| Doppler aerial meter4420/4830It is a single point current meter, which is mainly used for integration into the Andra Marine Guardian platform, which can be used for both scientific research and commercial use.4830In addition to measuring the current, the temperature can also be measured simultaneously.4420/4830haveAI capandRS-232Two outputs, used when integrated into the Ocean Guard platformAI cap, used when used aloneRS-232Output.There are two other models of this current meter4420R/4830R, can be connected to longer cables for use alone,RS-422Output, cannot be integrated into the Ocean Guardian platform. | |||||
| Doppler aerial meter4420/4830Adopt the backscatter acoustic Doppler principle,It has two orthogonal sensor axes, each with two sensors, so bidirectional measurements can be performed on each axis, which is a great advantage of this sensor, which makes the sensor vortex to the periphery of the sensor when measuringInterference is insensitive (forward measurement enabled).With forward measurement enabled, only one sensor on each axis simultaneously sends acoustic pulses and receives acoustic pulses reflected from particles, thereby measuringXAxis heelYThe orthogonal velocity component of the axis is obtained after tilt compensation.passXAxis heelYMeasurement of the axis velocity vector and the orientation of the built-in solid-state electronic compass calculate the velocity components in the north and east directions. After multiple measurements, the output flow velocity and flow direction are averaged. | |||||
| Doppler aerial meter4420/4830useZ pulsetechnology,Z pulseThe advantage of the technology is that it can improve measurement accuracy.Complex acoustic pulse technology contains different frequencies in a single pulse, dividing the received signal into different frequency bands, each frequency band being transmitted to the processor as a primary pulse signal, using a high-speed digital processor and based onarm AParameter model algorithm analyzes the changes in Doppler frequency.This multi-frequency technology reduces while achieving the required accuracypingnumber of times.The measurement accuracy of the instrument andpingThe number of times is inversely proportional, andzPriceThe technology adopts two frequencies, which are to achieve the same accuracy compared to single frequencies.pingThe number of times is reduced to half of the single frequency. | |||||
| Doppler aerial meter4420/4830Very suitable for monitoring low-flow water bodies without moving particles, and because the instrument measurement area is away from the instrument0.4~1.0 No, the impact of pollution and turbulence is also minimal. | |||||
