The echo sounder is essentially a speaker (transmitter) and microphone (receiver) in one single unit. The speaker sends out a pulse of sound, and the time taken (in seconds) for the pulse to return to the microphone is multiplied by 1.5. This gives the distance (in kilometres) to the object the echo sounder was 'aimed' at. The most common use is as a depth sounder for ships.
A device for measuring depth of water by sending pressure waves down from the surface and recording the time until the echo returns from the bottom.
Having a built-in ir transmitter receiver is a fabulous idea
By differential pressure of the liquid and the air gap above the liquid. Both the pressures are given to the differential pressure transmitter, and the signal received from the transmitter is then converted into level using conversion factors supplied by the supplier of the transmitter.
Echo offended the goddess Hera by keeping her in conversation, thus preventing her from spying on one of Zeus' amours. To punish Echo, Hera deprived him of speech, except for the ability to repeat the last words of another.
Ebay was the website that was founded by one Pierre Omidyar in 1995 under the Echo Bay Technology Group. In 2009, Echo Bay Technology Group completed the sale of Skype.
An echo sounder measures water depth by sending a sound wave (ping) from a transmitter down to the seabed. The sound wave reflects off the seabed and returns to the echo sounder, which calculates the time it takes for the signal to return. By knowing the speed of sound in water, the echo sounder can determine the depth of the water based on the time taken for the signal to return.
An echo sounder uses sound waves to determine the depth of water. The time interval between transmission and the return of a sonar pulse is recorded, based on the speed of sound in water. A disadvantage of an echo sounder is that temperature affects the speed of sound in water, so a warm thermal layer can distort readings. An advantage of using an echo sounder is that it is very quick and also very environmentally friendly.
An echo sounder has two major parts: the echo sounder, which includes a display screen, the transceiver to drive the transducer and receive the echo information, and a microcomputer to process the information. The transducer which generates sound waves and receives the echoes of the sound waves is the second major part. The information that is received is fed through cables to the echo sounder, which interprets it and presents it in an understandable manner on the display screen.
An echo sounder operates by measuring the time taken for a sound wave to travel from the device to an object on the seabed and back again. This time measurement is used to calculate the distance between the echo sounder and the object by utilizing the speed of sound in water.
An echo sounder works by sending out sound waves into the water and measuring the time it takes for the sound waves to bounce off an object or the sea floor and return to the device. By calculating the time taken for the sound waves to return, the device can determine the depth of the water or the distance to the objects in the water.
echo sounder is an instrument that function on the principal of sound (echo). an echo sounder is consists of four main parts ,transmitter.transducer.receiver.recorder.the function of the transmitter is to produce energy in the form of pulses of electrical oscillations. in transducer, the e; electrical energy is converted to sound in the water and conversely, the sound waves of the returning echoes are converted back to the electrical energy. the function of the receiver is to amplify the weak electrical oscillations produced in the transducer by the echo so that they can be recorded or displayed . the echo's can be displayed on a paper or recoded ( in the form of graph or digital data)Z.A.BHUTTABS MARINE SCIENCE (LUAWMS)MAS MARINE SCIENCE (KU)PAKISTAN

Is an instrument used to determine the depth of water by measuring the time interval between the emission of a sound signal and the return of its echo from the bottom.
An altitude sensor provides altitude data to within 30-centimeters. An echo sounder is a device for determining the depth of the seabed or detecting objects in water by measuring the time taken for sound echoes to return to the listener.
The echo sounder, a device used for measuring the depth of water by emitting sound waves and timing their return, was first discovered in the early 20th century. The exact year of discovery can be attributed to various inventors and researchers who contributed to the development of this technology.
