Abstract: the power meter scale compared with several kinds of gas flow meter scale before information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Large-diameter gas flow measurement has always been a difficulty in energy metering. In the past, in practice, many with orifice, venturi tube, gas flow meter, ultrasonic power, such as thermal mass flowmeter as detecting element. But they basically has the following problems: the hole. More flow meter manufacturers choose model price quote you are welcome to inquire, here is the power meter scale and the comparison of several kinds of gas flow meter scale before the article details. Large-diameter gas flow measurement has always been a difficulty in energy metering. In the past, in practice, many with orifice, venturi tube, gas flow meter, ultrasonic power, such as thermal mass flowmeter as detecting element. But they basically has the following problems: orifice and venturi mainly exist: (1) resistance losses; (2) measuring take pressure Kong Yi smudgy medium jam; (3) must be installed in the case of block was taken down; and for continuous operation process pipeline, the installation becomes impossible; (4) pipe diameter greater than 1. 0 m orifice plate is not in the national standard ( GB / T2624 - 93). Within the scope of support. Therefore, orifice and venturi gas measurement in metallurgical enterprise application is not ideal. Power of the ultrasonic flow meter and gas is a kind of continuous gas online insertion type flowmeter installation, this was a great convenience to installation and maintenance. But, because of the converter gas contains a lot of dust and water vapor, the flowmeter to meet power flow on each hole between the fluid flow, lead to take pressure hole blockage. Gas ultrasonic also because of the converter gas contains a lot of dust and moisture, dirt probe is easy, the sound wave reflection and diffraction, leads to the inaccurate measurement test, the volatility. I * steel converter gas metering original online with the power of the gas flow meter, ultrasonic, the the problem of zui serious need to tear open come down to clean every week, the loss of the great amount of maintenance and measurement data. Thermal mass flowmeter can also keep online installation gas, but also because of the converter gas contains a lot of dust and water vapor, so actual thermal conductivity characteristics of converter gas has changed a lot, it's caused by inaccurate measurement. If there is a dust accumulation on the sensor, which is equivalent to put sensors in the & other; Winter jacket & throughout; , which makes the measurement value is low; If there is water on the sensor, this will give the sensor & other; Cool & throughout; Measured value is larger. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
