Design and Build of Electronic Volume Corrector (EVC) Using Web-Based Microcontroller

Abstract

In the metering industry, an electronic volume corrector (EVC) is essential for collecting measurement data and compensating for standard readings, as mandated by the directorate general of oil and gas. Over time, advancements in data delivery systems have increased the demand for data accessibility and affordability. To address this, a prototype EVC with web-based reading capabilities was developed, allowing users to access and manage data efficiently without needing to visit a physical location. This research aims to implement the EVC not only to maintain accurate corrections but also to enhance ease of access for users in the metering industry. The web server is accessible only to authorized users in the database. Testing using the REST API protocol demonstrated appropriate accuracy for both local readings and those on the web server. In addition to being sent to the web server, data was also sent via Telegram. The average errors produced were 0.0132%, 0.0052%, and 0.0690% compared to the AGA 7 standard at Kelton. This indicates that the EVC prototype has a response system that meets a tolerance of ±1%, matches the capabilities of standard reading correctors, and facilitates data accessibility
