Mass application of smart gas flow meters in the coal industry


Mass application of smart gas flow meters in the coal industry

intelligent   The selection principle of the measurement range of the gas flow meter, under the premise of meeting the measurement accuracy, for the actual flow range of the measured gas (within the range of maximum flow and minimum flow under working conditions), a reasonable selection of the corresponding intelligent gas flow meter selection Specifications, especially with regard to the lower limit of the gas flow.

    台燃气设备时,燃气设备的实际最小燃气流量作为选择最小流量,燃气设备的最大燃气流量作为选择智能燃气流量计的最大流量。 When there is only one gas device downstream of the intelligent gas flow meter, the actual minimum gas flow rate of the gas equipment is selected as the minimum flow rate, and the maximum gas flow rate of the gas equipment is used as the maximum flow rate of the intelligent gas flow meter. 台以上燃气设备的情况下,宜将同一智能燃气流量计下游的燃气设备组的实际最小燃气流量作为选择流量计的最小流量,将同一智能燃气流量计的下游的燃气设备组织的总燃气流量乘以同时工作系数后的流量作为选择智能燃气流量计的额定流量。 When there is more than one gas equipment downstream of the same gas, the actual minimum gas flow of the gas equipment group downstream of the same smart gas flow meter should be used as the minimum flow of the selected flow meter, and the gas equipment downstream of the same smart gas flow meter should be organized The total gas flow rate is multiplied by the flow rate at the same time as the rated flow rate of the selected smart gas flow meter. When multiple gas consumers are installed downstream of the same smart gas flow meter, if the range of a single smart gas meter cannot cover the maximum flow and minimum flow of the gas consumer, consider grouping the gas devices to configure smart gas. The flow meter or special gas equipment is equipped with a smart gas flow meter separately.

    The discharge of smoke, waste liquid, sewage, etc. seriously pollutes the atmosphere and water resources, and seriously threatens the human living environment. 世纪的最大课题。 The state has listed sustainable development as a national policy, and environmental protection will be the biggest issue in the 21st century. To control air and water pollution, management must be strengthened, and management is based on quantitative control of pollution.
