Advantages

• Non-contact and unaffected by head pressures

• High resistance • Self-cleaning effect of sensors • Integrated alarm/point level relay • Fast measuring frequency (4-wire)

• Universally useable due to •Flexible measuring range • Changing, highly viscous or •Remote access via Bluetooth® • Heartbeat Technology
