Abstract
A deposit monitor comprising a constant head tank which empties into a graduated cylinder and a cylindrical drain fitted with an inner tube which defines an annular space. Water flowing through the constant head tank into the graduated cylinder, if it is deposit forming, will gradually plug the annular space and increase the liquid level in the second tank, thereby providing a simple method for determining whether or not scaling is occurring.
Claims3
A non-clogging deposit monitor for measuring the tendency of inorganic particulate containing water to form scale deposits on equipment surfaces exposed thereto comprising a constant head tank having associated therewith a rough inlet screen, an overflow line, and a head tank drain positioned in its bottom;
- a vertically disposed cylindrical tank having marked thereon volume indicating graduations positioned below the constant head tank drain and adapted to receive the entire discharge from said drain and fitted with a drain tube at the bottom of the cylindrical tank;
- and a conically tipped cylindrical member of smaller diameter than the drain tube positioned concentrically within said drain tube, thereby defining an annular opening between the drain tube and the cylindrical member.
