Handheld Flow Meter

Handheld Flow Meter Product Introduction:

LS300-B Handheld Flow Meter (portable flow meter for short) is specially developed for open channel flow velocity and flow measurement in the field by hydrological stations, factories and mines, environmental monitoring stations, farmland irrigation and drainage, hydrogeological surveys and other departments.

LS300-B Handheld Flow Meter can be used with flow velocity sensor, the propeller helix angle, pitch, manufacturing process and materials of which have been redesigned. It can measure open channel flow velocity and flow rate and other parameters.

Handheld Flow Meter Equipment List:

①Flow rate sensor, ②Signal connector, ③Flow rate calculator, ④Charging head, ⑤Data cable

Handheld Flow Meter Device Parameters:

Handheld Flow Meter measurement principle:

Flow velocity measurement: When the flow meter is driven by water, its built-in signal device generates a rotation signal. Therefore, the flow velocity can be calculated according to the total number of signals generated by the flow meter within a certain unit period of time by the following formula: v=a+b*R/T (m/s) (automatic calculation)

v--Average flow velocity during the flow measurement period (m/s)

b- propeller (or cup) hydraulic pitch (m)

a-flowmeter constant (m/s)

T-flow measurement duration (s)

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

For a certain individual flow meter, b and a are constant values. Therefore, when measuring flow, as long as the T and R values are measured, the flow rate can be calculated.

Flow measurement: Input the type of section to be measured, and manually input (or measure through auxiliary sensors) the water level and width of the regular section to calculate the cross-sectional area. The instrument can calculate the flow velocity Q value according to Q=V*S.
