1. 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, and is equipped with a capacitive wave height sensor, which has good linearity, low power consumption, high measurement 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 power from 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, which can collect data from up to 128 measuring points simultaneously. Run the sensor acquisition software, and the wave form data can be displayed and 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.

II. Product Features
Digitalization: Digital output, no need for other acquisition devices, connect to a computer to display the wave height time curve.
Intelligence: Plug and play. After power on, the sensor self-diagnoses, self-connects, 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%, and ultra-high accuracy can reach 0.15%.

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

Convenient mode:
Each sensor occupies one USB interface, and multiple sensors can be used with USB extenders. Each computer can connect 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 that the USB port resource occupation is small, the monitoring points are many, but the sampling rate decreases as the number of sensors increases. The fastest
