Ultrasonic Water Meter DN15-DN40
It is an electronic water meter that adopts the ultrasonic time difference principle to calculate the water flow.
It is an electronic water meter that adopts the ultrasonic time difference principle to calculate the water flow. It has the advantages of high accuracy, high reliability, wide range ratio, good durability and compact size, etc. It can be widely used in the water measurement of residential users.
Accurate measurement: range ratio R400; as low as 1L/h startup flow and drip measurement
Ultra-low power consumption: <10μA metering power consumption @8Hz sampling frequency
Ultra-long life: IP68 protection class, reliable use for more than 10 years
Reliable communication: self-organizing network routing algorithm with core independent intellectual property rights, professional antenna design realizes the wireless communication
a. Communication mode: optional NB-IoT, LoRa, M-BUS; infrared as the second communication interface
b. Data upload function: data uploading at regular intervals: settable between days, weeks, months and specified dates
c. Historical data storage: support daily and monthly usage data storage at the same time
d. Alarm function: insufficient balance, low battery power, drip alarm and other kinds of anomaly alarms
e. Remote upgrade: with wireless, infrared remote upgrade function
f. Valve control: remote valve control function (DN15-DN25 optional)
g. Billing function: support remote top-up and payment, tiered pricing
