What is a gas mass flowmeter? Gas mass flowmeter is an instrument for measuring gas flow rate, which can adapt to various gases such as corrosive gases. The principle is to measure the gas mass and convert it into volumetric flow rate. Widely used in industries such as petroleum, chemical, food, and beverage. Talking about the balance, it utilizes the energy loss caused by resistance when fluid passes through a flowmeter, accurately measuring without being affected by temperature, pressure, or corrosiveness. High precision, stability, long lifespan, supporting flexible measurement range, easy operation and maintenance. Common applications of gas mass flow meters: industrial process control, used to monitor and control various gas flow rates, such as air, hydrogen, nitrogen, natural gas, etc., applied in petrochemical, refining, chemical, power and other fields. The air compression system monitors and controls the compressed air flow, maintains system stability, saves energy, and ensures normal equipment operation. Environmental monitoring, measuring atmospheric gas flow rates such as oxygen, carbon dioxide, etc., used for atmospheric change, air quality assessment, and environmental pollution control. Laboratory research, control and measurement of experimental gas flow rates, such as fluid dynamics, chemical reactions, etc., to ensure experimental accuracy and data collection. In summary, gas mass flow meters play a crucial role in industries, environments, healthcare, and laboratories, monitoring, controlling, and optimizing gas flow rates to ensure safety, reliability, and efficiency. Different types of gas mass flow meters meet different requirements for accuracy, pressure range, and flow range.

2. Types of gas flow meters

There are various types of gas flow meters, including the following. 1. Volumetric gas flowmeter: determines the flow rate by measuring the volume of gas inside the instrument. It uses mechanical measuring elements to continuously divide the fluid into individual fixed volume parts, and then accumulates the total amount of fluid, such as a household gas meter, which measures accurately and is less affected by fluid properties. 2. Turbine gas flowmeter: It works based on the principle that the fluid impacts the turbine rotation, and the turbine speed is proportional to the fluid flow velocity. It has the advantages of high accuracy, good repeatability, and wide range ratio, and can quickly respond to changes in flow rate. It is commonly used for measuring gas flow rates such as natural gas. 3. Vortex gas flowmeter: Place a non flow hysteresis type object in the fluid, and when the fluid passes around the object, a regular vortex column will be formed. The flow rate is measured by detecting the vortex frequency. It has a simple structure, easy installation, and a wide range of applications. 4. Thermal gas flowmeter: It uses the principle of thermal conduction to measure gas flow and is divided into two types: constant temperature difference and constant power. Can directly measure gas mass flow rate, has good adaptability to temperature and pressure changes, and is commonly used for gas flow monitoring in industrial production. Ultrasonic gas flowmeter: calculates flow rate and flow rate by detecting the time difference of ultrasonic propagation in the fluid. It has the advantages of high accuracy, no pressure loss, and bidirectional measurement, and is widely used in the measurement of gas flow i
