VFM-LWGY Turbine Flow Meter Series

VFM-LWGY series turbine flow meters have the features: high accuracy, good repeatability, convenient installation/maintenance, simple structure etc.
Liquid flows through the turbine housing causing an internal rotor to spin. As the rotor spins, an electrical signal is generated in the pickup coil. This signal is converted into engineering units (liters, cubic meters, gallons etc.) on the local display where is applicable. Optional accessory modules can be used to export the signal to other equipment.
