The difference between guideway meter and ammeter is mainly reflected in three aspects: installation mode, functional positioning and application scenario: guideway meter is an industrial multifunctional power monitoring equipment, which is installed by DIN guideway and supports complex parameter measurement and remote communication; 

Ordinary electric meters are mainly based on basic electric energy measurement, and most of them are wall-mounted and suitable for scattered scenes such as houses. 

Definition and core functions Guide rail meter: The full name is DIN-rail Mounted, which is an industrial power monitoring equipment installed with DIN 35mm standard guide rail.

It can measure complex parameters such as voltage, current, reactive power and power factor, and some models support harmonic analysis and remote data communication. twelve Ordinary electric meter: it is mainly used for the basic measurement of electric energy consumption, with active power measurement as its core function. 

It is commonly used in residential houses and small shops, and its accuracy level is generally 1.0 or 2.0.
