Product application


It is widely used for small flow users of large pipelines, such as community master meter, enterprises, schools, hospitals, fire meters, etc., especially for key users' trade settlement, master sub meter comparison, night leak detection and other occasions.

Product features 


·Double channel ultrasonic metering, sampling frequency up to 100 times / second, metering more accurate and reliable.
 
·Without moving parts, it can keep accuracy for a long time and resist cold weather.
 
·High sensitivity and very low initiating flow (DN100 initiating flow is only 15L / h), which can be used for comparison of total sub meter and leak detection at night.
 
·The range ratio Q3 / Q1 can reach 500 times (the actual range ratio can reach 1000 times)
 
·There is almost no blind area in measurement, and the application scope is wider.
 
·The unique "black box" function can store more than 4000 pieces of historical data.
 
·Equipped with rectifier, not affected by flow field disturbance, low requirements for straight pipe section, and stronger installation applicability.
 
·IP68 waterproof grade, can work underwater for a long time.
 
·Three line LCD display (it can display accumulated flow, instantaneous flow, flow direction, alarm prompt, water temperature and other information at the same time)
 
·The display number of accumulated flow reaches 12, and the decimal point can be adjusted according to the demand.
 
·The life expectancy of lithium battery is more than 10 years, and the six-year warranty is free.
 
·The world's most advanced ultrasonic water meter, originally imported from Arad, Israel.

Installation requirements

·Can be installed in any direction
 
·When not installed horizontally, the water outlet end is upward
 
·Measurement with full pipe
 
·The sensitivity grade of flow profile is U0 and d0 (u2d2 is required when there are valves and screens in front of and behind the table)
