Sensor output 1
• Switching signal as limit value for flow rate or flow speed, hysteresis or
window function as normally open or normally closed contact.
• Quantity control by preselection meter.
Sensor output 2
• Switching signal as limit value for flow rate, flow speed or temperature,
hysteresis or window function as normally open or normally closed contact.
• Analog signal (4...20 mA) for corresponding volume flow, flow speed or
temperature.
