Water Meter Retrofit Module

Make : EnthuTech
Brand: ETS IoT
Model: ETS IoT - WM

Product Overview:

The ETS IoT – WM is a LoRaWAN Water Meter Retrofit Module used to Interface Water Meter with RS485 Modbus Output (or) Pulse Output. It will send the RS485 Modbus supported parameters (or) accumulated pulse count to the server.

ETS IoT - WM runs standard LoRaWAN 1.0.3 in Class A. It can reach a long transfer range and is easy to integrate with any LoRaWAN-compatible gateway and IoT server.

For data uplink, ETS IoT - WM sends user-defined commands to RS485 devices and gets the return from the RS485 devices, and processes these returns data according to user-defined rules to get the final payload and upload to the LoRaWAN server. For Pulse Output User Can gets the accumulated pulse count based on the periodical Interval.

ETS IoT - WM Supports BLE configuration and wireless OTA update which makes users easy to use.

This has multiple power supply options as specified. The above image shown is Solar Power version based on Power supply selection product image may vary.
