Introduction to Aquatrak Company:

Aquatrak provides high-precision tidal level measurement systems suitable for hydrographic, hydrological, and other industrial measurements. In the field of long-term accurate measurement of tidal levels and sea conditions, Aquatrak's products have always been at the forefront of the world and are widely used worldwide. Other applications include boundary measurement, water supply and drainage measurement, and maintenance and protection of dam and water tanks. Aquatrak products use patented ratio time calibration, sound speed/pressure continuous pulse technology, and can be installed with only a small diameter stainless steel tube, with unparalleled performance among similar products.

key word:

The 5000 Aquatrak acoustic tide gauge station is commonly used for measuring sea level and tide level, river water level, groundwater level, and tank level. It consists of six parts: acoustic transducer, data processing box, data receiving and remote reporting box, solar power supply system, data receiving hub, and data receiving and processing software. Automatically calculate the effects of temperature, pressure, and atmospheric density during measurement, with an accuracy of 3mm. Using acoustic technology, the instrument has no mechanical moving parts and does not need to be submerged in water. The sensor is controlled by a microprocessor, with RS-232 and SDI-12 interfaces, suitable for long-term tide level monitoring in unmanned monitoring stations

5000 type acoustic tide gauge station product introduction:

The 5000 type Aquatrak acoustic tide gauge station provided by Qingdao's territorial waters mainly consists of six parts, including acoustic transducers, data processing boxes, data receiving and remote reporting boxes, solar power supply systems, data receiving hubs, and data receiving and processing software. The acoustic transducer and data processing box are manufactured by Aquatrak in the United States, using patented technology to provide reliable and accurate tide (water level) data. Each measurement takes into account the effects of temperature, pressure, and atmospheric density, with an accuracy of up to 3mm. Due to the use of acoustic technology, the instrument has no mechanical moving parts and does not need to be submerged in water. The sensor is controlled by a microprocessor and has two interfaces, RS-232 and SDI-12. It can be connected to most data collectors, computers, control terminals, and modems, making it particularly suitable for long-term tide level monitoring in unmanned monitoring stations. The instrument can set sampling intervals, average quantities, etc. on site. The instrument is equipped with the US NOS Standard Averaging Alorithm from the National Oceanic and Atmospheric Administration of the United States, which can calculate the standard deviation of each set of tidal data for later data processing to calculate the average wave height.

Product advantages:

1. Economical and cost-effective, without the need for high well construction costs; And the maintenance cost is low for many years

2. Mature acoustic tide measurement technology: standard equipment from The U.S. National Ocean Services (NOS) and the Australian National Tidal Centre;

3. High precision year-round monitoring of tide level (water level), with an accuracy of up to 3mm; Also provides average wave height data to estimate sea conditions;

4. No influence of atmospheric pressure changes, resolution 1mm; Zero drift!

5. Intelligent tide level station, unmanned, automatically records and sends real-time data (RS-232 and SDI-12);

6. No contact with seawater, no biological attachment, no instrument loss, no maintenance required, low operating costs!

7. Not affected by waves; Widely used in oceans, lakes, rivers, ports, etc;

8. Low power consumption: only 9 milliamps!

9. Long lifespan: Continuous high-quality operation for over 1 million hours!

10. Global sales exceed 2000 units!
