Made of high-quality materials, copper shell, iron shell or stainless steel body shell is optional. Available with cold or hot water. The water meter is installed vertically. Precision readings can be made to tens of liters. High accuracy (R160). Read the meter regularly. High protection level: IP68. The meter has no built-in battery and can be read immediately after being powered on. Ultra-low power consumption design. Communication method M-BUS or RS485 is optional. High resistance to light interference. Proactively report sensor fault information and battery status information.

Installation Requirements
●The water meter must be vertically installed,with the reading surface upwards and the direction of the arrow being the same as the direction of the water flow.
●The pipeline must be flushed before installing the water meter.
●The water meter must be installed in a dry and easy to maintain environment,install in a dedicated water meter box is recommended.
●Valves must be installed at the inlet and outlet of the water meter.
