What is the difference between vortex street, turbine, and mass flowmeter? I measure natural gas (ordinary steel cylinder 20MPa after pressure reduction) ..
A vortex flowmeter is a volumetric flowmeter that measures the volumetric flow rate, standard condition volumetric flow rate, or mass flow rate of gases, vapors, or liquids based on the Karman vortex principle. Turbine flowmeter is the main type of velocity flowmeter, which uses a rotor (turbine) with multiple blades to sense the average flow velocity of the fluid and derive the flow code or total amount from it. It generally consists of two parts: sensors and displays, or can be made as a whole. LWGY turbine flowmeter, along with volumetric flowmeter and Coriolis mass flowmeter, are known as the three types of flow meters with the best repeatability and accuracy. As one of the top ten types of flow meters, its products have developed into a multi variety and multi series batch production scale. The mass flowmeter is based on Coriolis force and has two parallel T-shaped vibrating tubes inside the sensor. The middle is equipped with a driving coil and the two ends are equipped with picking coils. The mass flowmeter directly measures the mass flow rate of the medium passing through the flowmeter, and can also measure the density of the medium and indirectly measure the temperature of the medium. Mass flowmeter is an important flow measurement instrument. Mass flow meters use thermal sensing measurement. All three types of flow meters can be measured. The advantage of a vortex turbine is its low price, but the disadvantage is that its accuracy cannot be too high, and it will decrease due to sensor wear and tear after long-term use, requiring maintenance and r
2. Gas Turbine Flow Meter Standard (GB/T 21391-2022) proposes three installation methods for turbine flow meters: • Standard installation: upstream straight pipe section ≥ 10 times the pipe diameter (10D), downstream ≥ 5D; • Short pipe installation: equipped with flow regulator, total straight pipe section ≥ 6D; • Compact installation: suitable for intelligent flow meters, allowing for smaller space layout; • Process requirements: The deviation of the inner diameter of the pipeline s
