Gossen Metrawatt expands its portfolio of MID-certified ENERGYMID energy meters, adding models with a radio interface based on the LoRaWAN standard. The radio protocol features a long range and bidirectional communication, using secure AES encryption. The new ENERGYMID LPWAN energy meters are powered from the measuring voltage; users do not need to exchange batteries. Radio transmission creates significant cost savings as it requires no communication channels or time-consuming cabling. This enables easy integration into IoT structures and makes ENERGYMID LPWAN energy meters a perfect fit for decentralized, billable energy data acquisition at locations without wired communication, mobile meter stations such as construction site power supplies or small distribution boards and for integration into existing LoRaWAN networks. The new generation with radio function comes in several types, including versions for 4-wire networks, 400 V with 5(80) A direct connection or 1/5(6) A transformer connection.
The devices record up to 33 measured variables in addition to the active power, such as reactive and apparent power, neutral conductor current, power factor, frequency, as well as power fed to the grid. They also monitor the network quality via THD current and voltage measurements. Like all ENERGYMID meters, the new series is highly compact, measuring only four standard width units, and can be mounted on 35-mm DIN top-hat rails in any position. Their high-contrast three-line LCD display with LED background illumination ensures excellent readability of measurement values. It simplifies connection parameter monitoring and warns of installation errors by changing colors. The devices are tamper-proof, featuring configuration disabling and sealed covers.
