2. What is the maximum ultrasonic flow rate

The actual flow upper limit of the maximum ultrasonic flowmeter depends on the pipe diameter size. Currently, the maximum nominal pipe diameter of industrial grade products can reach 6000mm, and the theoretical instantaneous flow rate can reach hundreds of thousands of cubic meters per hour when the pipe is full. 1. The maximum flow rate of the core parameters and typical specifications ultrasonic flowmeter is directly related to the pipe diameter, and the larger the pipe diameter, the greater the flow rate. The following are the flow capacity references for common large-diameter models (based on the principle of time difference method, liquid medium): | Pipe diameter (mm) | Maximum flow velocity (m/s) | Theoretical maximum flow rate (m ³/h) | Typical application scenarios | |: --- |: --- |: --- |: --- | 2000 | 12 | 135716 | Large scale water conservancy projects, raw water transportation | | 3000 | 12 | 305362 | Power plant circulating water, regional water transfer | | 4000 | 10 | 452389 | Municipal water supply main pipeline and spike network | | 6000 | 10 | 1017876 | Large flow water transmission pipelines, industrial discharge channels | Note: Theoretical flow is calculated based on full pipes and circular pipes (flow rate=flow velocity x pipeline cross-sectional area). The actual maximum flow rate is limited by installation conditions, medium characteristics, and the measurement range of the product itself. 2. The key factor affecting the maximum flow rate is the size of the pipeline, which is the determining factor. There are customized products on the market that can measure pipe diameters of DN6000 and above, such as KROHNEs OPTI

SONIC 7400 from Germany and Endress+Hausers Prosonic Flow T series from Switzerland. Installation method: The upper limit of flow measurement for external clamp sensors is usually lower than that of plug-in or pipe segment sensors, as they are more affected by pipe wall material, lining, and coupling conditions. Medium type: When measuring gases, due to the slow propagation speed and large attenuation of sound waves in gases, their maximum measurable flow rate is much lower than that of liquids. Sensor performance: High performance sensors and advanced signal processing technology can ensure measurement accuracy and stability under large pipe diameters, low flow rates, or harsh working conditions. Selection and application recommendations: For ultra large flow applications, multi-channel time difference ultrasonic flow meters are preferred. It can effectively compensate for the problem of uneven flow velocity distribution through multiple sound path cross measurements, with higher accuracy, especially suitable for large-diameter pipelines. When selecting, detailed operating parameters must be provided to the supplier, including medium, pipe diameter, material, lining, temperature, pressure, expected flow range, and Zaibu accuracy requirements. The manufacturer will conduct simulation calculations to confirm whether the final model is suitable. For non full pipe or open channel flow measurement, a dedicated Doppler method or open channel flow meter should be used, and the definition of the flow upper limit is completely different.
