The most important thing: Choosing the right energy meter
Our experience and recommendations may help you with your decision. From our support in creating metering concepts, our installation activities and the good exchange with numerous customers from different industries, we can make the following recommendation:
Tip 1: Avoid analog electricity meters.
Tip 2: Choose multifunctional meters with a communication interface (e.g. Modbus TCP) if you want to be future-proof. These generally offer the cheapest and most comprehensive solution. All relevant data is recorded and instantaneous values can be read out. The systems are equipped with extensive interfaces and therefore offer great compatibility with other data acquisition systems. You are on the safe side in 95% of cases.
Tip 3: Power quality analyzers, on the other hand, are quite expensive and simply not necessary in most cases. They are only used where sensitive devices are connected that are allergic to flicker (short-term voltage fluctuations), for example, or where harmonics of high harmonics need to be recorded.
Tip 4: Make sure that the meter supports a standardized communication protocol and is not proprietary, i.e. not compatible with other manufacturers. We recommend Modbus TCP, as this makes it much easier to introduce an energy management system.
