L54215/L54230 LoRaWAN Enabled Battery Powered Two Channel Pulse Counter Overview
The H2O Degree L54215/L54230 wireless LoRaWAN Enabled Battery Powered Pulse Counter monitors and records dry contact pulses from utility meters to determine energy or water consumption. Model L54215 is a one-channel pulse counter, and model L54230 is a two-channel pulse counter.
State-of-the-art LoRaWAN wireless technology is integrated into the pulse counter to provide best-in-class wireless communication. The wireless system can communicate over a 1,000 foot radius from the gateway within a garden-style apartment complex and up to 30 stories within high-rise properties without any repeaters.
The LoRaWAN network employs an open protocol network compatible with other products on a secure and reliable platform.
The devices aredesigned to support water and gas pulse meters. The pulse counter device uses a battery powered wireless radio (10 year battery life) to report consumption. There is a 32-bit unsigned cumulative pulse counter register for each of the two channels. The pulse counter continues to count pulses even if the radio is unable to transmit the data.
