Linear Chemical Dose Controller

Current Research

The vertical drop tubing was tested to determine the failure point. Various tubing diameters were tested to determine the failure point. If free fall or open channel flow was observed within the vertical drop tubing, then the dosing would be accurate. We determined that the smallest allowable inner tubing diameter is one quarter inch.

Currently, a preliminary manuscript based on the development and research of the Linear Chemical Dose Controller for a scientific research paper is being written for publication as a journal article.

Previous Research

Linear Flow Orifice Meter (LFOM)

The Linear Flow Orifice Meter riser pipe, LFOM, is located in the entrance tank. It is used in the plant when chemical dose flows are laminar. The LFOM tank creates a linear relationship between the flow rate through the plant and the height of water in the entrance tank so that a float system can be used control the chemical dose.

Chemical Doser

The Chemical Doser creates a directly proportional relationship between the plant inflow tank water level and the flow controller outflow tubing level.

Flow Controller

The Flow Controller maintains a constant head level in a small bottle so that hydraulics can be used to dose a specific chemical flow rate solely by controlling the outflow tubing level.
