+86 15898932201This handheld radio current meter uses K-band radar for non-contact flow velocity measurement of rivers, sewage, mud, and oceans. With a measurement range of 0.1 to 30 meters per second, it is applicable to scenarios such as canal and river management, flood control, sewage discharge, and railway bridge construction, solving the problems of interference from sediment and corrosion from sewage in traditional measurements.
The handheld radio current meter is a non-contact instrument that uses the Doppler principle of K-band radar to measure flow velocity. The device emits a microwave beam to the water surface and receives the echo reflected from the water surface. The flow velocity is calculated through frequency shift. This measurement method does not require entry into the water body and can measure the flow velocity of various fluids such as rivers, sewage, mud, and oceans within a range of 0.1 to 30 meters per second, suitable for various complex hydrological environments.
In terms of technical parameters, the handheld radio current meter operates at a frequency of 24.15 GHz (K-band), belonging to the industrial, scientific, and medical frequency bands, with a measurement range of 0.1 to 30 meters per second. The device employs a built-in angle sensor to automatically compensate for the influence of the angle between the radar wave and the water flow direction on the flow velocity measurement results, eliminating the need for manual angle input. The instrument features peak detection, automatically capturing the maximum flow velocity, and also supports a manual measurement mode. The display interface uses a high-brightness color screen, allowing for clear data reading even in strong light. A built-in high-capacity lithium battery provides over 8 hours of continuous operation and supports USB charging. With an IP67 protection rating, it can withstand harsh environments such as rain and splashes.
This handheld radio wave current meter has wide applications in various scenarios. In channel and river flow velocity monitoring, it is suitable for daily flow measurements at hydrological stations, water resource surveys, and riverbed evolution analysis. In sewage flow velocity monitoring, it can be used for flow calculation at urban sewage pipe networks, sewage treatment plant inlets, and outlets; due to its non-contact measurement method, it avoids corrosion and clogging problems caused by sewage to the sensor. In ocean current velocity monitoring, it can be used for nearshore current surveys, tidal studies, and marine engineering hydrological observations. In railway bridge construction, this device can be used for monitoring water flow scour during pier construction, measuring flow velocity during construction diversion, and conducting temporary hydrological surveys. In flood control and disaster relief emergency monitoring, this equipment can be rapidly deployed to track peak flow velocity in real time, providing data support for flood control decisions. Furthermore, the handheld electromagnetic current meter is also suitable for debris flow early warning, flash flood surveys, soil and water conservation monitoring, and other occasions requiring on-site measurements.
The main advantage of the handheld electromagnetic current meter is that it solves the problems of interference from sediment and corrosion from sewage in traditional contact-based flow velocity measurement methods. Traditional rotor-type current meters or acoustic Doppler point current meters require immersing the sensor in water, which is easily damaged or clogged in environments with high sediment content, abundant floating debris, or highly corrosive sewage. The handheld electromagnetic current meter measures water surface velocity from the air by emitting electromagnetic waves, without contact with the water body, and is unaffected by suspended solids, chemicals, or oil in the water, allowing for long-term stable use in harsh water quality environments. At the same time, the instrument is lightweight and portable, can be operated by a single person, and does not require wading during measurement, improving operational safety and measurement efficiency. The device can store multiple sets of measurement data and supports Bluetooth transmission to a mobile app or computer software for post-processing and analysis, meeting the requirements of modern hydrological monitoring for data automation and informatization.
