Abstract
An improved bailer which allows for the variance of flow into the bailer through use of attachments with varying inflow orifice sizes. As the size of the orifice changes, the weight of the apparatus can also be changed allowing for an only slightly negative buoyancy of the apparatus. The attachment may also be designed to include features for filtering unwanted particulates from the sample.
Claims15
An improved liquid sampling device comprising:
- an elongate, substantially cylindrical conduit member having first and second conduit ends;
- a first conduit member terminus;
- a second conduit member terminus, said second conduit member terminus being shaped to generally define a second convex dome extending outwardly from said conduit member at said second conduit end, said second convex dome portion of said second conduit member terminus being substantially centered on the longitudinal axis of symmetry of said conduit member, said second conduit member terminus having an in-take orifice defined therethrough and a valve member for valving passage of fluid through said in-take orifice;
- and
- a flow control insert having a flow control orifice and being sized and shaped for snug, nested engagement with said in-take orifice such that all flow continuously enters or exits said device exclusively via said flow control orifice, said flow control orifice having a cumulatively lesser cross section than said intake orifice.
