Handheld Flow Meter

Portable Flow Meter Product Introduction:

Handheld Flow Meter is ideal for water flow studies and flow measurements in rivers, streams, canals and sewers, providing accurate water flow rates.The LS300-B Portable Flow Meter (referred to as portable flowmeter) is specially developed for open channel flow rate measurements in the field by hydrological stations, factories and mines, environmental monitoring stations, farmland drainage and irrigation, hydrogeological survey and other departments.

The LS300-B Portable Flow Meter can be used with a flow rate sensor. The sensor has been redesigned separately for the helical angle, pitch, production process and materials. Measure parameters such as open channel flow rate and flow.

Portable Flow Meter device list:

① Flow rate sensor, ② signal connector, ③ flow rate calculator, ④ charging head, ⑤ data cable

Portable Flow Meter device parameters:

Portable Flow Meter measurement principle:

Flow velocity measurement: Under hydraulic push, the flow velocity meter has a built-in signal device that generates a revolution signal. Therefore, the flow rate can be calculated from the following formula based on the total number of signals generated by the flow meter in a certain unit time period: v=a+b*R/T(m/s) (automatically calculated)

v1 average flow velocity (m/s) during the flow period

b A propeller (or rotary cup) hydraulic pitch (m)

aFirst-flow velocity meter constant (m/s)

T-test flow time (s)

Total number of rotations of flow meter rotor in R-T period

For a certain 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: Enter the type of section to be measured, and manually input (or measured through auxiliary sensors) the water level and width of the regular section to calculate the cross-section area. The instrument has Q=V*S to calculate the flow rate Q value
