Application
Electromagnetic flowmeter for bidirectional measurement of liquids with a minimum conductivity of ≥ 5 μS/cm:
• Acid, alkalis
• Paints
• Pastes
• Water, wastewater, etc.
Measuring system
The measuring system consists of a transmitter and a sensor.
Two versions are available:
• Compact version: Transmitter and sensor form a mechanical unit
PEM-1000ALW
• Remote version: Sensor is mounted separate from the transmitter
PEM-1000NW
