<1>Outline
The series of Smith3011 Vortex Flow meter is very accurate instrument and has effective gases、liquids and saturated steam flow measurement. The specifications of Smith3011 can be internal temperature compensation, pressure compensation or direct flow measurement. Each meter can be allowed to carry 4 ~ 20mA、4 ~ 20mA + HART analog output and scene show. The series of Smith3011 vortex flow meter is made up of the test sensors of the long-term practice and shell and application with SSP (signal processing) features digital electronic technology. Even on more poor working conditions, Smith3011 vortex flow meter also has high precision and stability. Therefore, Smith3011 vortex flow meter is better choice to reduce production costs and improve the efficiency of equipment.
<2>Features
Highly accurate - when properly installed and flow measurement accuracy of not more than± 0.75%, better circumstances do not exceed ±0.5%.
Good self-diagnosis function - simplified Street wiring design and signal processing. Each meter is a good user interface and common programming including self-diagnostic ability. It can identify Bi –phase processes and the flow-speed external using parameters by programming, and identify vibration pipeline facilities and such as common problems advanced signal processing – each meter has advanced filtering algorithm. These algorithms allow for the establishment of the real-time instrumentation to identify and prevent the ability of non-normal signal. Such as noise ad so on..

The Numerical of the pressure loss P has something to do with the flow and the media, please Determine in accordance with click formula: First , please users from their own hands parameters found in the medium density, and then from the data for an uncovered pressure loss coefficient C, and then use the formula ( 1 ) in the calculation of the pressure losses: P: P = C ×ρ ( 1 )
(1) the formula: P-pressure loss（mm H2o）C -pressure loss coefficient
