Price of nitrogen flowmeterReasonable supply, based on the Karman vortex street theory, utilizing the natural vibration principle of fluids, and using piezoelectric crystals or differential capacitors as detection components, is a velocity based flow meter. This instrument adopts * differential technology, combined with isolation, shielding, filtering and other measures, to overcome the problems of poor seismic resistance and small signal data disorder of similar products. It also adopts * sensor packaging technology and protective measures to ensure the reliability of the product. There are two types of products: basic type and composite type. The basic type measures single signal; The composite type can simultaneously measure temperature, pressure, and flow rate. Each type has a whole or split structure to adapt to different installation environments.
This instrument has a series of advantages such as wide range ratio, high accuracy, easy installation and maintenance, and wide adaptability to media. It can be widely used in the process measurement and energy-saving management of various low viscosity single-phase fluids such as liquids, gases, steam, etc. in industries such as petroleum, chemical, metallurgy, machinery, food, papermaking, as well as urban pipeline heating, water supply, gas, etc.
Price of nitrogen flowmeterAnd its working principle:
In a fluid pipeline, inserting a cylindrical barrier vertically will generate vortices alternately on both sides at its rear (relative to the fluid flow direction). As the fluid flows downstream, a vortex column is formed, which we call the Karman vortex street.
We define the cylindrical barrier that generates vortices as the separation frequency of vortices by the vortex generator under certain conditions, which is linearly related to the flow velocity of the fluid. Therefore, as long as the frequency of vortex separation is detected, the flow velocity or flow rate of the fluid in the pipeline can be calculated.
Characteristics of nitrogen flowmeter:
·More precise control of nitrogen flow can be achieved to save costs;
·Nitrogen flow control can also avoid excessive nitrogen flow, which leads to insufficient heat replenishment;
·Can accurately determine the output of nitrogen gas.
