1. What is compressed air flow meter mainly used to measure? Compressed air flow meter is mainly used to measure the instantaneous flow rate, cumulative bending flow rate, and gas parameters under working conditions of compressed air. 1. Core measurement object • Volume flow rate: the air flow rate under standard operating conditions (20 ℃, 1atm) or actual operating conditions, usually measured in Nm ³/h or m ³/h. • Mass flow rate: calculated through temperature and pressure compensation, commonly used in kg/h per buried slag position. • Cumulative flow rate: used to calculate energy consumption or production, such as the total output of an air compressor. 2 Key parameter measurement • Pressure range: 0-1.6 MPa (for conventional industrial use) or special high-pressure models • Temperature range: -20 ℃~80 ℃ (for models with PT100 temperature sensors) • Accuracy level

1.5 level (economic type) or 1.0 level (high-precision type) 3 Typical application scenarios - Air compressor outlet flow monitoring - Pneumatic equipment gas consumption detection - Compressed sock source air pipe network balance debugging - Energy Management System (EMS) data acquisition 4. Technical implementation methods: Thermal mass flow meter (direct measurement of mass flow) Vortex flow meter (with temperature and pressure compensation) Ultrasonic flow meter (non-contact measurement) Note: GB/T 34036-2017 standard in 2023 stipulates that industrial gas flow meters must have Modbus RTU communication protocol.

2. What is the accuracy level of the flowmeter? The accuracy classification of flow meters is mainly determined based on the maximum allowable error expressed as a percentage of the instrument (excluding the percentage sign). The higher the accuracy level, the smaller the measurement error of the instrument, that is, the higher the accuracy of the instrument.

1. Accuracy level classification standard Level 1 standard instrument: Its accuracy level includes 0.00

5, 0.0

2, 0.05.

. These instruments are typically used for high-precision measurement and calibration work. Secondary standard instrument: Its accuracy level includes 0.

1. 0.

2. 0.3

5. 0.5. These instruments are used as standard instruments in situations where precision requirements are slightly lower. General industrial instruments: Their accuracy level is usually 1.0, 1.

5, 2.

5, 4.0. These instruments are widely used in various industrial fields to meet general measurement needs. In addition, attention can be paid to the Yangpai optical quantum multiphase flowmeter and Yangpai resonant flowmeter, which are mainly based on Yangpai optical quantum phase separation measurement technology and Yangpai resonant phase separation measurement technology. The Yangpai quantum phase separation measurement manual judgment mixed phase flow fluid technology is a technique used to study mixed phase flow. Different phase fluids have different attenuation effects on light quanta of different energy levels. By measuring the attenuation degree of light quanta of different energy levels, the phase separation rate of different phase fluids in mixed phase flow can be obtained; The Yangpai resonant phase separation measurement technique is based on the principle of resonance. By changing the measured resonant frequency conversion, the mixed density of the medium is measured to obtain the gas and liquid phase separation rates.
