The Kobold electromagnetic flowmeter from Instrotech is the solution for measuring the flow of conductive liquids in applications where the reliability and low pressure loss of a magmeter is desired at an economical price compared to higher end models.
The MIK series offers accuracies of ±2% of full scale, reaction times of 1 second and zero drift with temperature change.
The flowmeter operates according to the magnetic induction measurement principle – current being induced in a conductor as it moves through a magnetic field. The amount of current induced is directly proportional to the velocity of the moving conductor. In the case of the MIK, a conductive liquid passing through the meter body acts as the conductor. The meter body contains a set of electromagnetic coils that generate the magnetic field. Electrodes mounted in the meter body, collect the current whose magnitude is proportional to the rate of flow.
The MIK is solid state and has no moving parts to wear, making it very reliable. Viscous and dirty liquids are measured with no accuracy degradation. The wetted materials for the flow body are either Ryton with 316L stainless steel electrodes or PVDF with hastelloy C electrodes. A variety of fitting styles and materials are available including PVC, PVDF, Polypropylene and stainless steel. Different electronics packages are available including frequency or current outputs, adjustable flow switches and integrated totalisers or batch controllers.
