The No. 20L Micromet Pot Feeders are designed to slug or shot-feed chemicals into chilled water systems, hot water boilers, steam boilers, etc. The tank is composed of 11 gauge (20L) Steel while the caps are cast iron. Other installation items such as the shut-off valves, elbows, nipples, strainers, tees, drain cocks, flow indicator, etc. are not included.

The feeder can also be used to introduce Micromet into commercial potable water systems for control of scale, corrosion and red iron staining. When doing so, it is necessary to utilize strainers and the FS01-7P Pyrex Flow Indicator. The flow indicator consists of a transparent Pyrex cylinder, containing a rubber ball, fitted in two castings having 3/4˝ female connections at each end.
