Basically, ultrasonic refers to the acoustic frequencies more than twenty thousand hertz, which are beyond human ear to comprehend. There are various animals such as dolphins, mice, dogs and bats that have the ability of comprehending these sounds because of higher hearing range. Based on pulse velocity, ultrasonic sensors are currently being used in a number of fields for detecting cracks, intrusions and measuring of different levels of liquid, such as ultrasonic level indicator. Ultrasonic liquid level indicators are widely being used in different industries. Ultrasonic fluid and gas sensors are considered as the most accurate ones and most easy to handle ones as well.

Water level and flow indicators have become very important in the water industry. These little devices come in very handy in keeping various devices working in a proper condition. The ultrasonic indicators are currently being used in marines to check water level at various places and in various equipments. There are a number of reasons why ultrasonic meters are preferred over other technologies, especially when it comes to the measurement of fluids inside containers with thick walls. Ultrasonic waves have the quality to penetrate through walls of thickness of 2 15 mm. The waves can penetrate through wall of 15 55 mm too, majorly depending on the material of the tank. By measuring the hollow space within a container, these ultrasonic waves give audio and visual signals back which are shown on the screen of the device.

is very easy to use as well. There are various labeled buttons attached to it that are used to operate the device. To locate the water level within a container, the device s sensor applicator is placed on the expected place, it is rolled over the surface until the lights extinguish, which do when the exact surface of water is located. Ultrasonic technology is being preferred specially in the field where correct measurement is essential and incorrect results can be fatal. Apart from that, the ultrasonic devices are easy to carry, come with accessories and a carrier. They are handy and easy to be taken on a journey with a battery time of about ten working hours.

If comparison is made between ultrasonic and other technologies, there are a number advantages and disadvantages that you come across. Another latest technology that can come near ultrasonic is piezo-resonant sensor. Piezo-Resonant sensors are accurate, reliable, non invasive and economical as well. They are relatively new in the market and have the ability of measuring liquid level within plastic containers and bottles. However, they can only be used for plastic containers and are powered. They also have temperature limitations while ultrasonic sensors can even be used in high temperatures. Capacitive sensors are also famous and quite accurate. However, they require resistive liquids and continuous calibration. Although ultrasonic technology is a little expensive, the devices are light weighed and handy. They are quick in bringing out the results and do not require a large amount of time, besides there is no chance of any kind of damage to the container while measuring through ultrasonic indicators.
