Introduction to range ratios for balanced flow meters

Project Overview

　　1. The concept and significance of range ratio. As the name suggests, range ratio refers to the ratio of the measurement range of the flow meter. Specifically, it is the ratio of the maximum measurement range to the minimum measurement range. For a balanced flowmeter, the range ratio directly affects the flow range that the flowmeter can adapt to and the measurement accuracy.

　　In the industrial production process, the flow rate of fluid often fluctuates with changes in production load and process conditions. If the range ratio of the flow meter is too small, the measurement may be inaccurate or even impossible when the flow rate fluctuates greatly. A balanced flow meter with a high turndown ratio can adapt well to this flow change and ensure accurate measurement results under various working conditions. In addition, the range ratio is also related to the flexibility and economy of the flow meter. When the production process changes or the production scale is expanded, the balanced flow meter with high turndown ratio can adapt to the new measurement needs without replacement, thus reducing the cost and trouble of replacing the instrument.

　　At the same time, this also reduces the number of inventory tables to facilitate management and prevent fund backlogs. 2. Practical application cases In order to better illustrate the advantages of balanced flow metering range ratio, several practical application cases are listed below: 1. Steam measurement in chemical production: In the chemical production process, steam is an important heat medium medium. Flow measurement is essential to ensure the stability and safety of production processes. Due to the different amounts of heating and humidification required in different seasons or at different times of the day, the steam flow rate will fluctuate greatly. Traditional flow meters are often difficult to adapt to such fluctuations, while balanced flow meters with high turndown ratios can accurately measure steam flow and ensure the smooth progress of the production process.

　　2. Crude oil measurement in oil pipeline transportation: During the oil pipeline transportation process, the flow rate of crude oil will fluctuate with changes in pipeline pressure, temperature and other conditions. Balanced flow meters with high turndown ratios can accurately measure crude oil flow, providing a strong guarantee for the safety and efficiency of pipeline transportation.
