LASVF Vortex Flow Meter
Lastronic Corporation
Description:
The LASVF Vortex Steam Flow Meter delivers reliable flow measurement for steam, gas, and liquid applications using the proven Kármán vortex street principle. It is an industry-standard solution for boilers, steam distribution networks, petrochemical processing, food manufacturing, and commercial HVAC infrastructure.
How It Works
Fluid flowing past a precision-engineered bluff body generates alternating vortices on downstream sides. Because the vortex frequency is directly proportional to flow velocity, internal sensors capture these microscopic pressure variations or vibrations to deliver accurate, real-time flow measurement.
