---------We are gold supplier in 9 consecutive years
Vortex flow meter is based on Carmen (Karman) vortex principle research and production, mainly for industrial piping dielectric fluid flow measurement, such as gas, liquid, steam and other media. It features a small pressure loss, large measuring range, high accuracy in the measurement of actual volume flow is hardly affected by fluid density, pressure, temperature, viscosity and other parameters. No moving mechanical parts, so high reliability and low maintenance. Instrument parameters can be long-term stability.Steam flow meter piezoelectric stress sensors, high reliability, can work within the operating temperature range of -20 ℃ ~ + 250 ℃ for. Standard analog signals, digital pulse signal output, easily with computers and other digital systems supporting the use of a more advanced and ideal measuring instruments.
1, the body of the table at the same time integrated temperature and pressure compensation compensation function, measurable standard volume flow or standard mass flow rate of the fluid. 2, full of intelligent, digital circuit design, automatically compensates the measured fluid density or standard volumetric calculations. 3, the new digital filtering and correction to make more accurate and reliable flow measurement. 4, battery-powered without external power supply can work continuously more than two years. 5, the new Chinese character dot matrix liquid crystal display, easier to operate.

Vortex Steam Gas Air Mass Flow Meter
------More 30 years’ technology to focus details
1.The generator of vortex mass flow meter is the best .
2.The Stability signal.
The display of Vortex gas flow meter
The Explosion Proof
The Explosion proof of vortex steam flow meter.
Intrinsically safe class :Exd II ia CT2-CT5;
Explosion-Proof :Ex d II CT2-CT5.
In the all kinds of vortex flow meter ,what we should understand of the vortex flow meter?
1.Pulse output without display
Pulse signal type vortex flow meter is by way of pulse frequency, the size of flow rate of the output pulse signal form.
Equipment need to be equipped PLC, data acquisition and display instrument something could acceptable signal.
Based on the equipmet with data acquisition and display instrument ,the price is very cheap of this flow meter.
2. Steam flow meter with Display
This vortex mass flow meter with display is the genaral flow meter.if the equipment not have the data acquistion and display instrument,this flow meter is the best.
This has two power supply :24VDC and battery suppy. 24VDC power supply with 4-20mA output.this could connect with system .
3. Tem&Pressure compensation
The pea&pressure compensation vortex steam flow meter is the best product for steam medium.
The vortex mass flow meter could display the steam pressure and temperature.nest could calculate the density of steam,more over the accuracy is high.
The Vortex gas flow meter from shanghai cixi instrument company
-------80% instruments is for exporting
1. The structure is simple and solid, no moving parts, high reliability, long-term operation is very reliable. 2. Simple installation, maintenance is very convenient of the air flow meter. 3. The detection sensor is not in direct contact with the measured medium, stable performance and long life. 4. the output is proportional to the flow pulse signal, no zero drift, high accuracy of the vortex flow meter. 5. wide measuring range, turndown ratio up to 1:10. 6. the pressure loss is small, low cost, more energy-saving significancein a certain range. In a certain range Reynolds number , the output signal frequency is not affected by the fluid physical properties and composition changes, meter factor only about body shape and size of the vortex, without compensation when measuring the volume of fluid flow, after replacement parts are generally no need to re instrument calibration factor. 7.Wide range of applications, steam, gas and liquid flow can be measured. 8.Test period of two years.
The application of the Vortex steam flow meter
Vortex flow meter flow measurement technology and instrumentation applications generally have the following areas:
Widely used in metallurgy, electric power, coal, chemical, petroleum, transportation, construction, textile, food, medicine, agriculture, environmental protection and people's daily life, and other fields of national economy, the development of industrial and agricultural production, energy conservation, improve product quality an important tool to improve economic efficiency and management level plays an important role in the national economy.
Energy into primary energy (coal, crude oil, coal bed methane, LPG and natural gas), secondary energy (electricity, coke, artificial gas, refined oil, liquefied petroleum gas, steam) and energy carriers working fluid (air, oxygen, nitrogen, hydrogen, water);
Flue gas emissions, waste, sewage and other heavily polluted air and water, a serious threat to the human environment. National sustainable development as a national policy, environmental protection will be the biggest problem of the 21st century. Pollution of air and water to be brought under control, we must strengthen management, and infrastructure management is a quantitative amount of pollution control.
There are five ways: Railway road, air, water, and pipeline transport. Wherein the pipeline transport, although it has long been, but the application is not common. With the outstanding environmental issues, pipeline transport characteristics attracted people's attention. Pipelines must be equipped with the meter, it is the control, allocation and scheduling eyes, is also not safe and economic accounting supervisor essential tool.
Air flow meter install ation with long distance,you need the signal output .For example :4-20mA .
The bady material is stainless steel ,so it has a long working life.
In the Food and sanitation indsutry ,The vortex flow meter has special installation .
The gas flow meter must easy yo clean.
the way of installation is special .
When your working condition like this .you must note in the inquiry email.
