Introduction
Do you live near the sea or a lake? Are you a boat owner and concerned about the water level in your harbor or parking area? Are you curious about the measurements of the water level in your swimming pool to confirm if it is safe to swim?
Then this is the article for you to read. We are talking about a type of instrument that is useful in measuring the water level – the Water Level Meter. This little piece of technology will let you know the exact level of water in any desired area. This instrument is also applicable in a range of areas such as rivers, lake, oceans, leak detection, engineering, hydrology and many more. Be it for a commercial, recreational or scientific purpose, these meters are your one-stop solution.
What is a Water Level Meter?
A Water Level Meter is an electronic device which is used in the measurements of the surface level, tide level and pressure of water. They come in different shapes and sizes, can be fixed, portable or you can configure it according to your needs.
This instrument is designed in such a way that it is quite clutter free, and can even be placed in an open space and devoid of any mud and debris. It has an inbuilt protective casing that provides a waterproof seal which protects the instrument from corrosive and humid environment.
Technology Used in Water Level Meters
The mechanism behind any Water Level Meter is the same, they all use the same type of technology to measure water levels. They all use the same principle to measure the level by which a capillary tube (also known as float) is placed in a medium (i.e. water). The Float is the end-point from which the measurement is taken.
The difference between various types of water level meters is usually in their components and the way they read the data. The most common types of Water Level Meter include ultrasonic level meters, pressure level meters, thermocouple level meters, and radar level meters.
Ultrasonic Level Meters
Ultrasonic water level meters are a type of level meter which measures water level using ultrasonic waves. They are used in a variety of applications such as in rivers, lakes and oceans. Ultrasonic meters use sound waves to measure the level of the surface by sending a sound pulse and receive the results back. The resulting reading is then displayed digitally in terms of depth, level or pressure. Ultrasonic level meters are widely used because of their ease of use, accuracy and functionality.
Pressure Level Meter
Pressure level meters measure the pressure of the water column in order to obtain the water level in the desired area. This type of meter is commonly used in rivers, lakes and seas, either for recreational use or for research. They are relatively inexpensive and often are used in combination with an ultrasonic level meter. Pressure level meters usually measure with a resolution of 0.001 inch per foot.
Thermocouple Level Meters
Thermocouple level meters are particularly suited for conducting measurements in extremely deep or shallow areas, making them very useful in oceanography and hydrology. It uses a thermocouple to measure the temperature of water along with a pressure gage to sense water pressure. Thermocouple level meters measure the amount of change in temperature within the water over a given depth and are used in depths up to several hundred meters.
Radar Level Meters
Radar level meters are used primarily in special effort engineering applications like a coastal oceanography. This type of meter operates by sending out a radar beam, which detects the water level in the reference medium. The resulting reading is then sent to the display enabling the measurement to be read digitally.
Conclusion
As you can see, water level meters are a very helpful device for anyone interested in measuring the water level in an area. They are easy to use, accurate and have a range of applications in areas such as engineering, hydrology, research and recreation. They come in various shapes and sizes, so you should be able to find the one that is right for your needs.
