Hot gas flowmeter [insert type]

Model: WCFM300 series
Features: Wide range ratio, extremely low flow rate lower limit, high accuracy, good repeatability, easy maintenance
  • Product Introduction
The WCFM300 series hot gas flow meter [insert type] is an instrument that uses the principle of thermal diffusion to measure gas flow. It overcomes the disadvantage of inaccurate measurement caused by the presence of water, oil, and impurities in the gas when using a thermal gas mass flow meter based on the principle of constant temperature difference to measure gas flow. It has the characteristics of wide range ratio, extremely low flow rate lower limit, high accuracy, good repeatability, and easy maintenance. It is widely used for gas flow measurement in industries such as metallurgy, power, food, boilers, pharmaceuticals, petrochemicals, and environmental water treatment. It can also be used to measure the mass flow rate of wet gases, such as real-time detection of air volume (speed) in underground gas drainage, air supply, and exhaust systems.
 

  • Features

1、Suitable for measuring various single or mixed gases, suitable for installation in large-diameter circular, rectangular or square pipelines;

2、Platinum thermistor sensor using new patented technology;

3、Wide range ratio, extremely low flow rate lower limit;

4、High accuracy and good repeatability;

5、The requirements for the straight pipe section before and after installation are not high, only 5D before and 3D after installation is sufficient;

6、It is independent of the temperature and pressure of the gas and does not require temperature and pressure compensation. The gas mass flow rate can be directly measured;

7、Wide screen LCD display, direct reading of instantaneous flow and cumulative flow;
