Technical field
This utility model relates to fluid flow control field, is specifically related to a kind of strongly corrosion liquid flow control system.
Background technology
So-called flow refers to: by the material quantity in a certain cross section in the unit interval, i.e. instantaneous delivery is raw at modern industry
During product, flow is one of important procedure parameter, is efficiency and the important indicator of economy of weighing device, is production exercise
Work and the foundation controlled, because in most industry produces, conventional measurement and control flow determine proportioning and the consumption of material
Amount, it is achieved Automation of Manufacturing Process and optimized control;Simultaneously in order to carry out business accounting, it is also necessary to know such as teams and groups' stream
The medium total amount crossed.So, the measurement of flow is the vital task realizing industrial processes with control.
Flow-measuring method and instrument of a great variety, sorting technique is also a lot, up to now, can industrial flow
Instrument kind reaches 60 kinds more than, and the so many reason of kind is that and is much to seek one so far to any fluid, Ren Heliang
The flow instrument that journey, any flow regime and any use condition are all suitable for.This 60 various flow rate instrument, every kind of product has
Its specific suitability, also has its limitation, divides by measuring principle and has mechanics principle, calorifics principle, Principles of Acoustics, electricity
Principle, optical principle, atomic physics principle etc..According to classification method the most popular, widest at present, i.e. it is divided into: positive displacement stream
Flux of vortex street in gauge, differential pressure flowmeter, suspended body flowmeter, turbine flowmeter, electromagnetic flowmeter, fluid oscillating effusion meter
Meter, mass flowmenter and inserting-type flowmeter, probe type flow meter etc..
