Dynamic pressure sensing via a flow sensor
It is recommended to have a measurable differential volume flow in an amount that enables reliable evaluation via a flow
sensor.
The pressure is 1.5 bar. A pressure manometer, an adjustable throttle valve and a flow sensor are required for monitoring.
• Recommendation:
•
Measurement range of the flow sensor: 0.5 l/min - 25 l/min
•
Switching point of the flow sensor: 4.5 l/min
• Throttle valve setting:
•
Status 1 (flow): minimum 7 l/min
•
Status 0 (dynamic pressure): maximum 2 l/min
•
When sensing multiple products, it may be required to adjust the values of the volume flow and the
setting of the throttle
valve to the respective installation.
