What kind of flow meter is better for measuring blast furnace coke oven gas flue gas? Based on years of field experience, NONCON Instrument recommends thermal gas mass flowmeter.

In order to ensure the use effect, we must first make clear the main components and characteristics of these gases, and then we can select zui flow meter suitable for field use.

Due to the particularity of the blast furnace flue gas from coke oven gas, dust, moisture content, low pressure, low flow rate, usually used meter such as vortex flowmeter, turbine flowmeter can meet the needs of the site environment, along with most of these installation site at high altitude or chimney pipes, most of the pipe diameter and particularly big, so the installation is also a big problem, according to the above analysis and jiangsu audiocodes instrument co., LTD. Years of field experience, plug-in thermal type gas mass flowmeter is a very good choice.

Thermal gas mass flowmeter is an instrument to measure the flow rate based on the principle of heat conduction.The instrument adopts the method of constant temperature difference to measure the gas mass flow accurately.It has the advantages of small volume, high digitization, convenient installation and accurate measurement.

The sensor of thermal gas mass flowmeter is composed of two reference platinum resistance temperature sensors.Using a bridge loop, one sensor measures the flow temperature and the other maintains a constant temperature difference higher than the fluid temperature. The flow measurement can be carried out under high temperature and high pressure conditions.It has the following advantages:

1. The wide range ratio can be used to measure gases with flow rate as high as 100Nm/s and as low as 0.5nm /s, which can be used for gas leak detection.

2. Good seismic performance and long service life.The sensor has no moving parts and pressure sensing parts, which are not affected by vibration to the measurement accuracy.

3. Easy installation and maintenance.Under the condition that the field condition permits, can realize not to stop production to install and maintain.

4. Digital design.Overall digital circuit measurement, accurate measurement, easy maintenance.

If rs-485 communication or HART communication is adopted, the requirements of factory automation and integrated management can also be realized.
