<1>.Smith2011 Three Variable Area (also called fixed metal scraper) flow meter is following smith2012 sliding metal scraper flow meter after generation of new products, and she from a shell containing three synchronous rotation of a special rotor, rotor were installed in three different shapes of the rotor indoors, the internal component of the flow meter no inter-metal direct contact with the metal. No contact will be no wear, no wear, the gap will not be increased, space does not increase, the leakage will not increase the leakage rate is not increased accuracy can forever preserve as new. The rotor and the rotor seal for the line sealed its seal of the smallest, thus ensuring the fluid minimize friction with the rotor, it formed with any other listing of the displacement meters are compared to the minimum pressure drop, and leakage to the minimum and achieve in large and medium viscosity at the end of the scope of the flow of time, has good accuracy (such as liquefied petroleum gas, etc.)

<2>.Both the rotor rotating around its own axis, turning the entire process, all the peripheral surface of the rotor angle formed remains unchanged, and each rotating semi-circle, the rotor at different times within the natural formation of 1 ~ 20 mm wide impurities channel (Path small channel dimensions are small). Ensure that the viscosity of the material (such as: wax, glue, ink) and contain fiber, sand (for example: pulp, cement mixing of crude oil, asphalt, animals feed), the smooth dielectric measurements.
<3>.Flow meter rotor songs are from the precision machining, in the flow meter internal reciprocating movement and no swing, smooth rotation has an extremely long service life.

<4>.Accuracy, function and application will other conditions remain unchanged, for flow measurement, with the best accuracy. Its 50:1 within the context of repeatability error does not exceed 0.05%.Accuracy has nothing to do with the fluid viscosity. As Smith III shear rotor flow meter and the smallest surface smooth flow characteristics, Smith low viscosity-type three rotor instrument to accurately measure viscosity <2mPa.s media, standards-based measurable 2 ~200mPa.s medium and high shape under different environmental measurable 200 ~ 350,000mPa.s the media.
<5>.Temperature changes will not affect the accuracy of flow meter. Rotor flow meter that three key components have a common linear expansion coefficient, medium -40°C~+80°C without amendment, to be precise determination. Amended application medium temperature can be as high as 350°C .

<6>.Adapt Media Acid,,alkali, salt, water,oil, various types of liquid medium.

<7>.Special functions and Annex

According to customer demand, product can be built-in automatic system smooth, automatic generation devices, automatic temperature compensation devices. And let provide, filters, pipes stretching connector, and other products.
