Flow sensor

[jurdim]

Can there be a flow sensor like this:

Flow-sensor

Measures the flow rate of the return pump respectively of the external filter
is connected at the level input of the ProfiLux
reliable and low-maintenance due to measurement without dirt-sensitive moving parts
incl. PS/2-M12-cable (2 m) to connect with ProfiLux
available in 2 measurement ranges
Please note: Shipment without connectors for hoses or pipes!
Articlenumbers:

PL-0866: Measurement range 100 - 2000 l/h, Nominal width DN10, 2x G1/2" outside thread
PL-0867: Measurement range 300 - 5000 l/h, Nominal width DN20, 2x G1" outside thread

Only then for ponds that can measure flows up to 20000 liters per hour and has a 63mm connection ?

Or shorter: No, it´s not possible, you need to set up a bypass.
