Natural gas energy metering ultrasonic gas-focusing microfluidic control technology

Ultrasound technology has reached a fairly mature level and it has been widely accepted by various testing groups. However, if it is to be widely used in the future like other technologies such as turbines and orifice meters, ultrasonic flowmeters have to be technically and economically specific to do so, in order to have an expected market share in the future. In addition to the well-known volumetric flow measurement in natural gas transmission pipelines, there will soon be a major need to measure the energy content of natural gas at remote and arbitrary locations, such as production sites and gathering transmission lines.

Natural gas energy meter

Natural gas energy meter system. It is based on a new type of ultrasonic flowmeter for financial and trade settlement. This type of flow meter is designed to be used at a traditional ultrasonic measurement point, as it is used in the field. The real scene today does not use ultrasonic flowmeters. The functions of the entire system, such as operating under solar power, powerful data transmission, and wireless communication technology, make it ideal for remote areas. In addition to the well-known advantages of ultrasonic flow meters, the system provides a true self-diagnosis function based on the speed of sound inspection, so it satisfies the system's characteristics in remote areas. It is very important to reduce the labor costs associated with the maintenance and repair of the flowmeter and will ensure that the measurement data has a good degree of credibility.

An energy metering system using ultrasonic flow measurement technology. In the world, natural gas is bought and sold in energy units. In natural gas pipelines, there is no separate flow meter that directly measures energy. The energy metering system consists of a gas flow meter that measures volume flow, a gas composition analysis device with an automatic sampler, and a universal calculator. Gas flow measurement techniques used in energy metering systems range from simple orifice plates, turbine meters, to the latest "ultrasonic gas flow meters." The system described here takes advantage of the low energy consumption of each component so that the system can be fully powered by solar-charged batteries. Alternatively, both AC and DC power can drive the various components of the system.
