Smart Metering & Monitoring
Advancing energy IoT with innovative PMDs
Power metering and monitoring devices (PMD)
with great installation flexibility
Electrical monitoring at sub / final distribution system is often limited by the space left at the existing distribution boards to install additional monitoring devices. The solution is to install add-on smart energy sensors directly above or bellow circuit breakers or to used smart circuit breakers/switches integrated with metering and monitoring functions.
In 2022 winter, Bituo Technik launched SPM01/02, an ultra-compact smart energy sensor offering Class 1 accuracy (IEC 61557-12 PMDs). With its compact form factor and extensive wired and wireless communication options, system integrators and installers can effortlessly integrate real-time electrical monitoring capabilities into existing distribution boards. For energy IoT transition, We will bring more innovative PMDs to the market.
Add-on features requiring no Din rail space
The smallest energy monitors/meters perfectly fitting for home and small business
Thanks to its compact size and versatile communication types, SPM01/02 can be installed in both existing and new distribution boards to provide real-time energy monitoring for home energy management systems, building management systems or facility management systems.
