Abstract: the working principle of the intelligent vortex precession flowmeter
scale and installation requirements information produced by excellent flow meter
, flow meter manufacturer to offer you the quotation.
Intelligent vortex precession flowmeter principle: when along the axial flow of the fluid at the entrance into the flow sensor, the blade force fluid into the rotary motion, thus vortex occurred in the vortex flow, vortex flow rotation in the venturi tube, to shrink.
More flow meter manufacturers choose model price quote you are welcome to inquire, here is the working principle of the intelligent vortex precession flowmeter scale article details and installation requirements.
Intelligent vortex precession flowmeter principle: when along the axial flow of the fluid at the entrance into the flow sensor, the blade force fluid into the rotary motion, thus vortex occurred in the vortex flow, vortex flow rotation in the venturi tube, reached the contraction section of throttling the vortex flow speed up suddenly, after the vortex flow into the diffuser, due to the effect of reflow forced precession type quadratic rotation, the rotation frequency of vortex flow is proportional to the medium flow rate, and linear.
Piezoelectric sensors to detect the weak signal charge after preamplifier amplification, filtering, plastic into frequency is proportional to the velocity of the pulse signal, zui to count to send totalizer. especially after processing.
Intelligent vortex precession flowmeter installation requirements: in use process, intelligent vortex precession flowmeter requirement for straight pipe before and after.
If the measured gas contains larger particles or long fibers sundries, need to install the filter.
Have a certain request for air flow and the flowmeter, the gas being measured for single phase, continuously flowing through a pipe, pipe flow;
Before the gas flowing through the meter, the flow rate must be parallel to the pipe axis, can not have vortex flow;
Airflow should be subsonic, a pulse, its flow changes over time is slow, but to be on the safe side, zui to meter the front-end pressure regulating valve installation, to ensure the flow smooth, stable.
For ease of maintenance, do not affect fluid by flowmeter calibration and maintenance of normal delivery, requires the installation of the flowmeter by-pass pipe should be set up, and should ensure the flow downstream zui, short straight pipe;
Flowmeter in addition to the common horizontal installation, can adopt vertical installed, when mounted horizontally, but instead must ensure that the flow of fluid from the top.
Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
In an age when mass flow meter is increasingly important, the researchers believe manufacturers should pay close attention to their results.
Satisfying our customers with the appropriate level of quality is a primary goal and a fundamental element as mass flow meter of our business mission.
Knowing what promotions are popular and get the most activity as mass flow meter from current and potential customers can play a role in your overall strategy.
mass flow meter also offers several other rosemount vortex flow meter that could potentially be useful for manufacturers.
People tend to want what they perceive they cannot have. Making Sincerity seems exclusive or as if it will go out of stock if they don't act quickly often makes it more enticing to the consumer and increases the likelihood that they will buy in.
