Self-recording flow meter measurement principle

Measuring principle

Flow rate measurement: The flow meter is driven by water and its built-in signal device generates a revolution signal. Thus, the flow rate can be calculated from the following formula based on the total number of signals generated by the flow meter during a certain unit period:

(m/s)

In the formula: v—average flow velocity (m/s) during the measurement period

B—rotor (or cup) hydraulic pitch (m)

a—Flowmeter constant (m/s)

T—Flow duration (s)

The total number of revolutions of the flow meter rotor during the R-T period

For an individual flow meter, b and a are constant 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 measured section type, and manually input (or measured by auxiliary sensor) the water level and width of the regular section to calculate the cross-sectional area, the meter has Q=V*S to measure the flow rate Q value

HSY type Electric Hoist is a small light Lifting Equipment. Its lifting range ranges from 500kg to 25 tons according to customer requirements.

The electric hoist can be divided into hoist type chain crane, chain hoist with manual trolley, chain hoist with electric car, Low Headroom Chain Hoist.

Widely used for lifting, loading and unloading, repair equipment, lifting cargo.

It is installed on suspended I-beam, curved track, cantilever crane rail and fixed lifting hoisting.
