Maddalena water meter pulse reader

Product Model: HAC-WR-M (NB-IoT/LoRa/LoRaWAN)

  HAC-WR-M Pulse reader is a set of metering acquisition, communication transmission in one of the low-power products, compatible with Maddalena, Sensus all with standard mounts and induction coils dry single-flow meters. It can monitor abnormal conditions such as countercurrent, water leakage, battery undervoltage, etc., and report to the management platform. The system cost is low, easy to maintain the network, high reliability, and strong scalability.

  Choice of solution: You can choose between NB-IoT or LoraWAN communication methods

LoRaWAN Features

No.FeatureFunction Description
1Data reportingThere are two data reporting methods.


Touch to report data: You must touch the touch button twice, long touch (more than 2 seconds) + short touch (less than 2 seconds), and the two actions must be completed within 5 seconds, otherwise the trigger will be invalid.

Timing active data reporting: The timing reporting period and timing reporting time can be set. The value range of the timing reporting period is 600~86400s, and the value range of the timing reporting time is 0~23H. After setting, the reporting time is calculated according to the DeviceEui of the device, the periodic reporting period and the timing reporting time. The default value of the regular reporting period is 28800s, and the default value of the scheduled reporting time is 6H.

2MeteringSupport non-magnetic metering mode
3Power-down storageSupport power-down storage function,there is no need to re-initialize the measurement value after power-off.
4Disassembly alarmWhen the forward rotation measurement is greater than 10 pulses, the anti-disassembly alarm function will be available. When the device is disassembled, the disassembly mark and the historical disassembly mark will display faults at the same time. After the device is installed, the forward rotation measurement is greater than 10 pulses and the communication with the non-magnetic module is normal, the disassembly fault will be cleared.
5Monthly and yearly frozen data storageIt can save 10 years of annual frozen data and monthly frozen data of the last 128 months, and the cloud platform can query historical data
6Parameters settingSupport wireless near and remote parameter settings. The remote parameter setting is realized through the cloud platform. The near parameter setting is realized through the production test tool, i.e. wireless communication and infrared communication.
7Firmware UpgradeSupport infrared upgrading
