SMITH8013-A2 Smith wall hung flow computer is a kind of intelligent industrial control instrument. It adopts The bus  Not-foreign the single-chip microcomputer system design methods,with enough system internal channels and data storage area (take off electrical protection), convenient to expansion structure and function it can make up  second measurement/control instrument  with different types and different purposes flexibly  (such as screen pack, lie between blasting, relay control, current ring, etc.). This series of instrument has these characteristics :simple structure, high reliability, the function is all ready, type variety, especially suitable for supporting flowmeter, the flow measurement of the quality or volume; And through the panel into parameters, automatic control valves open and close  and achieve  the realization of automatic control issue homework. Visualization Chinese interface display, make the person be clear at a glance.
She has Smith8013C single road
Smith8013A2-Ⅱ double road control
Smith8013A2-Ⅲ three road control
Smith8013A2-Ⅳ four ways of control and other forms;
