ODM / OEM Range Ratio R250 / R400 / R500 Ultrasonic Water Meter
Battery Life Exceed 10 Years
Description
The ultrasonic water meter represents an innovative category of
water meters designed to assess changes in speed by detecting the
time difference as ultrasonic beams propagate both downstream and
upstream in water. Subsequently, the device analyzes and processes
the flow rate of water, enabling precise calculations of water
discharge. This technology offers a more advanced and accurate
method for measuring water consumption compared to traditional
water meters.
The KUHM2100 is an advanced and highly precise ultrasonic water
meter designed for residential tap water consumption measurement.
Distinguished by its absence of moving parts, this meter utilizes
the transit time method for ultrasonic water measurement. The
entirety of the measurement process, including references,
readings, calculations, and data communication, is overseen by a
sophisticated, specially designed electronic circuit.
Noteworthy features of the Cube ultrasonic water meter include its
lack of moving components, an IP68-rated register for enhanced
durability, and a large and informative LCD display. The display
makes it easy to read data and promptly identify any alarms or
notifications. Overall, the KUHM2100 represents a cutting-edge
solution for accurate and efficient residential water consumption
measurement.
Features
Low initial flow rate, wide range ratio, high measuring accuracy
and stable operation.
Internal no moving parts open flow element, not affected by
impurities in water, long service life. The output communication
function is complete, Meeting all kinds of communication and
wireless networking requirements.
With excellent small flow detection ability, it can solve many
problems of traditional water meters. It is more suitable for
gradient water charge, More suitable for saving and rational utilization of water
resources, and has a broad market and use prospect.
