This paper contains information like acoustic current, instruments, current meter, accuracy, current measurement technique, ocean wave measurement, high accuracy, and instrument. Inside this paper you can find things such as acoustic, current, accelerometer, tilt sensor, flow direction, pressure sensor, acoustic current meter, and real time.
Lots of information related to microcontroller, measurements, sensor, magnetic field, the current measurement, measurement, wave, and power consumption are explained inside the paper. Here are selected from the paper:
Applications of an Acoustic Current Measurement Technique Andrew L. All three instruments use Falmouth Scientific’s acoustic current measurement technique, which is based on measuring and comparing direct path acoustic phase shifts along multiple paths. MEMORY (1 MB FLASH) MICROCONTROLLER (WITH REAL-TIME CLOCK) SOLID STATE THERMOMETER SOLID STATE COMPASS SOLID STATE ACCELEROMETER Figure 5 2D-ACM hardware outline ACOUSTIC CURRENT VELOCITY MEASUREMENT Solid state compasses and accelerometers used in the 2D-ACM are surface mount components with small form factors.
Even more, the paper contains more around wave measurement, current measurement, acoustic transceivers, high accuracy current, wave parameters, transceivers, sampling rate, and current flow.
