HC-CMF100 seriesThermal gas mass flowmeter：

It can be used to measure the standard volumetric or mass flow rates of 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 single or mixed gases (excluding acetylene gas) in pipes of various shapes and materials (such as round pipes, square pipes, rectangular pipes, etc., with diameters ranging from 8mm to 50000mm or larger, various 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.

Without temperature and pressure compensation, one meter 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 far exceeds other flow meters;

High precision, high sensitivity, fast response speed, extremely wide range ratio (up to 1000:1), 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 type structure, with a simple and reliable overall structure, requiring minimal installation and maintenance;

No movable parts inside, sturdy 316L stainless steel or tantalum metal encapsulated probe, no pollution, smooth, anti stick, corrosion-resistant;

On site LCD displays instantaneous and cumulative flow rates, standard current or voltage signal outputs, upper (lower) limit alarms, etc;

No need to open the meter 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 phosgene.

Traditional flow meters require temperature and pressure compensation to measure fluid mass flow rate, while the HC-CMF100 series thermal gas flow meter does not require temperature and pressure compensation and directly measures fluid mass flow rate. Its prominent feature is that it can directly conduct trade settlement; No moving parts; Low pressure loss; Wide range ratio; High precision; High reliability; Easy to install and operate. Widely used in industries such as petroleum, chemical, medical, thermal power plants, and environmental protection.
