1. Periodic water meter data reporting: The water meter can set hourly, daily, and monthly reporting cycles through the NB-IoT platform network<\/p>\n

based on actual usage. The reported data includes cumulative water consumption, battery capacity, meter status, and reporting frequency.<\/p>\n

2. Each table is directly connected to the server, without the need for concentrator and repeater, and the transmission is safe and reliable;<\/p>\n

3. Built-in valve, the system has the function of remote control valve;<\/p>\n

4. Low installation requirements, no wiring for the base meter, no additional equipment required;<\/p>\n

5. The NB module is integrated with the base table, featuring a built-in antenna to minimize installation-related antenna damage.<\/p>\n

6. The circuit adopts ultra-low power consumption design (or zero power consumption technology), high-capacity lithium-ion battery power supply, battery compartment is independently packaged, battery is easy to replace, battery life is 6 years<\/p>\n

The NB-IoT valve-controlled water meter is a smart device developed to meet the operational needs of water supply companies for intelligent<\/p>\n

management. Designed for remote meter reading and control, it supports two-way communication and allows scheduled valve operation. The meter<\/p>\n

remains in low-power mode during normal operation, automatically waking up daily according to preset schedules for data collection before<\/p>\n

returning to energy-efficient standby mode. This innovative solution streamlines water usage monitoring, simplifies remote management processes,<\/p>\n

and significantly enhances operational efficiency while reducing labor, material, and financial costs.<\/p>\n

The NB-IoT valve-controlled water meter complies with the technical requirements of GB\/T 778-2007 ‘Measurement of Water Flow<\/p>\n

in Closed Full Pipes: Drinking Water and Hot Water Meters’ and CJ\/T 224-2012 ‘Electronic Remote Transmission Water Meter’.<\/p>","protected":false},"featured_media":2069,"comment_status":"open","ping_status":"closed","template":"","meta":[],"product_brand":[],"product_cat":[33,54],"product_tag":[],"class_list":{"0":"post-2024","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-smart-water-meter","7":"product_cat-nb-iot-water-meter","9":"first","10":"instock","11":"shipping-taxable","12":"product-type-simple"},"_links":{"self":[{"href":"https:\/\/jrhmeter.com\/fr\/wp-json\/wp\/v2\/product\/2024","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/jrhmeter.com\/fr\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/jrhmeter.com\/fr\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/jrhmeter.com\/fr\/wp-json\/wp\/v2\/comments?post=2024"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/jrhmeter.com\/fr\/wp-json\/wp\/v2\/media\/2069"}],"wp:attachment":[{"href":"https:\/\/jrhmeter.com\/fr\/wp-json\/wp\/v2\/media?parent=2024"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/jrhmeter.com\/fr\/wp-json\/wp\/v2\/product_brand?post=2024"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/jrhmeter.com\/fr\/wp-json\/wp\/v2\/product_cat?post=2024"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/jrhmeter.com\/fr\/wp-json\/wp\/v2\/product_tag?post=2024"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
