MF201The series pipeline thermal gas mass flowmeter can be used for gas flow measurement rise,It can also be used in the field of process control. It introduces advanced technology from the United States for production, without the need for temperature and pressure compensation, and directly measures the mass flow rate of the fluid. Its prominent features Yes: There are no movable parts; Low pressure loss; Wide range ratio; High precision; approve High reliability; Easy to install and operate. Can be fully replaced in all fields Orifice plate and differential pressure flowmeter.

Thermal gas mass flowmeter:Can be used to measure pipes of various shapes and materials (such as round pipes, square pipes, rectangular pipes, etc.), with diameters ranging from8mmarrive50000mmThe standard volumetric flow rate or mass flow rate of various single or mixed gases (excluding acetylene gas) in air, nitrogen, oxygen, ozone, helium, helium, hydrogen, methane, ethane, propane, ethylene, propylene, carbon monoxide, carbon dioxide, laughing gas, sulfur dioxide, hydrogen sulfide, hydrogen fluoride, phosphine, chlorine, ammonia, Freon, isobutane, n-pentane, methane, gas, biogas, various blast furnace coke oven gas water gas semi water gas mixed gas, natural gas, dusty flue gas, chemical mixed gas, etc. (or larger materials such as metals, plastics, cement, etc.). Structurally, it can be combined with various accessories to form pipeline or plug-in flow meters. Typical applications include various gas metering and control in the gas production industry, various gases in the petrochemical industry, and torch gas metering and control; Boiler primary air, secondary air, and coal grinding air in the power industry; Various types of gas, air, and hot air in the steel industry, as well as high-purity gases in the electronics industry; Heating and ventilation in the air conditioning system and nuclear power industry; Air and biogas from aeration tanks in the water treatment industry; Air supply and gas drainage in the coal mining industry; Air in the air-fuel ratio test of engines in the automobile and motorcycle manufacturing industry; Measurement of laboratory gas flow rate, etc.

﹡ No temperature and pressure compensation is required,1The table can directly detect the volume flow rate or mass flow rate of gas under standard conditions;

﹡ The lower limit of flow measurement is extremely low, almost starting from zero, which is incomparable to other types of gas flow meters;

﹡ High precision, high sensitivity, fast response speed, and extremely wide range ratio(accessible1000：1)Especially suitable for trade accounting measurement;

﹡ The pressure loss is extremely small and almost negligible, especially suitable for measuring gases with large diameters and low flow rates;

﹡ Integrated or split structure, simple and reliable overall structure, with minimal installation and maintenance;

﹡ No movable parts inside, sturdy316LStainless steel or tantalum metal encapsulated probe, pollution-free, smooth, anti fouling, corrosion-resistant;

﹡ On site LCD display for instantaneous and cumulative flow, standard current or voltage signal output, on top(below)Limit alarms, etc;

﹡ No need to open the cover to reset the accumulated flow, especially suitable for explosion-proof situations; Power off data protection function;

﹡ Built in memory, online maintenance can be achieved using a computer or reader, without the need to remove the flow meter and re blow the pipeline;

﹡ Optional continuous flow device for online disassembly and cleaning of probes, especially suitable for sticky gases such as coke oven and blast furnace gas, without cutting off pipeline flow;

﹡ Optional rectification device can greatly reduce the requirements for the front and rear straight pipe sections;

﹡ Optional tantalum metal probe for measuring highly corrosive gases such as chlorine and gas.
