Hydrogen mass9/3/2023 There are mainly the following types of gas flow meters: Read more about: Types of biogas flow meters Installed in the pipeline to record the amount of gas flowing through.Ĭan measure blast furnace gas, coke oven gas, coal gas, air, nitrogen, acetylene, phosgene, hydrogen, natural gas, nitrogen, liquefied petroleum gas, hydrogen peroxide, flue gas, methane, butane, chlorine, gas, biogas, carbon dioxide, Oxygen, compressed air, argon, toluene, benzene, xylene, hydrogen sulfide, sulfur dioxide, ammonia, etc. Guess you like: Industrial Oxygen Flow Meters More Featured gas flow metersĪ gas flow meter is an instrument for measuring the flow of gas. Precession Vortex Gas Flowmeter reference price: DN50, USD 600.00/pc. Such as compressed air, oxygen, biogas, natural gas, coal gas, etc. Precession Vortex Gas Flowmeter can be made into an integrated temperature and pressure compensation. The intelligent precession vortex flowmeter can only measure gas. The cost performance of the intelligent precession vortex flowmeter is higher than vortex flowmeter. Precession Vortex Gas Flowmeter, like vortex flowmeter, is a velocity flowmeter. In order to accurately measure the hydrogen flow rate, it is necessary to use real flow calibration for the flow meter calibration. It is inferior to the thermal gas mass flowmeter in the small flow measurement characteristics.ĭisadvantages of thermal gas mass flow meters: the high flow rate range is not as good as Coriolis mass flow meters. The shortcomings of Coriolis mass flow meters: large pipe diameters are bulky, inconvenient to install, and extremely expensive to purchase. They are very popular measuring instruments. These two types of flow meters have advanced measurement technology, good long-term application stability, and extremely low on-site maintenance costs. The sensor connection method has flange connection, flange to clamp connection, thermal gas mass flowmeter can also provide large pipeline plug-in connection.Ĭoriolis mass flowmeters and thermal gas mass flowmeters can provide up to 0.5% accuracy due to their excellent detection technology, which has huge advantages in trade settlement and measurement. Therefore, the system pipe joint used Be reduced to a minimum. Because the pressure sensor interface and temperature sensor are not required to correct the flow reading to the volume flow under the standard state. The sensors of Coriolis mass flowmeter and thermal gas mass flowmeter are all welded. The fluid contact surface is made of 316L, which improves the durability and safety of field application. Both of these are flow meters for direct mass flow measurement, and neither have movable parts and have a large range. Including natural gas, coal gas, liquefied gas, flare gas, argon, carbon dioxide and other mixed gas flow measurement.Įxtended reading: Gas Mass Flow Meter Mass flow measurement of hydrogenĪt present, the Coriolis mass flowmeter and thermal gas mass flowmeter are the most reliable and the most reliable hydrogen flow measurement applications. Thermal gas mass flow meters are designed based on the principle of thermal diffusion. No temperature and pressure compensation is required. Thermal Mass Flow Meter is a true mass flow meter. Unaffected by changes in viscosity, density, temperature, or pressure. Thermal Mass Flow Meter can directly measure the mass flow of various gases. Since the minimum ignition energy of hydrogen (0.02mJ-one order of magnitude smaller than the minimum ignition energy of hydrocarbons) is very small, strict precautions must be taken to prevent leakage. Under normal pressure, a mixture with a hydrogen content of 4.0% to 74% can be flammable. With a molecular weight of 2, and a specific gravity of 0.0695, hydrogen is considered the lightest gas, more than 14 times lighter than air (mv=28.8). Hydrogen (chemical formula H2) consists of two hydrogen atoms, which is colorless, tasteless, odorless, non-toxic, and flammable.
