Digital wave height meter is an instrument based on modern sensing and data processing technology, which is used to accurately measure the wave height and related parameters of the water bodyocean, lake, reservoir, laboratory tank, etc.).

1. Digital Wave Height Meter Product Introduction

The digital wave height meter is equipped with a low-power microprocessor, a 24-bit high-precision AD converter, and long-distance communication technology. It is equipped with a capacitive wave height sensor, which has good linearity, low power consumption, high quantitative accuracy, long transmission distance, stable performance, and strong anti-interference ability. The sensor adopts a one-piece structure, which is simple and convenient to install. USB interface, directly powered from the USB port, no need for external power supply, and data acquisition equipment, flexible and convenient installation. It is mainly used to measure the free

Fluid waves, water level height, etc. Can be used in independent working mode (the highest sampling rate is 1000Hz), and can also be used in network mode through RS485, the network mode can collect data from up to 128 measuring points simultaneously. Run the sensor acquisition software, and the wave form data can be displayed, saved on the computer in real time. The computer software displays, monitors and stores the curve of the measuring process, and the data file supports output in TXT format and EXCELL file format.

Second, product features

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

Intelligence: plug and play. After power on, the sensor self-diagnoses, self-joins, and parameters are automatically loaded.

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

Networked: Universal 485 industrial bus, convenient to form a networked pressure measurement system.

Convenience mode:

Each sensor occupies a USB interface, and multiple sensors can be used with a USB hub. 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.

Network mode: multiple sensors are connected to a single RS485 bus, occupying only one USB interface. The advantages of this working mode are low USB port resource occupation, many monitoring points, but the sampling rate decreases as the number of sensors increases. The fastest

Sensor system acquisition software is applicable to Windows XP SP2,

Windows 7/10 operating system, low system resource consumption, simple operation, integrates real-time display of sensor measurement waveforms, data saving, waveform data playback, data analysis and other functions. Data files support TXT text format, EXCELL2003 format file output.
