Ultrasonic water meter is a new type of
water flow meter, by detecting the ultrasonic beam propagation in the water and
tide by speed changes generated, which analyze and process water flow rate. Ultrasonic
water meter is the use of ultrasonic time difference principle, the use of industrial
grade.
Ultrasonic Water Meters have the following features:
low initial flow rate, wider measuring range, higher measuring accuracy, good stability
and no need to set parameters installed at any angle. No moving parts inside
the unimpeded flow element, is not affected by impurities in the water, and
long service life.
The
ultrasonic Water Meters have excellent low flow detection capabilities, which
can solve the problem of many traditional water meters, more suitable for water
gradient charge, more for conservation and rational use of water resources and have
broad market prospects and use,is a good product to as Home Water Meter.

In the R&D process, 3nh scientists and engineers measured various color samples from dark to light, white to black, and other standard color boards provided by ISO (International Standardization Organization). The parameters of test results are integrating with international standards.
Â
3nh also analyzed the parameters from Japan, American and Germany spectrophotometers. The differences of L*ab absolute value between them are within ±1.5. Compared the L*ab value between NS810 and Japan spectrophotometer, when measuring any color objects, the biggest L*ab difference is within ±1.0. This is a breakthrough of 3nh high technology which realizes to be fully compatible with international market.
