Wave gauge system

1.Introduction to Wave gauge system

Wave gauge system is a simple and reliable device used to measure rapidly changing water levels in physical models and estimate wave energy.he Wave gauge system uses a low-power microprocessor, a 24-bit high-precision AD converter and a long-distance communication technology with a capacitive wave height sensor, which has good linearity, low power consumption, high quantity accuracy, long transmission distance, stable performance and strong anti-interference ability.The sensor adopts an integrated structure, which is simple and convenient to install.It has a USB interface that directly draws power from the USB port, no external power supply is required, and data acquisition equipment is flexible and convenient to install.Mainly used to measure free fluid waves, water level height, etc.It can be used for independent working mode (the maximum sampling rate is 1000Hz), or it can be used through RS485 networking.The networking mode can collect up to 128 measurement points at the same time.Run the sensor acquisition software to display and save waveform data in real time on the computer.Computer software displays, monitors and stores measurement process curves, and data files support TXT format and EXCELL file format output.

2.Product features of Wave gauge system

Digitalization: Digital output, no other acquisition equipment is required, and the wave height time curve is displayed when connected to the computer.

Intelligent: Plug and play.After power on, the sensor is self-diagnosed and connected, and the parameters are automatically loaded.

High precision: direct digital output, no signal transmission loss, no signal acquisition error, 24-bit A/D converter, the system's conventional accuracy is 0.3%, and the ultra-high accuracy can reach 0.15%.

Networked: General 485 industrial bus, conveniently forming a networked pressure measurement system.

Convenient mode:

Each sensor occupies one USB interface, multiple sensors can be used with USB expanders, and each computer can be connected to 6 sensors.The advantage of this mode is that the sampling rate can reach 1000Hz, and the sampling rate of each sensor can be set independently.

Networking mode: Multiple sensors are attached to a RS485 bus, and only occupy one USB interface.The advantage of this working mode is that the USB port resource occupies less and the monitoring points are many, but the sampling rate decreases with the increase of the number of sensors.The fastest in the networking mode of 128 sensors

Sensor system acquisition software is suitable for Windows XP SP2,

Windows 7/10 operating system takes up less system resources and is simple to operate.It integrates real-time display sensor measurement waveforms, data storage, waveform data playback, data analysis and other functions.The data file supports TXT text format and EXCELL2003 format file output.
