Overview
Portable flow meters do not require complex calibration, and non professionals can quickly get started. Supporting vertical and horizontal installation, the directional device structure is reasonable and can cater to the direction of water flow, reducing measurement errors. The protection level reaches IP67, suitable for harsh conditions such as rainy days and mud. Monitor the water flow velocity in engineering areas such as river regulation and dam construction, evaluate the impact of construction on flood discharge capacity, and avoid foundation pit collapse or dam leakage.

Portable flowmeterNo need for complex calibration, non professionals can quickly get started. Supporting vertical and horizontal installation, the directional device structure is reasonable and can cater to the direction of water flow, reducing measurement errors. The protection level reaches IP67, suitable for harsh conditions such as rainy days and mud. Monitor the water flow velocity in engineering areas such as river regulation and dam construction, evaluate the impact of construction on flood discharge capacity, and avoid foundation pit collapse or dam leakage.
The LS300-B portable flow meter (referred to as the portable flow meter) is specially developed for measuring open channel flow velocity and flow in the field by hydrological stations, factories and mines, environmental monitoring stations, agricultural drainage and irrigation, hydrogeological surveys and other departments.
LS300-B typePortable flowmeterCan be used in conjunction with a flow rate sensor, which has been redesigned for the helix angle, pitch, manufacturing process, and materials of the propeller. Measure parameters such as flow velocity and flow rate in open channels.

Measurement principle:
Flow velocity measurement: Under hydraulic propulsion, the flow velocity meter has a built-in signal device that generates a rotational speed signal. Therefore, the flow velocity can be calculated based on the total number of signals generated by the flowmeter during a certain unit period using the following formula: v=a+b * R/T (m/s) (automatically calculated)
Average flow velocity during the flow measurement period (m/s)
B-type propeller (or cup) hydraulic pitch (m)
A - Velocity meter constant (m/s)
T-flow measurement duration (s)
The total number of revolutions of the rotor of the flowmeter during the R-T period
For an individual flowmeter, b and a are constant values. Therefore, when measuring flow, as long as T and R values are measured, the flow velocity can be calculated.
Flow measurement: Enter the type of the measured section and manually input (or measure through auxiliary sensors) the water level and width of the regular section to calculate the section area. The instrument also has Q=V * S to calculate the flow velocity Q value
