Foreword
The natural gas ultrasonic flow meter is an instrument that uses the characteristics of ultrasonic waves propagating in gas to measure gas flow. This flow meter is widely used in the field of natural gas. Its working principle and characteristics are as follows:
Operating Principle
The natural gas ultrasonic flowmeter measures gas flow by transmitting and receiving ultrasonic signals.
When the ultrasonic signal propagates in the pipeline, its propagation speed is related to the flow rate of the gas in the pipeline.
The flowmeter can calculate the gas flow rate by measuring the propagation time difference of the ultrasonic signal in the downstream and upstream directions, combined with the pipeline size and gas characteristics.
Features
High precision: The natural gas ultrasonic flowmeter adopts advanced measurement technology and has high measurement accuracy, which can meet the high-precision requirements of natural gas measurement.
Wide range ratio: The flowmeter has a wide range ratio and can adapt to the measurement needs of different flow ranges.
No pressure loss: Since the ultrasonic flowmeter adopts non-contact measurement, it will not cause pressure loss to the gas in the pipeline.
No need for regular maintenance: Ultrasonic flowmeters have no moving parts, low failure rate, and long-term use accuracy remains unchanged, so no regular maintenance is required.
Strong pollution resistance: For gases containing impurities, ultrasonic flowmeters can still maintain high measurement accuracy.
Versatility: Some ultrasonic flowmeters integrate flow, temperature, and pressure measurement, and can automatically compensate for temperature, pressure, and compression factor.
Applications
Natural gas ultrasonic flowmeters are widely used in petroleum, chemical, electric power, metallurgy, industrial boilers and other industries, as well as natural gas high-pressure long-distance pipelines, provincial and municipal distribution station metering management, urban gas metering management, natural gas coalbed methane exploitation and utilization, liquefied natural gas and liquefied petroleum gas, large-scale industrial gas metering management, blast furnace gas and coke oven gas metering and other fields.
Latest Developments
With the continuous advancement of technology, natural gas ultrasonic flowmeters are also developing continuously.
In summary, natural gas ultrasonic flowmeters have been widely used in the natural gas field with their advantages such as high precision, wide range ratio, no pressure loss, and no need for regular maintenance, and are constantly being improved and upgraded with the continuous development of technology.
