Experimental Wave Tank Wave Gauge Enabling High-Precision Measurement of Wave Parameters

Experimental Wave Tank Wave Gauge integrates capacitive or ultrasonic sensing technologies to precisely measure wave parameters and water levels in free-surface fluids. Characterized by extremely low power consumption and excellent linearity, this device offers high precision and rapid response capabilities. Its non-contact mechanical design ensures exceptional reliability, making it a specialized instrument for accurately capturing wave motion characteristics in experimental research within the fields of hydraulic and ocean engineering.

Experimental Wave Tank Wave Gauge serves as a critical piece of equipment specifically designed for experimental research in fields such as hydraulic engineering and ocean engineering. Its primary function is to accurately capture wave motion parameters and fluctuations in water level on the surface of free fluids. The design of this instrument takes full account of the unique conditions inherent in experimental environments, utilizing advanced sensing technologies to achieve precise recording and analysis of wave characteristics.

In terms of measurement principles, Experimental Wave Tank Wave Gauge primarily employs capacitive or ultrasonic sensing technologies. Capacitive wave height sensors utilize the water body itself as an electrolyte; as the water level fluctuates, the capacitance value between the submerged electrodes changes correspondingly, allowing for the precise determination of wave height data through the measurement of this variation. These sensors typically integrate low-power microprocessors and high-precision 24-bit analog-to-digital converters (ADCs), enabling them to resolve minute changes in liquid levels with a resolution reaching 0.1 mm or higher, and maintaining a measurement accuracy within ±0.1% of the full scale (F.S.). Ultrasonic sensors, conversely, calculate water levels by measuring the time difference between the emission of an ultrasonic pulse and the reception of the signal reflected off the water surface. This method enables non-contact measurement, making it particularly well-suited for measuring steep waves, breaking waves, and high-velocity waves, and capable of handling wave conditions involving relative velocities of up to 15 meters per second.

The application scope of Experimental Wave Tank Wave Gauge spans multiple domains within hydraulic and ocean engineering research. In physical model experiments involving hydraulic structures—such as ports, navigation channels, ship locks, and dams—this device is utilized to measure critical parameters including water level fluctuations, wave run-up heights, and the precipitation intensity resulting from spillway atomization. Furthermore, in wave flumes and towing tanks used for ship model testing, it serves to monitor three-dimensional hydraulic models, evaluate ship navigation performance, and validate the efficacy of active wave absorption systems. For marine engineering research, Experimental Wave Tank Wave Gauge provides reliable data support for the performance optimization of wave energy conversion devices, structural safety assessments of offshore platforms, and stability testing of breakwaters.
