Features of R400 Ultrasonic Water Meter
It can meet the regional metering requirements of the urban water supply network and is suitable for various industrial sites.
Using low voltage, multi-pulse technology, multi-channel design, and high measurement accuracy, suitable for complex flow state measurement.
Adopt the principle of ultrasonic propagation velocity difference method, no mechanical rotating parts, small pressure loss, and stable and reliable operation.
Anti-interference design, the inverter environment works normally.
Low initial flow rate, high accuracy level, double volume measurement.
Micro power consumption design, the built-in lithium battery can work continuously for more than 6 years without an external power supply.
It can measure flow, temperature, and pressure at the same time, and monitor the operation status of instruments and pipe networks.
Communicate with the platform through the NB-IOT narrowband Internet of Things to realize the functions of regular data reporting and abnormal alarm.
