Product details

Instrument Overview

The flow velocity and discharge meter is a key complementary product for traditional rotor-type flow velocity instruments. It is used to receive signals generated by the flow velocity meter over a specified time period and automatically calculate the average flow velocity and discharge for that period. Additional expandable functions include measuring water level and computing the cross-sectional area of regular shapes. This instrument is widely applicable in various industries and sectors—such as hydrological surveys, hydraulic investigations, agricultural irrigation, and runoff experiments—for monitoring related flow velocity or discharge data.

Product Features

(1) It consists of a propeller, rotating components, bearings, tail assembly, and other parts.

(2) The propeller rotates around a horizontal support shaft driven by the water flow, generating on-off signals via reed switches to measure the flow velocity.

(3) Uses magnetically triggered switch contacts to generate on-off signals, producing two signals per revolution, suitable for various automated measurement systems.
