Kofloc FM31 (TEFLON/PFA) Vortex Flow Meter for Liquids the Model31 Karman Vortex Flow Meter employs the following principle for measurement of flows: When a columnar object (an object that generates vortices) is placed in the flow path of a fluid, regular channels of vortices, called Kar- man vortex channels, are generated at the back of the object. Since the frequency of a vortex generated is linearly proportional to the flow velocity within a given range, the flow amount can be measured by counting the number of vortices.
When the frequency of each vortex generated is detected by the incorporated vortex detector (piezoelectric device), the signal processing circuit outputs a signal which is linearly proportional to volume flow.
KOFLOC strives for thorough quality control at domestic factories. In recent years, we have also been focusing on product development for liquid measurement and control equipment, and we will deliver products that can be trusted as “Fluid Kofloc” to the world.
