Lorawan 433 / 868Mhz / GPRS Wireless Ultrasonic Water Meter Or Mbus
Output Water Meter For Residence
Description
The Cube is an advanced and highly accurate ultrasonic water meter
designed specifically for residential applications. Utilizing
state-of-the-art technology, the Cube stands out for its
exceptional precision in measuring cold water consumption. One of
its most significant advantages is the absence of any moving parts,
which not only enhances its reliability but also reduces
maintenance needs.
The Cube's ultrasonic water measurement operates on the transit
time method, a sophisticated technique that ensures accurate
readings. This method involves sending ultrasonic signals through
the water and measuring the time it takes for the signals to travel
between two transducers. The advanced electronics circuit specially
designed for the Cube controls all aspects of this process,
including measurements, references, readings, calculations, and
data communication. This high level of integration guarantees that
the data collected is precise and reliable.
Engineered for durability, the Cube features an IP68-rated
register, which means it is fully protected against dust and can
withstand continuous immersion in water. This makes it ideal for
use in various residential environments, even those prone to
flooding or heavy moisture.
The Cube also boasts a large, full-information LCD screen,
providing users with an easy-to-read display of data and alarms.
This clear and comprehensive display ensures that homeowners can
effortlessly monitor their water consumption and respond promptly
to any alerts, thus promoting efficient water usage and early
detection of potential issues.
Overall, the Cube ultrasonic water meter represents a cutting-edge
solution for residential water measurement, combining advanced
technology, robustness, and user-friendly features to deliver
outstanding performance and reliability.
