Applications
The fields of application for this magnetic flow meter are diverse:
- Can be used in areas where flow sensors with moving parts (paddle wheel, turbine sensors) cannot be applied due to contaminated media
- Sensor is intended for continuously measuring of flow rates or for dosing / batching of electrically conductive liquids with a minimum of 20µS/cm
- Water distribution
- Chemical feed
- Measuring of cooling water, measuring of waste water
- Cleaning Industry: Dosing of detergents and other additives
- Agriculture: dosing of water, fertilizer, fungicides and pesticides, measuring of water and liquid feed supplements
- Exhaust Gas Cleaning: Dosing of AdBlue
