Wuhan Shuicejia Wireless Plumb Bob Radar Flowmeter - Plumb Bob Cableway Radar Flow Measurement
02 Dec,2025
Product Introduction
The SCJ-LL21(LORA) Integrated Radar Flowmeter (Flow Velocity Meter) is a non-contact flow measurement device that utilizes the Doppler effect of electromagnetic waves to measure water flow velocity. It features an integrated signal processor and proprietary flow velocity calculation algorithms, enabling fast and accurate computation of water flow velocity without the need for calibration or drift correction. The device is equipped with a TFT LCD screen and a built-in lithium battery, allowing for rapid on-site measurement of surface water flow velocity data without manual calculations. It employs wireless LoRa communication and is widely used in applications such as drone-based flow measurement and plumb bob cableway flow measurement.
The SCJ-LL21(LORA) Integrated Radar Flowmeter (Flow Velocity Meter) consists of three components: a radar flowmeter probe, a wireless data collector, and a handheld terminal. The wireless data collector and handheld terminal are connected wirelessly.
Product Features
Utilizes imported Doppler radar antenna for high-precision flow velocity measurement.
Depending on the on-site environment, a 10-50m radar water level gauge can be optionally configured to measure the height from the device to the water surface.
Equipped with a built-in lithium battery and a standard Type-C USB port for connecting to a computer or charging.
Features an integrated keyboard and LCD screen, offering simple operation, intuitive readings, and direct output of results without the need for secondary calculations.
Provides high-precision flow velocity measurement with no drift and requires no calibration.
Includes a compatible bracket for easy installation onto existing plumb bobs, ensuring user-friendly deployment.
Comes with a wireless handheld device, enabling flow measurement to begin without the need for a computer.
Hydrological Measurement Case Study
In hydrological monitoring scenarios such as water census, river flood control, irrigation district scheduling, and environmental regulation, the accuracy, real-time capability, and adaptability of flow measurement equipment directly determine the scientific validity of management decisions. Traditional flow measurement devices often face limitations: some require immersion in water, leading to wear and corrosion; others rely on manual operation, resulting in low efficiency; while some suffer from data transmission delays, failing to meet the demands of dynamic monitoring.
As an innovative product that combines the stability of traditional plumb bob flow measurement with the advanced capabilities of modern radar technology, the Wireless Plumb Bob Radar Flowmeter addresses these challenges in complex aquatic environments. With its core advantages of "non-contact measurement + wireless transmission + high adaptability," it has become a key sensing device in the development of smart water management systems.
The Wireless Plumb Bob Radar Flowmeter is an integrated flow monitoring device developed based on Doppler radar technology and IoT transmission technology. Its design inspiration comes from the stable characteristics of traditional plumb bob flow meters, retaining a streamlined structure and counterweight design similar to that of a plumb bob to ensure the device maintains stable posture in turbulent water flow. At the same time, it abandons the contact-based measurement mode of traditional plumb bobs and adopts non-contact radar detection technology. Combined with a wireless communication module, it enables real-time collection and remote transmission of flow velocity, water level, and flow data.
In scenarios such as natural rivers and small-to-medium river basins, the wireless plumb bob radar flowmeter can monitor water level, flow velocity, and discharge changes in real time. Especially during heavy rainfall and flood seasons, it accurately captures flood peak discharge and the rate of water level rise, enabling real-time data reporting and anomaly warnings via a cloud platform.
