What is a good choice for a flow meter with a flow rate of 40 L/h?

The fluid is free of impurities, has a low flow rate, low viscosity, and exhibits certain electrical conductivity. There is almost no pressure or pressure difference inside the tube.

I have low flow here; a orifice plate wouldn’t be suitable, right?
It is recommended to use a rotameter.
With such low flow rate, it’s probably only possible to choose a rotor
With such a low flow rate, it seems that only a rotameter can be used.
A rotameter should be chosen; for smaller applications, metal tube rotameters are generally used
Use a rotor for vertical pipes, and a baffle flow meter for horizontal pipes
Glass rotameter, with not particularly high accuracy
A metal tube rotameter could be considered, as well as an orifice plate. .
