The following provides a comprehensive introduction to the core advantages and application value of this product from multiple dimensions.
1、 Core Measurement Principles
Liaoning Xinruipeng Environmental ProtectionUltrasonic open channel flowmeterUsing self-developed ultrasonic time difference measurement technology, combined with ultrasonic echo ranging principle and fluid mechanics model, accurate and non-contact measurement of open channel flow is achieved. The core includes two key steps: liquid level measurement and flow conversion, and the entire process is digitized to ensure accurate and reliable data.
In the liquid level measurement process, the equipment emits high-frequency sound pulses (frequency range 50-200kHz) vertically towards the liquid level through an ultrasonic probe. The sound waves propagate at a speed of 331.4+0.6tm/s (t is the ambient temperature) in the air and reflect back to the probe after contacting the liquid level. The device accurately measures the time difference Δ t between transmission and reception, combined with real-time sound velocity, to calculate the distance D=v × Δ t/2 from the probe to the liquid level. Then, using the preset probe to the "zero liquid level" reference distance L, the real-time liquid level height H=L-D is finally obtained, with a liquid level resolution of up to 1mm and a measurement accuracy of ± 3mm. At the same time, the device has a built-in sound velocity compensation algorithm that can automatically correct the influence of temperature and humidity on sound velocity, avoiding measurement deviation caused by environmental factors.
In the flow conversion process, there is a non-linear relationship between open channel flow and liquid level. The equipment is equipped with various standard weir channels (such as Bacher channels, triangular weirs, rectangular weirs, etc.) to establish water level flow relationship models. The mathematical formula Q=C × H ⁿ (Q is flow rate, C is weir channel coefficient, n is index) that meets international and national standards is called to automatically convert real-time liquid level data into instantaneous flow rate and cumulative flow rate. For non-standard weir scenarios, a dedicated liquid level flow curve can be established through on-site calibration to further improve measurement accuracy. In addition, some models adopt multi-channel technology by installing multiple pairs of probes at different heights in the channel to synchronously measure the flow velocity of each channel. The weighted average algorithm is used to calculate the average flow velocity of the cross-section, reducing measurement errors and adapting to complex flow fields such as wide and shallow channels or non full pipes.
Compared to traditional contact measurement equipment, this product does not require direct contact with water bodies, avoiding problems such as sedimentation, attachment of aquatic organisms, corrosion and wear, significantly reducing maintenance costs, and achieving 24-hour uninterrupted monitoring to ensure the continuity and stability of data collection.
