2. Flow calculation formula for glass rotor flowmeter

The flow calculation formula for glass rotor flowmeter is: Q=K × √ (Δ P) or Q=C × A × √ (2g Δ h/ρ), where K and C are instrument coefficients and Δ P is pressure difference.

. 1. Core calculation formula: Glass rotor flowmeter belongs to variable area flowmeter, and its flow calculation formula is derived based on the principle of rotor Glass flowmeter price

force balance. The most commonly used basic form is: Q=K × √ (Δ P), where: • Q: volume flow rate of fluid (unit: m ³/h or L/min) • K: instrument coefficient (or flow coefficient), determined by the specific structure, rotor shape and material of the flowmeter, usually provided by the manufacturer after factory calibration, and is the core parameter for flow conversion. Δ P: The pressure difference before and after the rotor (unit: Pa), which is balanced with factors such as the rotors gravity, buoyancy, and fluid viscosity during stable flow, and can be regarded as a constant. Another more detailed and physically meaningful formula is: Q=C × A × √ (2g Δ h/ρ), where • C is the outflow coefficient, which is an empirical coefficient related to the Reynolds number and is usually calibrated by the manufacturer. A: The annular gap area between the rotor and the conical tube (unit: m ²) varies with the height of the rotor. • g: Gravity acceleration (9.8 m/s ²) • Δ h: Pressure head difference corresponding to rotor height change bench roll (unit: m) •ρ: Density of the measured fluid (unit: kg/m ³) 2. Flow reading in practical applications. In practical applications, operators do not need to perform tedious calculations. The conical tube wall of the flowmeter is directly engraved with flow scale lines. The method of reading the flow rate value is to observe the scale line corresponding to the highest point (or center) of the rotor, which is the actual flow rate value under the current operating conditions. -Factory calibration: The instrument manufacturer calibrates with water (for liquids) or air (for gases) under standard conditions (usually 20 ℃, 101.325kPa), directly engraving the flow rate value on the pipe wall. 3.
