Ultrasonic water depth and temperature meter

Portable multifunctional ultrasonic water depth and temperature meterWorking Principle:

Portable multifunctional ultrasonic water depth and temperature meterThe speed of sound waves in air is 340 meters per second, approximately 1500 meters per second in water. It takes exactly 1 second for sound waves to travel back and forth 750 meters underwater, and the round-trip time for measuring sound waves is

It can calculate the depth of underwater targets. (Figure 1) Ultrasonic waves are sound waves with frequencies higher than human hearing, suitable for underwater detection. The depth gauge emits and receives ultrasonic waves through an ultrasonic transducer, and displays underwater targets on a LCD screen by recording and calculating the depth of the water bottom for display.

display instructions

Measuring water depth: the distance from the sensor to the underwater reflection surface;

blind Zone: Usually, sensors cannot be measured in blind spots, while depth sounders have normal blind spots0.2-0.5Between meters, the blind spot cannot be measured;

deep Degree: can be manually set or automatically temperature compensated for correction;

Wen Degree: The water depth sensor is equipped with a built-in temperature sensor, which measures the surface temperature of the sensor

BDSInformation: Coordinates--Economic module, with relatively rough positioning accuracy

altitude--Economic module with relatively coarse positioning accuracyomit

speed--Host device movement speed per second

Date and time: Built in clock chip or,BeidouBDSTime correction

electricity Pool: Usually standby14Hour, measured frequency,BDSUse signal influence.

Portable multifunctional ultrasonic depth and temperature measuring instrumentPrecautions for Host Installation

1. The instrument should avoid direct sunlight and be protected from impact and vibration

2. The sensor must be securely fixed, away from the ship's side, and used for static measurement

3. Avoid blind spot range measurement

4. Use compliant chargers to charge devices

5. The sensor cable is not load-bearing and needs to be measured by holding the connecting rod to avoid cable breakage

6. Instruments should be kept away from equipment that generates electromagnetic radiation, such as motors and generators

7. BDS usage should be as spacious as possibleZone use
