The water meter adopts the detachable screw wing dry metering structure, the impeller and counter are driven by magnetism, the combination of the word wheel and the pointer is displayed, with the features of convenient reading, long-term clear, anti freezing, high metering accuracy, remote meter reading, beautiful appearance, safety and health, long service life, etc. Meter and acquisition equipment are connected by M-BUS or RS485 bus, remote and intelligent reading of water consumption data of user's water meter, realizing network connection and data sharing with settlement center.
Product use
It is used to measure the total volume of water flowing through the tap water pipeline and determine the reading through photoelectric positioning. It can also be connected with the acquisition equipment by M-BUS or RS-485 bus to read and transmit data to switch the valve. It is suitable for small industrial water and domestic water metering.
Product features
A. reliable measurement: no error code, no electromagnetic interference, inorganic electric cumulative error; wet water meter, high measurement accuracy, full seal design, good waterproof performance, direct reading water meter can work underwater.
B. passive direct reading: there is no battery inside the water meter, and the meter reading is powered by the bus at the moment. No electricity is needed for daily measurement, and only when reading, the power is supplied, saving energy and avoiding a lot of maintenance work caused by battery power supply problems.
The C meter has a unique address and can be set as needed.
D simple installation: the meter has built-in electronic D code, automatic addressing, automatic registration, without initialization; M-BUS bus communication interface, long communication distance, two core wires without pole connection, low construction cost, simple networking.
E the intelligent module does not participate in the measurement and will not affect the measurement accuracy, which is completely determined by the meter itself.
F. convenient maintenance: long service life, automatic report of water meter status, timely location of failure points; GPRS wireless remote transmission form can achieve real-time comparison of total and sub meters, reduce leakage; meter reading, reduce nuisance.
G fair trade: meter reading system can charge according to the step price and adjust the charge price at any time; valve control direct reading can realize prepayment, the valve is a ball valve, and it can turn on and off the valve regularly for automatic maintenance.
H is not attacked by external strong magnetic field, and its anti-interference performance is very high.
