The KNF-132 acoustic Doppler flowmeter utilizes the Doppler effect of sound waves propagating in fluids to measure the velocity of the fluid by measuring the Doppler frequency shift generated by the scattering of sound waves by small particles and bubbles in the fluid. Combined with the liquid level data provided by the built-in diffusion silicon pressure sensor, the flow rate of the measured fluid is obtained using the velocity area method. Suitable for flow velocity and flow measurement in open channels, rivers, and non-standard sections, as well as flow velocity and flow measurement in various full and non full pipe scenarios.
Acoustic Doppler flowmeter has high accuracy, reliability, and intelligence, and is particularly suitable for monitoring sewage discharge, natural river flow, irrigation processes, water loss/depth, river and tidal research, coastal erosion research, seawater pastures, etc.

Integrated design, with multiple built-in sensors that can simultaneously measure data such as flow rate, liquid level, temperature, etc.
The flow data is measured based on the principle of velocity area method, with no head loss, and can be used in non-standard cross-sections.
The Doppler principle is used to measure flow velocity, which can meet the working conditions of low flow velocity and low liquid level.
No mechanical rotor structure, no disturbance to turbulent flow field, flow state.
Can measure instantaneous flow and cumulative flow.
The digital signal processing layer adopts the fast Fourier transform algorithm, which ensures stable and reliable measurement data.
Installation is simple and fast.
