🔵 Orifice flow meters are 100+ years old.
🏭 Yet they’re still installed in modern plants alongside the latest “smart” instruments.
💡 There’s a reason for that.
📊 In this short carousel, I’ve broken down the essentials:
⚙️ Principle – Differential pressure across a restriction (orifice plate) is related to flow rate (Bernoulli’s principle).
🧩 Typical elements – Orifice plate + primary tap + DP transmitter + impulse lines.
📐 Important Design Parameters
📏 Beta ratio (β) – Ratio of

Question: What is a final control element in a control loop? Options: A) Sensor B) Control valve C) Transmitter D) Element ▶ View Answer 🔎 Detailed Explanation A final control element (FCE) is the device that physically acts on the process to change the manipulated variable. The most common example is a: 👉 Control valve It receives the controller output signal (e.g., 4–20 mA) and adjusts flow, pressure, level, or temperature ac...
