I believe it is mostly an issue of resolution.
I choose the delta 40 because full scale is zero to 40 cm of head for two reasons:
1. My reservoir is about 20 cm tall
2. Minor variations over the smaller range range will be much more noticeable than the same variation over the the 10 meter range of the 1000 cm unit.
I mean, you could use a 50 hp pump for your loop, but there may be issues. A classic case of bigger is not always better.

The resulution ist the same.
When you measure fill levels: with the Delta40 -> you have a resulting resulution of 0.5mm, total:400mm
with the Delta1000 -> resolution of 12.5mm, total:10000mm
I am not sure I follow sebastian... if the Delta40 has a resolution of 0.5mm and the Delta1000 has a resolution of 12.5mm... does that not make the resolution of the Delta40 25 times finer than the Delta1000?

Yes, if you do the math the right way. The range for both sensors is about 800 steps from the lowest to the highest level.
10000 / 12.5 = 800
400 / 0.5 = 800
So if you use the mps 1000 and would start with an empty reservoir you would have to fill it up to 12.5 mm before the sensor will be able to detect a difference for the first time. In the same situation the mps 40 would have been already recognized 25 different levels. This example is not fully correct but will help to understand the difference.
So using a small reservoir with the mps 1000 is possible but the measurements will be imprecise because of the larger steps.

I believe the resolution IS the accuracy... 0.5 m for the delta40. The unit does not display mm of water column, but percent full.
To calibrate the sensor you provide the maximum fill level of the reservoir and the current fill level in the reservoir, from the bottom of the reservoir.

From Wikipedia
Resolution is the smallest change in the underlying physical quantity that produces a response in the measurement.
Accuracy is the measurement tolerance, or transmission of the instrument and defines the limits of the errors made when the instrument is used in normal operating conditions.
If you use this sensor to estimate the pressure drop across the loop or across a component? Can you post please what is the SW representation?
Thanks again.

I belive it's only a junction.
I found i guide on the net about the installation of the delta 100 as a filling sensor... "this tube is then connected to the “LOW” marked port of the sensor…. THIS TUBE MUST NOT CONTAIN ANY FLUID IT MUST JUST BE FILLED WITH AIR!!!!...."
And an istallation of a delta 500 as a sensor of pressur drop measure and probably i misinterpreted the image.
