LoRaWAN Non-magnetic Inductive Metering Module

Short Description:

HAC-MLWA non-magnetic inductive metering module is a low-power module that integrates non-magnetic measurement, acquisition, communication and data transmission. The module can monitor abnormal states such as magnetic interference and battery undervoltage, and report it to the management platform immediately. App updates are supported. It complies with LORAWAN1.0.2 standard protocol. HAC-MLWA meter-end module and Gateway build a star network, which is convenient for network maintenance, high reliability and strong expansibility.

● The non-magnetic metering sensor comes with a low-power MCU, which collects and processes 3-channel inductance signals and supports forward and reverse metering. The non-magnetic metering sensor supports automatic switching between high-speed sampling and low-speed sampling to achieve the optimal design of power consumption; The max flow rate is 5 cubic meters per hour.

● Non-magnetic inductance supports the disassembly detection flag setting function. When disassembly is detected, the disassembly flag is set, and the abnormal flag is reported when reporting.

● Battery low voltage detection report: when the voltage is lower than 3.2V (Error: 0.1V), set the battery low voltage flag; report this abnormal flag when reporting.

● Magnetic interference detection and reporting: when it is detected that the module is subject to magnetic interference, the magnetic interference flag is set, and the abnormal flag is reported when reporting.

● Built-in memory, internal parameters will not be lost after power off, and can be used normally without setting parameters again after changing the battery.
