Ultrasonic Flow Meter – Non-Invasive, High-Precision Water Measurement for Agriculture
Accurate flow measurement is the foundation of effective irrigation management. Shandong Jintian‘s ultrasonic flow meter utilizes advanced transit-time ultrasonic technology to deliver precise, real-time measurement of water flow in pipelines. Whether deployed for high-efficiency irrigation projects, agricultural water pricing reform, or smart water conservancy networks, our flow meter provides the data needed to optimize water usage, ensure fair billing, and support sustainable agriculture.
As part of Shandong Jintian’s integrated water management platform, the ultrasonic flow meter works seamlessly with our RF card controllers, smart water price processors, and data acquisition systems. With over 23 years of experience and authorship of China National Standard GB/T 40119-2021, our intelligent flow measurement solutions are trusted by more than 700,000 water users across nearly 4,000 villages nationwide.
How It Works
The transit-time ultrasonic flow meter operates on a simple yet highly reliable principle. Two ultrasonic transducers are mounted on the pipe – one upstream, one downstream. The transducers alternately transmit and receive ultrasonic signals. When there is no flow, the transit time in both directions is equal. When water flows, the downstream signal travels faster, while the upstream signal travels slower. The difference in transit time is directly proportional to the flow velocity, allowing the meter to calculate both instantaneous flow rate and total accumulated volume.
Our flow meters measure in a non-contact manner, eliminating moving parts, pressure drop, and maintenance issues associated with mechanical meters.
Key Features & Benefits
-
Non-Invasive, Clamp-On Installation – External transducers eliminate pipe cutting, pressure loss, and leak points. One meter can be used at multiple locations.
-
High Accuracy, No Moving Parts – Transit-time technology delivers accuracy of ±1% to ±2% with no mechanical components to wear, jam, or corrode.
-
Ultra-Low Flow Sensitivity – Capable of measuring very low flow rates, enabling precise detection of even small leaks or low-velocity flow.
-
Low Power Consumption – Optimized for remote field installations and solar-powered applications.
-
Bidirectional Measurement – Measures flow in both forward and reverse directions, with clear LCD display of flow rate, direction, and total accumulation.
-
Wide Operating Range – Reliable performance from -20°C to +70°C, IP68-rated housing ensures operation in severe environments.
-
Multiple Communication Options – RS485 digital output for seamless connection to remote monitoring systems, RF card controllers, and smart water price processors.
-
Suitable for Varied Water Quality – Unaffected by sand, gravel, algae, or weeds, ensuring stable measurement even in raw irrigation water.
