Steam flow meterIt is an instrument for measuring the cumulative mass flow rate of steam, with two structural forms: mechanical and intelligent; Through the indicator dial (mechanical) or LCD display screen (intelligent) on-site display, the mass of all steam flowing through the meter can be accurately read, and pulse signals can also be output. It also has manual pressure compensation or automatic temperature compensation functions.Zhejiang steam flowmeter manufacturerDue to its simple structure, moderate price, and wide measurement range, this flowmeter is widely used in various applications such as petroleum, chemical, textile, and heating that require steam flow meters.

Zhejiang steam flowmeter manufacturerSteam flow meterPrinciple:

A volumetric flowmeter that measures the volumetric flow rate, standard condition volumetric flow rate, or mass flow rate of gases, vapors, or liquids based on the Karman vortex street principle. And it can be used as a flow transmitter in automation control systems.

The principle of fluid oscillation is applied to measure flow rate. When the fluid passes through the vortex flow transmitter in the pipeline, two columns of vortices proportional to the flow velocity are alternately generated up and down behind the vortex generator in the triangular column. The release frequency of the vortices is related to the average velocity of the fluid flowing through the vortex generator and the characteristic width of the vortex generator. It can be expressed as follows: where is the release frequency of the vortices, in Hz; v is the average velocity of the fluid flowing through the vortex generator, in m/s; D is the characteristic width of the vortex generator, measured in meters; St is the Strouhal number, dimensionless, with a numerical range of 0.14-0.27. St is a function of Reynolds number,. When the Reynolds number Re is within the range, the St value is about 0.2. In measurement, it is important to meet the Reynolds number of the fluid as much as possible, at which point the vortex frequency is. Thus, by measuring the vortex frequency, the average velocity v of the fluid flowing through the vortex generator can be calculated, and the flow rate q can be obtained from the equation, where A is the cross-sectional area of the fluid flowing through the vortex generator.

Steam flow meters, due to their excellent medium adaptability, can directly measure the volumetric flow rates of steam, air, gas, water, and liquid without temperature and pressure compensation. Equipped with temperature and pressure sensors, they can measure standard volumetric flow rates and mass flow rates, making them an ideal alternative to throttling flow meters.
