Below is the detailed information of vortex flowmeter compensation products.

Vortex flowmeter compensationCould it refer to a vortex flowmeter with temperature and pressure compensation? Because some people who have just come into contact with vortex flowmeters are unfamiliar with it, they will refer to it as vortex flowmeter compensation when it comes to temperature and pressure compensation. This term also has some truth. Let's take a detailed look at the specific parameters of vortex flowmeter compensation below. Firstly, the product image is as follows:

Temperature pressure compensation vortex flowmeter is mainly used for flow measurement of industrial pipeline medium fluid. Media such as gases, liquids, vapors, etc. Its characteristics are small pressure loss, large measurement range, and high accuracy. When measuring volumetric flow rate under working conditions, it is almost unaffected by fluid density, pressure, temperature, viscosity, and other parameters. Due to the absence of active mechanical parts, it has high reliability and low maintenance costs. The instrument parameters can be stable for a long time. The instrument adopts a piezoelectric stress sensor with high reliability and can operate within a working temperature range of -10 ℃ to+300 ℃. It has analog standard signal and digital pulse signal output. It is easy to use with digital systems such as computers. It is a relatively advanced and ideal flowmeter.

Principle of compensation for vortex flowmeter

As a flowmeter, it is necessary to detect mass flow rate in material balance and energy measurement. At this point, the output signal of the flowmeter should monitor the volumetric flow rate and fluid density, as well as the physical properties and composition of the fluid. These points still directly affect flow measurement.

Vortex flowmeter is a new type of flowmeter based on the Karman vortex principle for measuring fluid flow in closed pipelines. Due to its excellent medium adaptability, it 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, it can measure volumetric and mass flow rates under standard throttling conditions. The ideal alternative product for flow meters.

Installation of compensation for vortex flowmeter

In practical applications, the maximum flow rate is usually much lower than the upper limit of the instrument. As the load changes, the minimum flow rate is usually below the lower limit of the instrument. The instrument cannot work in its optimal working area. To solve this problem, it is common to reduce the diameter at the measurement location to increase the flow velocity at the measurement location, and to choose instruments with smaller diameters for easier measurement. However, this method of reducing the diameter requires a straight pipe section between the reducer and the instrument to be corrected, which is 15D or longer in length and can cause inconvenience in processing and installation.

For ease of use, the battery powered local display vortex flowmeter adopts low-power high-tech and can operate continuously for two years when powered by lithium batteries. Above, it saves the purchase and installation costs of cables and display instruments, and can display instantaneous and cumulative flow on site. This 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, easy installation and maintenance, and long signal transmission. Very convenient. It can be widely used for process measurement and energy-saving management of various liquids, gases, steam, and other single-phase fluids in fields such as petrochemicals, metallurgy, textiles, pharmaceuticals, machinery, water supply, heating, thermal power, and scientific research. Industry. It has received high praise and praise from users in various industries.
