In district heating/cooling and other systems, signals from flow meters can undergo temperature compensation in a totalizer to measure usage of warm water and other quantities. Here we give an example of how to perform temperature compensation of flow using the YS1700 Single Loop Controller in place of a dedicated totalizer.
In 1973 the ISA (Instrument Society of America) defined 4–20 mADC analog as the standarized signals for industrial measuring instruments, and they are still used today for transmission signals. The following are typical Yokogawa field instruments that utilize these 4–20 mADC transmission signals.
