Vortex flowmeter is a velocity flowmeter, which measures the volume flow rate in the working state. If you choose the table according to the volume flow rate, the mass flow rate provided by the customer should be converted into the volume flow rate under the working state, and then determine the diameter of the selected instrument against the volume flow parameter.
At present, there are many misunderstandings about steam measurement in China, and many users often think that buying a high-price flowmeter can get accurate measurement results. The measurement of steam is different from other fluids such as water, air and other media, and there are many factors affecting its measurement in the actual measurement. Therefore, there is often a phenomenon that the flow meter itself is qualified, but the actual measurement is not “allowed”. So what’s the problem with these factors?
1, pulse vortex flowmeter is a kind of high measurement accuracy, simple installation, small maintenance, a wide range of meters, is currently widely used in petrochemical, metallurgy, textile, urban construction, energy and other industries.
The working principle of vortex flowmeter is to place a non-streamlined vortex generator in the fluid, so that the fluid is alternately separated on both sides of the generator, releasing two series of regularly staggered vortex flowmeter. In a certain range, the vortex separation frequency is proportional to the flow rate, and the vortex flowmeter can measure the flow rate of the medium by calculating the vortex separation frequency.
Integrated intelligent vortex flowmeter troubleshooting
In the production process, each of the intelligent vortex flowmeters has passed a strict quality inspection, and each flow real flow calibration. If the meter does not work properly during use, please follow these steps to check.
Vortex flowmeter can be widely used in large, medium and small kinds of pipeline water supply and drainage, industrial circulation, sewage treatment, oil and chemical reagents and compressed air, saturated and superheated steam, natural gas and various media flow measurement and can be used as a flow transmitter in automatic control system, long service life. Points of attention for vortex flowmeter installation:
Vortex flowmeters are suitable for measuring the mass flow and volume flow of superheated steam, saturated steam, compressed air, general gas, water and low corrosive liquids. We often encounter the following failures in the use of vortex flowmeters:
