Wave height meter

1. Product introduction of Langgaiyi

The wave height meter is also called a digital wave height meter. The wave height meter uses 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. It has good linearity, low power consumption, and high measurement 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 and takes power directly from the USB port. It does not require an external power supply or data acquisition equipment, making the installation flexible and convenient. Mainly used to measure free fluid waves, water level height, etc. It can be used in independent working mode (the highest sampling rate is 1000Hz), or it can be used through RS485 networking. In the networking mode, up to 128 measuring points can be collected simultaneously. Run the sensor acquisition software to display and save the waveform data in real time on the computer. The computer software displays, monitors and stores the measurement process curves, and the data files support TXT format and EXCELL file format output.

2. Features of Langgaiyi products

Digitization: digital output, no need for other acquisition equipment, the wave height time curve will be displayed when connected to the computer.

Intelligent: plug and play. After powering on, the sensor self-diagnoses, self-connects, and automatically loads parameters.

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

Networking: Universal 485 industrial bus can easily form a networked pressure measurement system.

Convenient mode:

Each sensor occupies a USB interface, and multiple sensors can be used with a USB extender. 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 connected to an RS485 bus, occupying only one USB interface. The advantage of this working mode is that it consumes less USB port resources and has more monitoring points, but the sampling rate decreases as the number of sensors increases. Small, fastest in 128 sensor networking mode

The sensor system acquisition software is suitable for Windows Data files support TXT text format and EXCELL2003 format file output.
