ODM / OEM Range Ratio R250 / R400 / R500 Ultrasonic Water Meter
Battery Life Exceed 10 Years
Ultrasonic water meter is a new type of water meter which can
detect the time difference caused by the change of speed when
ultrasonic beam propagates in the water downstream and upstream,
and then analyze and deal with the flow rate of water so as to
further calculate the discharge of water.
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.
KUHM2100 is an advanced, high-precision ultrasonic water meter with
no moving parts, and KUMH2100 is primarily used to measure
residential tap water consumption.
The Cube ultrasonic water measurement is based on the transit time
method, and all measurements, references, readings, calculations
and data communication is controlled by an advanced specially
designed electronics circuit.
The Cube has no moving parts, presents an IP68 register, and with
big and full information LCD, easy to read the data and see the
