IoT valve controlled remote transmission water meter
DN15-25mm
IoT valve-controlled remote transmission water meter can realize prepayment and postpayment methods. Two reporting modes, valve closing and valve opening, solve the problem of not being able to open the valve in real time. Supports NB-1OT, LORA data transmission and supports Hall, magnetic group, non-magnetic and other sampling methods. The base meter is completely separated from the module without any cable connection.
Product features
◆Micro-power consumption design: It is powered by environmentally friendly lithium batteries, which can ensure the normal operation of the water meter for more than 6 years and facilitate battery replacement.
◆Prepayment function: remote prepayment, free water shutoff, renewal and reuse, supports network and mobile WeChat self-service Payment
◆Supports multiple payment methods: prepayment or postpayment
◆Meter reading and monitoring function: real-time viewing of water use process, statistics, query (hour, day, month, year) and analysis of water use information through the network
◆Check Testing function: can realize various functions such as battery undervoltage, abnormal measurement, valve status, etc.
◆ Sewage and anti-rust function: the water meter switches the valve on and off regularly (monthly) to avoid valve scaling, rust, etc.
◆ Multiple reporting modes: Different valve turning states and different data reporting modes ensure that customers can switch valves on and off in a timely manner
◆Multiple communication methods: The electronic part can support NB-1OT (with ≥7 years of tariff) or LORA, 4G communication transmission mode
