It is decrescence small, when preposition rectification hole plate and horizontal direction angle once at 22.5 °, 30 °, 45 ° when water in preposition rectification orifice plate
Circulation area is gradually increased), water flow sets rectification orifice plate later and enters tubular tube bank, by restrain water flow is carried out it is last whole
Stream.
In practical applications, the adjustable fairing of liquid is mounted on to the upstream of fluid flowmeter, liquid can be nestled up
Flowmeter installation, can also (distance can determine according to site space size) spaced apart, filled in the adjustable rectification of liquid
It sets the liquid that upstream comes and passes through the thicker conveyance conduit of size, the flow velocity for causing fluid to flow is just smaller and unstable, works as liquid
Body enters inside fairing shell 1, and successively passes through level-one rectifier cell 13, liquid chamber 10, second level rectifier cell 14, herein
In the process, liquid passes through level-one rectifier cell 13, since tubular screens bore is less than shell mouth in level-one rectifier cell 13
Diameter, and only tubular screens can circulate for fluid, and baffle can play the role of stopping fluid, reduce fluid circulation
Area, then flow velocity necessarily increases in the case where the flow of fluid is certain；Liquid travels from liquid room 10 enters second level rectification
Element 14, the flow velocity of liquid becomes higher more stable, so that the detection of flowmeter is more acurrate.
Liquid after the filtering of the adjustable fairing of liquid, speed-raising and rectification, caused by deviation be up to state standards,
When being measured using fluid flowmeter, it is ensured that its measurement accuracy and long-term work.
