  • Ultrasonic Flow Meter : Working Principle, Advantages

    Ultrasonic Flow Meter Working Principle. An ultrasonic flow meter construction can be done by using upstream and downstream transducers, sensor pipe and reflector. The working principle of ultrasonic flow meter is, it uses sound waves to resolve the velocity of a liquid within a pipe. There are two conditions in the pipe like no flow and flowing.

  • How Do PID Controllers Work | PID Working Principle

    Apr 17, 2019 · The working principle behind a PID controller is that the proportional, integral and derivative terms must be individually adjusted or "tuned." Based on the difference between these values a correction factor is calculated and applied to the input. For example, if an oven is cooler than required, the heat will be increased.

  • How does a Rotameter work? by Premier Control Technologies

    A Rotameter is a form of variable area flow meter which has a simplistic operation whereby a liquid or gas passes through a tapered tube. In order for this gas to pass through the tube it must first raise a float held within the tube. When a rotameter is used with a liquid the float rises because of a combination of the velocity head of the fluid and the buoyancy of the liquid.
