Ultrasonic Water Meter DN50-DN300
The ultrasonic water meter has the advantages of small size, good stability, low power consumption and strong anti-interference ability;
The ultrasonic water meter has the advantages of small size, good stability, low power consumption and strong anti-interference ability; it also has a small flow detection ability, which is conducive to the rational use and saving of water resources by users. It is suitable for accurate measurement and trade settlement of urban water supply pipeline and household-based master meter flow, and also suitable for DMA zoning measurement management.
Accurate measurement: wide range ratio, low startup flow rate, satisfying the accurate measurement of minimal flows
Ultra-protection: the complete machine is of IP68 protection design, and can work for a long time when being immersed in water
Ultra-long life: micro-power design, reliable use for more than 10 years
Reliable communication: support NB-IoT, RS-485, M-BuS and other transmission modes
Low carbon and environmental protection: environmental protection seamless stainless steel pipe, no casting, no pollution
Multiple functions: it can measure flow and pressure at the same time (optional), which meets the demand of water supply network monitoring
a. Communication mode: NB-IoT, RS-485, M-BUS optional; 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: temperature sensor failure, low battery, empty pipe bubble and other kinds of anomaly alarms
e. Remote upgrade: with wireless, infrared remote upgrade function
f. Billing function: support remote top-up and payment, tiered water pricing
g. Power supply: power supply by DC3.6V lithium battery; DC10V ~ DC36V (proposed when ordering)
