A water meter that adopts the principle of ultrasonic measurement has the function of remote transmission of water volume data. The metrological performance of the product meets the national standards for "Drinking Cold Water Meters" the industry standards for "Electronic Remote Transmission Water Meters" of the Ministry of Construction.
Product features:
Adopting dual channel ultrasonic measurement, with a wide range extremely high sensitivity.
There are no moving parts in the table, which is suitable for measurement under complex conditions.
Timed data remote transmission can be used for tiered water pricing.
Display the direction of water flow, instantaneous flow rate, cumulative water volume.
Built in lithium battery, expected working life of 10 years.
The shell protection level is IP68.
Installation requirements:
Horizontal installation, with the surface facing upwards, the meter always filled with water.
When installing obliquely vertically, the water flow should be low in high out.
Sensitivity level of flow profile: U0D0.
