Quick Review
•What is Karman Vortex?
When an obstruction is placed in the flow of fluids, swirling vortices are formed. This repeating pattern of vortices is named Von Karman vortex street, in honor of the physicist Theodore von Kármán. Under set conditions, the number of vortices formed inside a tube is proportional to the flow of fluids running through that tube. By counting the number of vortices, one can identify the flow quantity.
• Simple Construction
The KOFLOC Karman Vortex Flow Meter FM0101/0102/0103/0105 SERIES is small, light and simple in construction without weighing only 205 g, or less. It is highly reliable in measuring small flows of numerous types of liquids including pure water, basic and acidic mediums.
•KOFLOC Dependability
KOFLOC has 60 years of experience in manufacturing precision flow instruments. KOFLOC products, both standard and off-catalog custom items are well received throughout Japan as the name that manifests confidence. KOFLOC, the fluid expert, is the name professionals trust in precision control of minute flow.
•Reliability
The KOFLOC Karman Vortex Flow Meter FM0101/0102/0103/0105 SERIES has no moving parts, making it highly durable and reliable. There is also no error induced by directional orientation and pressure loss is minimal.
•Isolated Sensor
The KOFLOC Karman Vortex Flow Meter FM0101/0102/0103/0105 SERIES has a non-wetted flow sensing element that is isolated from the flow of liquids, making it ideal for process monitoring using many types of liquids.
