Abstract
An apparatus for testing fluid loss characteristics of a test fluid such as drilling mud under static or dynamic conditions, the apparatus having a filter medium cell which has a generally vertically disposed cylindrical wall, the apparatus further including a first chamber which is in open communication with the inner surface of the cylindrical wall and a second chamber which is in communication with the outer surface of the cylindrical wall, there being a generally vertically disposed rotatable shaft which is received internally of the cylindrical wall, the shaft being driven by a motor or the like, the apparatus being capable of providing a differential pressure across the cylindrical wall such that fluid will flow from the first chamber to the second chamber in response to the differential pressure and the liquid passing into the second chamber can be suitably measured and used to calculate fluid loss rate of the test fluid.
