I would like to ask about the use of flow meters for trade settlement in China

In China, flow meters are widely used in the petrochemical industry, primarily to accurately measure the flow rate of liquids or gases. This is very important for process control, energy measurement, and quality control. However, it is not common to use flow meters as the basis for trade handover, especially in commercial oil storage facilities. Firstly, the measurement results of flow meters are susceptible to various factors such as temperature, pressure, and flow rate; therefore, relying solely on the readings from the flow meter cannot accurately reflect the actual quantity of the product. Secondly, the inbound and outbound operations at commercial storage oil tanks involve large quantities of liquid products, and current flow meter technologies are not capable of providing accurate measurements for such large-scale liquid flows. Finally, errors may occur during the measurement by the flow meter, and relying on this alone as a basis for trade settlement could lead to commercial disputes. Overall, although flowmeters are widely used in the petrochemical industry, there are still some difficulties and challenges in using them as a basis for trade settlement. In China, calculations and handovers are more often carried out using methods such as volume and mass. .

No flow meter needed? Is it the number of vehicles?

General shore tank transfer without a flow meter

Are you considering using a flow meter?

I have this idea, but there may be certain limitations in terms of the manufacturing process

I am a instrumentation supplier. It seems that my company has sold products to oil depots before; the situation is probably similar to yours. Could we become friends and communicate? My WeChat ID is gyqtbs008

I’ve found it; we sold it to an energy company before, ones that operate pipeline oil storage facilities, with settlement taken place in between. It is a trade-grade ultrasonic flow meter

Thank you; volume and mass actually refer to the transfer between shore tanks or ships

Currently, many pipelines and oil depots in China are equipped with a variety of flow meters used for trade handovers (such as turbine flow meters, orifice plate flow meters, mass flow meters, ultrasonic flow meters, etc.), all of which meet the requirements regarding accuracy and repeatability for trade handovers in China.

Trade should use pulse signals or communication methods, not current signals, as current signals result in too large errors.
