Electromagnetic Flow Meter
LF-200 
Obtain type approval(Water Meter)/K-water Performance Sharing system Success
Obtain type approval(Water Meter)/K-water Performance Sharing system Success Key Features
- Minimizes the straight pipe section through the uniform magnetic field distribution technology
- Standardly fitted with a grounding ring (stabilization of flow measurement through the grounding of the fluid)
- Equipped with an on-site calibration function
- Has a circuit board that is coated with synthetic resin, which makes it resistant to vibration and humidity
- Has a built-in lightning arrester and overvoltage protection device
- Equipped with parameter change history storage function
Application of Digital Filters (Multi-sampling System)
◈ 1st: Uses a hardware filter to reduce noise
◈ 2nd: Uses a software filter to reduce noise
Minimization of measurement errors caused by eccentric flow using the uniform magnetic distribution method
