Description
Technical field
Flow monitoring equipment technical field is the utility model is related to, more particularly to a kind of Li Tuoba flowmeter structures.
Background technology
Li Tuoba flowmeters are a kind of differential pressure type, speed average formula flow sensor, when fluid flows through probe, before it
Portion produces a high pressure distributed area, and the pressure in high pressure distributed area is slightly above the static pressure of pipeline.According to Bernoulli equation principle, fluid
Speed is accelerated when flowing through probe, produces a low pressure distributed area at probe rear portion, the pressure in low pressure distributed area is slightly below pipeline
Static pressure.Fluid at probe rear portion produces partial vacuum after being flowed through from probe, and vortex occurs in the both sides of probe.Uniform speed flow is visited
The cross sectional shape of head, the position of rough surface situation and low pressure pressure port are the key factors for determining probe performance.Low-voltage signal
Stabilization and accurately to average rate probe precision and performance play a decisive role.Li Tuoba uniform speed flows probe can accurately detect
To average differential pressure caused by the average speed as fluid.Li Tuoba uniform speed flows probe has by certain criterion in high and low nip
The multipair pressure port of arrangement, makes it possible accurately to survey mean flow rate.

Different pipelines are installed, so that Li Tuoba flowmeter pipelines are extremely complex, and installation and maintenance are inconvenient.Can also
Increase the unnecessary leakage point for being likely to occur leakage so that danger greatly increases when product is run.Work as Li Tuoba flows simultaneously
When meter is run in the more environment of impurity, it is possible that the phenomenon of positive and negative pressure hole plug, existing in order to solve this problem
There is man of subsidiary factory in the middle part of technology to carry out blowback by the way of blowback pipeline is connected on main pressure pipeline, although so solving anti-
The problem of preventing from blocking is blown, but equally can open up through hole on main pressure pipeline, can also increase and unnecessary be likely to occur leakage
Leakage point so that product run when danger greatly increase.
