What is a micro gas mass flowmeter? The micro gas mass flowmeter refers to a thermal impulse gas mass flowmeter, which is a high-precision measuring instrument used for continuous measurement of liquid flow in pipelines. It has many advantages such as a wide range of measurement, low pressure loss, and easy installation, making it an ideal product for excavator.

2. Which is less affected by density, mass flowmeter or volume flowmeter?

Mass flowmeter is less affected by density, while volume flowmeter is more affected by density.

1. Differences in core principles.

2. Volume flowmeter: measures fluid volume (m ³/h or L/min), detects volume flow rate through structures such as vortex wheels, orifice plates, vortex streets, etc. The actual mass flow rate depends on density conversion (mass=volume of the body pin multiplied by density).

2. Comparison of Density Effects | Type of Flow Meter | Degree of Density Influence | Reason Explanation | | ---------------------------------------------------------------------------------------------------------------------------------------------- Applicable scenarios of mass flow meters: processes that require accurate control of material ratios (such as chemical reactions and energy metering), media with high density fluctuations (such as liquefied gas and slurry)

2. Applicable scenarios of volumetric flow meters: operating conditions with stable medium density (such as water treatment), cost sensitive and compensated systems. >

IV. Key Points for Selection - If the density of the medium changes by more than ± 5%, priority should be given to mass flow meters - Volume flow meters need to be equipped with temperature/pressure sensors for density compensation, which increases the complexity of the system - Coriolis mass flow meters require high installation conditions for cover excitation, and full pipe flow and vibration control need to be ensured (note: the above technical standards refer to GB/T 20728-2021 "Method for Performance Evaluation of Flow Meters for Process Control" and 2024 industry application data)

3. What are the common types of flow meters?

?

A flowmeter is a commonly used measuring instrument with a wide variety of types, each with different functions and measurement ranges. The following are common types of flow meters: mass flow meters, cluster flow meters, direct flow meters, such as calorimetric, angular momentum, gyroscopic, and double bladed flow meters, which are suitable for measuring small flow gases but are prone to contamination and corrosion. Indirect: Derive mass flow rate by combining it with other instruments such as density meters and volumetric flow meters. Electromagnetic flowmeter: Based on the law of electromagnetic induction, it is used to measure various corrosive liquids such as acids, alkalis, salts, as well as flammable and explosive media, industrial wastewater, pulp, mud, etc. It cannot be used to measure gases, vapors, and liquids containing a large amount of gas, nor can it measure liquid media with low conductivity or high-temperature and high-pressure fluids. Vortex flowmeter: Based on the principle of fluid free oscillation, it is used to measure the flow rate of various media
