total number of revolutions of the flowmeter rotor in the T period For a certain individual flowmeter, b and a are fixed values. Therefore, when measuring the flow, as long as the T and R values ​​are measured, the flow rate can be calculated. Flow measurement: input the type of the section to be measured, and manually input (or measure by auxiliary sensor) the water level and width of the regular section to calculate the section area, the meter has more Q=V*S to measure the flow velocity Q value The above is the whole content of this article, welcome to call Consult our factory for flowmeter selection, quotation, etc. 'Measuring principle of self-recording flowmeter'
