1. Application Example of Gas Mass Flow Meter

Application scenario: Torch gas emission monitoring product advantages: wide range ratio, sensor is not easy to block, can be plugged and cleaned online, suitable for a wide range of gas applications: measurement of air volume for boiler primary air, secondary air, and coal grinding air. Product advantages: easy installation, no straight pipe requirements, low pressure loss, no need for temperature and pressure compensation, can be used under harsh conditions without socks (such as dust, particles, severe wear, low pressure, etc. in the air). Application scenario: measurement of blast furnace gas and coke oven gas. Product advantages: calibrated according to the actual medium composition, can correct component changes, can be cleaned online, and the insertion length can be adjusted arbitrarily. Application scenario: high-purity gas mass flow measurement product advantages: can directly measure quality without temperature and pressure compensation. Flow rate, sensor head highly polished, Can be used for trade settlement applications: measuring the air flow of the interception aeration tank. Product advantages: resistant to dirt and dust, truly pressure free, easy to install on site. Application applications: introducing an appropriate amount of gas into the reactor, controlling the process and quality. Product advantages: hygiene grade 3A, high purity, all liquid receiving surfaces made of stainless steel, wide range ratio

2. Specification for flow meter installation in the flare system

Flow meter installation in the flare system should follow core specifications such as GB/T 3840-2021 "Emission Standards for Pollutants in Petrochemical Industry" and

SH 3009-2013 "Design Specification for Fuel Gas System and Combustible Gas Emission System in Petrochemical Enterprises" to ensure safe discharge, environmental compliance and stable operation. 1. Core specification requirements 1.1 Flow meter selection • Type selection: Differential pressure flow meters (orifice plate, V-cone) are preferred for torch gas flow rate nuclear land stupid measurement, suitable for large pipe diameters, wide range ratios, and complex component gases; Thermal mass flow meters can also be used for accurate measurement of low pressure and small flow rates. Material requirements: Stainless steel (such as 316SS) or Hastelloy should be used for the parts in contact with the medium, which are corrosion-resistant and high-temperature resistant (torch gas often contains corrosive components such as H ₂ S). Range ratio: It should cover normal discharge, emergency discharge and other working conditions. It is recommended that the range ratio be no less than 10:1. 1.2 Installation Location - It should be installed in the vertical or horizontal straight section of the torch main pipe to avoid the influence of flow disturbance components such as elbows and valves. Requirements for straight pipe section: The length of the upstream straight pipe section should be ≥ 10D (D is the diameter of the pipeline), and the length of the downstream straight pipe section should be ≥ 5D to ensure measurement accuracy. Orientation requirement: When installing a horizontal pipeline, the flow meter should be located on the side of the pipeline to avoid the deposition of impurities. 1.3 Safety and Protection • Explosion proof Certification: Flow meters must have ATEX or IECEx explosion-proof certification, with an explosion-
