LPG gas vortex flowmeter

LPG gas vortex flowmeter is a flow measurement device designed based on the vortex effect principle, which is widely used in the storage, processing and use of liquefied petroleum gas (LPG).

High precision: LPG gas vortex flowmeter in the measurement of work volume flow rate is almost independent of the fluid density, pressure, temperature, viscosity and other parameters, so it has a high measurement accuracy.
Good stability: The flow meter has a simple and robust structure with no moving parts, making it very reliable for long term operation.
Easy maintenance: Due to the simple structure of the flowmeter, and the sensor does not directly contact the medium, so it is very easy to maintain.
Wide measurement range: Vortex flow meters with range ratios up to 1:10 are able to meet the measurement needs of different flow ranges.
Variety of signal outputs: Vortex flowmeter has both analog standard signal output and digital pulse signal output, which is convenient to use with computer and other digital systems.

The LPG gas vortex flowmeter is a flowmeter instrument for measuring the volumetric and total volume flow of gases in closed pipelines, which is explosion-proof and can be used without any problems in explosion-hazardous environments. It has a wide range of applications and can be used in industrial and mining enterprises, oil fields, gas fields, metallurgy and electric power, gas and other departments.

Working principle

The working principle of LPG gas vortex flowmeter is based on the Kamen vortex theory. When a fluid (napr. LPG) flows through the vortex generator inside the flowmeter, vortices are generated alternately on both sides of the vortex generator, and these vortices are called Kamen vortices. The separation frequency of the vortices is directly proportional to the flow rate of the fluid, and by measuring this frequency, the flow rate of the fluid can be calculated. Specifically, when the fluid passes through the flowmeter, the vortex columns formed on both sides of the vortex generator will form a vortex street downstream, and the frequency of the vortex street is detected by the piezoelectric sensor, which is then operated and processed by the flow totalizer to ultimately obtain the flow rate value of the fluid.

Areas of application

LPG gas vortex flowmeter is widely used in petroleum, chemický, metallurgy, heat, textile, paper and other fields, especially suitable for flow measurement during storage, processing and use of LPG. For example, in the filling and unloading process of LPG, vortex flowmeter can accurately measure the flow rate to ensure the safety and efficiency of storage and transportation. In addition, vortex flowmeters play an important role in the processing and use of LPG, helping to achieve accurate flow control and metering.

Caveat

1. Installation Requirements: LPG gas vortex flowmeter has higher requirements for straight pipe section, usually need to ensure the length of straight pipe section of 40D before and 20D after to meet the measurement requirements. At the same time, the installation should be as far as possible from the source of vibration, in order to avoid the impact of vibration on the measurement accuracy.
2. Temperature Limits: LPG gas vortex flowmeter has limited high temperature resistance and cannot measure fluid media with temperature ≥300℃. Therefore, you need to pay attention to the temperature range when measuring high-temperature liquefied petroleum gas.
3. Pipe diameter restrictions: Vortex flowmeter is not suitable for pipe diameter greater than DN300mm, because then the flow coefficient is smaller, may affect the measurement accuracy.

LPG gas vortex flowmeters play an important role in the storage, processing and use of liquefied petroleum gas. However, installation requirements, temperature limitations and pipe diameter limitations need to be taken into account to ensure measurement accuracy and reliability.
