A variety of field permeameters have been developed locally, and are readily available to purchase or to hire.
They speed up analysis (somewhat) and add some degree of accuracy to a simple [[percolation test]] by employing the [https://en.wikipedia.org/wiki/Mariotte%27s_bottle Mariotte bottle] principle to maintain a steady water level (fixed head condition) within the test well.
They have relative benefits and limitations in their use, and as they are proprietary devices, they each have manufacturers specific recommendations for their use.
