Abstract
A submersible well probe sleeve made of a cylindrical tube attached to a submersible pump. The cylindrical tube has a number of slots exposing access to a protective pouch. Inside the protective pouch a fluid level sensing probe is placed. The fluid has access to the pouch through slots in the sleeve. Opposite the pouch at a predetermined level is a number of fluid inlet holes which provide access to the center of the cylinder by fluid in the well. The submersible pump draws fluid into the center of the cylinder past the probe. The submersible well probe sleeve provides a fixed relative position between the probe and the inlets such that the level of the well can be maintained at a precise level and the probe can be installed in the well while under the protection of the sleeve.
