Product details
1 summary:
NB-IOTThe IoT ultrasonic water meter is a new type of electronic water meter based on the principle of ultrasonic time difference for flow measurement, used to measure the instantaneous flow rate and cumulative total amount of water flowing through the tap water pipeline. The water meter has remote transmission function, and data can be remotely read through the system platform.
II Product features:
lWide range of measurement, up to a maximum ofR400.
lThere are no moving parts in the table, which works reliably and is suitable for measurement under complex conditions.
lIt has multiple alarm functions such as flow sensor failure, flow over range, and undervoltage alarm.
lMicro power design, powered by one lithium battery to ensure usage6Years or more.
lEquipped with optoelectronic interfacesM-BUS、RS-485Multiple communication interfaces such as wireless.
lData Storage: Automatically Save Recent Data24Monthly historical record data, safe and reliable.
