Steam Vortex Flowmeter with Compensation

Overview of Steam Vortex Flowmeter with Compensation

Steam Vortex Flowmeter with Compensation is mainly used for flow measurement of medium fluid in industrial pipelines. Such as gas, liquid, vapor and other media. It is characterized by small pressure loss, large range and high accuracy. It is almost unaffected by fluid density, pressure, temperature, viscosity and other parameters when measuring volumetric flow under working conditions. There are no movable mechanical parts, so the reliability is high and the maintenance is small. The instrument parameters can be stable for a long time. This instrument adopts piezoelectric stress sensor, which has high reliability and can work within the working temperature range of -10 ℃ ~ +300 ℃. It has analog standard signal and digital pulse signal output, which is easy to be used with digital systems such as computers. It is a relatively advanced and ideal flowmeter.

Working priciple of Steam Vortex Flowmeter with Compensation

As a flowmeter, it is necessary to detect the mass flow in material balance and energy measurement. At this time, the output signal of the flowmeter should monitor the volume flow and fluid density at the same time. The physical properties and components of the fluid still have a direct impact on the flow measurement.
Vortex flowmeter is a new type of flowmeter based on Carmen vortex principle to measure the fluid flow in closed pipelines. Because of its good medium adaptability, it can directly measure the working condition volume flow of steam, air, gas, water and liquid without temperature and pressure compensation. Equipped with temperature and pressure sensors, it can measure the standard condition volume flow and mass flow. It is an ideal substitute for throttling flowmeter.

Installing of Steam Vortex Flowmeter with Compensation

In practical application, the maximum flow rate is often far lower than the upper limit value of the instrument. With the change of load, the minimum flow rate is often lower than the lower limit value of the instrument. The instrument is not working in its best working section. In order to solve this problem, it is usually used to reduce the diameter at the measuring point to increase the flow rate at the measuring point, and select a smaller diameter instrument to facilitate the measurement of the instrument, However, this reducing method must have a straight pipe section with a length of more than 15d between the reducing pipe and the instrument for rectification, which makes processing and installation inconvenient.
In order to be convenient to use, the battery powered local display vortex flowmeter adopts micro power consumption high-tech, and the lithium battery powered vortex flowmeter can operate continuously for more than two years, saving the purchase and installation costs of cables and display instruments, and can display the instantaneous flow and cumulative flow locally. The temperature compensated vortex flowmeter has the characteristics of no moving parts, large measurement range, reliable operation, high measurement accuracy, wide medium adaptability, small pressure loss, simple structure, convenient installation and maintenance, and long-distance signal transmission, which brings great convenience to users It can be widely used in the process measurement and energy-saving management of various liquids, gases, steam and other single-phase fluids in petrochemical, metallurgy, textile, medicine, machinery, water supply, heat supply, thermal power, scientific research and other industries, and has been highly valued and praised by users from all walks of life
