Instrument Overview

The handheld electromagnetic current meter is an advanced instrument for measuring water velocity. It employs radar technology to enable simple, quick, and non-contact measurement of surface water flow rates. The instrument is compact and lightweight, making it easy to carry and ideal for field measurements in environments where submerged instruments are difficult or impractical to use, such as areas prone to flooding or fast-flowing waters.

Product Features

(1) Three measurement modes: single measurement / continuous measurement / average measurement

(2) Automatic correction of angles in both horizontal and vertical directions

(3) Built-in high-capacity lithium-ion battery, allowing continuous use for over 10 hours.

(4) Display flow velocity, flow rate, elevation angle, azimuth angle, area, and water depth.
