The document discusses different types of flow transmitters used to measure the flow of liquids and gases. It describes vertical and horizontal Coriolis flow transmitters, which measure flow based on the change in kinetic energy of a fluid. It also describes turbine flow transmitters, which contain a turbine rotor that rotates due to fluid movement and generates pulse signals that are processed to determine the flow rate. Finally, it mentions common applications of flow transmitters in industries like water, petroleum, and chemicals.
