Ultrasonic water meter is the latest innovation available in the market. These meters were specially designed for domestic water metering applications where conventional water meters fail due to harsh environment, solids in water, high maintenance, magnetic vandalization or incapability of leak detection. An electromagnetic water meter is a volumetric flow meter that does not have any moving parts and is ideal for wastewater applications or any other liquid which is conductive or water-based. Magnetic water meters, in general, do not work with hydrocarbons, distilled water, and many non-aqueous solutions. They are also ideal for applications where low-pressure drop and low maintenance are required.
For years, the mechanical water meter has been a natural choice, but in today’s digital world, with the need for communication and connectivity is increasing each day, good is no longer good enough. Smart metering is the future and it has various advantages in it.
Contrary to its mechanical pendant, the electromagnetic meter has no moving parts which means that it is unaffected by wear and tear and maintains pinpoint precision throughout its entire lifetime. Apart from ensuring correct billing, this also enhances data quality.
In contrast to the mechanical meter, the ultrasonic meter also holds remote reading capabilities without the use of any add-on devices. This not just contributes to a significant decrease in data collection time but also improves resource distribution as misreading and follow-ups are avoided, time and money can be saved for more value-adding activities and helps to obtain a broader spectrum of data from which customers can be served better.
And also the intelligent alarms in the ultrasonic meter enables efficient detection of leaks, bursts, reverse flows, etc. And thereby lower the amount of Non-Revenue Water in the distribution network and prevents revenue loss.
A conventional ultrasonic water meter comprises a sensor and an electronic console. The sensor has two ultrasonic transducers built into its body. Each transducer functions both as an ultrasonic transmitter and receiver, the electronic console operate the two transducers by alternately transmitting and receiving a burst of sound energy and measuring the transit time it takes for sound to travel between the two transducers. The difference in the transit time measured is directly and exactly related to the velocity of the water in the pipe. The flowrate is calculated from the measured velocity and the pipe inner diameter.
