Maddalena Water Meter Pulse Sensor

Short Description:

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

The HAC-WR-M pulse reader is an energy-efficient device that combines metering acquisition and communication transmission. It is compatible with Maddalena and Sensus dry single-flow meters equipped with standard mounts and induction coils. This device can detect and report abnormal conditions such as counterflow, water leakage, and low battery voltage to the management platform. It boasts low system costs, easy network maintenance, high reliability, and excellent scalability.

Communication Options:

You can choose between NB-IoT or LoRaWAN communication methods.

Data reporting:

There 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.

Metering:Support single hall metering mode

Power-down storage:Support power-down storage function,there is no need to re-initialize the measurement value after power-off.

Disassembly alarm:

When 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.

Monthly and yearly frozen data storage

It 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

Parameters setting:

Support 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.

Firmware Upgrade:

Support infrared upgrading
