Water Depth Gauge for Boat

1.The HS-SFCC Portable Ultrasonic Water Depth Gauge is handheld and portable. There are also hooks on the back to fix it. When in use, screw the sensor connecting rod to the sensor. Then securely connect the connecting rod. The protection requirements of cables should be considered during installation.

It is recommended to pass the cable through the connecting rod of the configuration first. Then screw the connecting rod onto the sensor head. The sensor thread size is 1 inch. In order to avoid the cable being stressed, the cable will be broken and the sensor will be permanently damaged.

2. Ultrasonic water depth sensor can only work in water, not in air. The meter will display “nor”. In order to prevent the influence of water surface waves on the test, it is recommended that the sensor is immersed no less than 0.5m below the water surface.

3. When working in sea water, you need to enter the N value or salinity value in the P1 menu.

4. The ultrasonic sensor and the meter circuit are matched and cannot be interchanged. And the sensor cable cannot be lengthened or shortened by itself.

5.The transmit power cannot be set too large or too small, otherwise it will not work normally.

6. The ultrasonic bathymeter has blind spots. The value displayed within the blind zone is a random value.

7. The ultrasonic bathymetry sensor has a corresponding beam angle. When using it, please note that there must be a sufficiently large reflecting surface, and there must be no obstructions around the beam angle range.

8. Because the sensitivity of this instrument is very high. Therefore, there should not be too strong noise or electromagnetic interference near the instrument during use. If the water flow is large, the temperature and humidity are not within the specified range.
