Smart gas meter can save your facility … if you know how it works

Smart meters can do much more than provide a stream of measurements. But here is a catch: operators must know how they work. Here is a story to illustrate. Client installed a smart gas meter for a commercial kitchen. One year later gas supply is blocked. Meter blocked gas supply, it must be at [...]
