Instrument Overview
It can be widely used for measuring flow velocity and water temperature in various settings, including oceans, rivers, open channels, coastal observation stations, ships, and buoys. It can also be employed for fixed, unattended, automated online measurements.
Product Features
Combines flow rate and water temperature parameters; features automatic calibration at low flow rates, and is equipped with lead weights for use at high flow rates; incorporates anti-corrosion nanotechnology; measures water level via pressure; supports multiple communication interfaces.
Technical Parameters
| Flow rate frequency | 5MHz |
| Flow rate range | 0.02–7.00 m/s |
| Flow rate accuracy | 1.0% ± 1 cm/s |
| Flow rate resolution | 1mm/s |
| Water temperature range | -5℃ to 40℃ |
| Water temperature accuracy | ±0.5℃ |
| Water temperature resolution | 0.01℃ |
| Depth of immersion | 50-meter water area (customized for other ranges) |
| Measurement mode | Automatic and manual two types |
| Measurement interval | Automatic mode: Select a value from 0 to 120 minutes, with a minimum increment or decrement interval of 5 minutes. Manual mode: Measurements can be taken once or multiple times in succession, with any desired interval. |
| Speed measurement duration | Automatic modes: two options—60 seconds and 100 seconds. Manual mode: 10–120 seconds, with incremental or decremental selection. |
| Working power | External DC 12V power supply |
| Output interface | RS232 by default, other customizations available |
| Protection level | Probe IP68, handheld or wall-mounted host IP65 |
| Water flow direction identification | The flow velocity probe automatically identifies the direction of water flow and can rotate freely within an azimuth range of 0–360 degrees. When the flow velocity exceeds 0.5 m/s (or 1 m/s), a lead fish device can be suspended from it. |
