NINGBO DONGHAI GROUP CORPORATION

Model Name：
LXCD-40~300
Ultrasonic water meter

Features：

.Widely range,Range ratio up to 1:500
.Service life of more than 15 years, Maintenance-free
.High degree of protection,Strong anti-interference ability
.Light weight, simple to install, easy to check
.Very low starting flowrate,reduce the measurement blind zone, Reduce the gap between production and sales
.No internal mechanical parts,avoided decrease in metering performance due to durable and stable measurement
.Two channel,time difference method, automatic calculation, extremely accurate
.Measure backflow available,And store or display the amount of backflow water
.Provide more information than mechanical water meter, Such as: water flow direction, instantaneous flow, various alarm information
.Only working status,non verification status

.This product is suitable for the accurate measurement of the total meter flow of industrial water and urban water supply sub house- holds.It solves the problem that the traditional water meter starting flowrate is large,,small flow measurement is not accurate,it also applies to non-powered site
