Handheld radar flow meter is a portable device that uses K-band radar for non-contact flow velocity measurement. It is compact and easy to operate. It is suitable for measuring the flow velocity of rivers, sewage, mud, and oceans, and is primarily used for hydrological surveys, engineering construction, and rapid measurements in emergency situations such as floods and dam breaches.
Handheld radar flow meter is an important portable device in the field of modern flow velocity measurement. It is mainly based on the Doppler radar principle, emitting radio waves of a specific frequency to the water surface and calculating the surface flow velocity by receiving and analyzing the frequency changes of the echoes reflected by floating objects or waves on the water surface. This non-contact measurement method offers significant advantages compared to traditional mechanical rotor-type flow meters.
The core features of Handheld radar flow meter are its portability and ease of operation. The device is designed to be handheld, compact, and lightweight, making it easy for measurement personnel to carry to various complex terrain areas. During use, the operator simply stands on a bridge, riverbank, or boat, points the instrument at the water surface to be measured, and starts the measurement. Flow velocity readings can be obtained within seconds. The entire process does not require placing any sensors in the water or setting up complex support systems.
In terms of technical applications, Handheld radar flow meter mainly serves three types of scenarios. The first is hydrological monitoring and field surveys. Hydrologists can use this device to quickly complete flow surveys of river cross-sections, monitor water volume in irrigation canals, and conduct field investigations, greatly improving work efficiency. The second is the construction and maintenance of various water-related projects. For example, in water conservancy construction, river channel regulation, port construction, or pipeline discharge monitoring, it can be used to quickly assess the impact of water flow conditions on the project. The third, and particularly valuable area, is emergency rescue measurement. In the event of floods, dam breaches, or mudslides, where the water flow is turbulent and the situation is dangerous, traditional contact measurement methods are often difficult to implement or pose safety risks. At this time, the non-contact and rapid measurement characteristics of the handheld radar flow meter make it the preferred tool for quickly measuring flood peak flow velocity and assessing the danger, providing critical data support for flood control command and decision-making.
In addition, Handheld radar flow meter has a wide range of adaptability to different types of water bodies. In addition to conventional rivers and channels, it can also be used to measure the surface flow velocity of domestic sewage, industrial wastewater, mud, and even ocean waves containing a large amount of impurities, solving the problem of measuring difficult-to-measure special fluids. This gives it a place in environmental monitoring, slurry transportation, and marine surveys.
In summary, Handheld radar flow meter, with its non-contact, fast, portable, and safe technical characteristics, has become an indispensable practical tool in hydrological monitoring, engineering construction, and emergency rescue. It is particularly suitable for situations requiring rapid response, harsh conditions, or where contact measurement is impossible, providing efficient and reliable flow velocity measurement solutions for relevant industries. With technological advancements, its measurement accuracy and stability are continuously improving, and its application scope will further expand.
