Product description
UItrasonic water meter is a kind of Intelligent integrated large caliber water meter,which can detecte very low initial momentum with ultrasonic technology,and equipped with built-in stainless steel strainer, its very low initial momentum can save a lot of extra money for users.
Working Principle
Double Channels can be thought of as two lanes,A and B swim in opposite directions from each lane. Suppose the current has directions,A floats down the lane,B against the current.The time difference from A and B touch the wall is proportional to the speed of the water,we can recieve an exact average flow velocity through repeated swimming, if multiply accurate flow velocity by invariable cross-sectional area then you will get accurate flow value.
Features
Double Channels sing around method,measure more accurate.
Very low initial momentum reaches 25L.
Actual measurement range over 500.
Protection grade IP68.
Adopt battery: battery lifetime is more than 10 years.
No front and back pipes require U0/D0.
Function of alarm and statistics.
LCD display:flow direction,instantaneous flow,accumulated consumption,different units etc.
Reserved automatic meter reading and network monitoring interfaces.
Free to set forward and reverse current pulse or 4-20mA Instantaneous output.
