The phrase "allow flow through" is correct and usable in written English.
It can be used in contexts where you want to indicate that something is permitted to pass or move through a particular space or medium.
Example: "The design of the filter is intended to allow flow through while trapping larger particles."
Alternatives: "permit passage" or "enable movement".
Table 2 shows the chemical compositions of the filtered groundwater in each sample interval volume from the 09MI20 and 10MI26 boreholes during purging of groundwater by allowing flow-through in the boreholes.
This second test allowed flow through firms which are very capital intensive but not as labor intensive to qualify for the lower rate.
Both micropipettes were connected to a single reservoir system and were gradually adjusted to set the intraluminal pressure of the vessel at 85 mmHg without allowing flow through the vessel lumen.
The smaller scale exploited the high surface area of the interior, while on the larger scale, the porosity allowed flow through the post, decreasing the width of the boundary layer and increasing the frequency of collisions of particles with the post.
The beds are placed on a geotextile barrier, which allows water to flow through, but not soil.
To provide the rapid medium changeover required for this study, a perfusion filter (Pall Corp., Supor 800, #60109) was incorporated into the cultivation chamber41 to allow medium flow-through, while maintaining cells inside the growth chamber.
When we get less hung up on how we commune with the infinite source we become more available to how much good we can allow to flow through us and into the world.
However, these channels are typically not large enough to allow a flow through of nanospheres, at least not nanospheres in the size scale used in this study.
This original experimental setup allows performing flow-through experiments with continuous in-situ data acquisition of pressure, temperature, flow rate, pH, and dissolved CO2 concentration.
