Featuring totalizer capability, these flowmeters measure the rate of flow and the cumulative flow volume of conductive liquids such as wastewater, cooling water, and salt water. Also called inductive flowmeters, magnetic flowmeters, or electromagnetic flowmeters, these electrical devices are programmable, making them suitable for applications requiring high precision measurements. They send electromagnetic pulses through the conductive liquid to generate a voltage that is detected by electrodes. The faster the liquid moves, the higher the voltage. With no moving parts, these reliable flowmeters require less maintenance than mechanical flowmeters.
