<1> Outline
Smith3014 type Duct Metal Floater Flow meter (also called as the metal rotor flow meter), divided into two series Smith3014H and Smith 3014D.It has the characteristic of simple structure, reliability, a wide range of applications, high accuracy, easy installation, and other. This series of flow meters compared with glass Rotor meter, has characteristics of high pressure, high temperature, strong safety, concise reading. It is applied to opaque media and the corrosive medium flow measurement. Instrumentation and control of the stainless steel flange (1 Cr 18Ni9 or 0 Cr18Ni12Mo2Ti).
Smith3014H Series: conventional type of orifice, floater stainless steel, Preservation of the orifice plate, floater and possession of a Teflon-lined PTEE, the type of scene showed.
Smith3014D Series: Float, conical stainless steel tube, the scene showed 4 ~ 20mA, 1 to 5 V, 4 ~ 20mA + HART, such as remote.
This series of Instrument parameters and the conversion and amend provide standard calculation method by the instrument software to ensure the accuracy of measurement instrument.
<2>Measuring principle
The series of Smith3014 duct metal floater flow meter is metal tube variable area flow meter. The vertical measurement of the flow meter, the fluid flows through the tubes up, the float upward movement in a position floater suffered lift and gravity to balance this When floater and orifice (or cone of) the circulation annulus to maintain a certain area. Annulus area and floater are in proportion to the increase height, a high floater on behalf of the size of flows. Float moved up and down, in the form of a magnetic coupling position will be transmitted to the external indicator, the indicator follow floater mobile. Electric-pointer in directing the flow at the same time, and through the angular displacement sensor and electrical transmission circuit, the flow of accurate conversion into 4 ~ 20mA.
