| The Doppler inverter acoustic Doppler principle adopts the backscattering acoustic Doppler principle, which has two orthogonal sensor axes, with two sensors on each axis.This allows it to perform bidirectional measurements on each sensor axis, and by turning on the forward measurement function, the interference of the eddy current around the sensor and the anchor chain can be greatly reduced.After enabling the forward measurement function, only one sensor on each axis sends acoustic pulses and receives acoustic pulses reflected from the particles, thereby measuring the orthogonal velocity components of the X-axis and Y-axis. After tilt compensation, the horizontal velocity is obtained.Component.The velocity components of the north and east directions are calculated by measuring the X-axis and Y-axis velocity vectors and the direction of the built-in solid-state electronic compass. After multiple measurements, the output flow velocity and flow direction are calculated. | ||||||||||
| Another great advantage of the instrument is that the instrument adopts advanced ZPulse technology, which improves the statistical accuracy of the measurement.Complex acoustic pulse techniques contain different frequencies in a single pulse.The received signal is divided into different frequency bands, each frequency band is transmitted to the processor as a primary pulse signal, and the changes in Doppler frequency are analyzed using a high-speed digital processor and an ARMA parameter model algorithm based on the algorithm.This multi-frequency technology reduces the number of pulses while achieving the required accuracy.During a measurement cycle, the instrument measurement accuracy is proportional to the reciprocal of the square helix of the pulse number.ZPulse technology Doppler current meter uses dual-frequency pulses, which can reduce the number of pulses to half of the single frequency when the required measurement accuracy is achieved, thereby greatly extending the battery life or shortening the measurement cycle for the same battery life, and obtaining moredata. | ||||||||||
