Other aspects of flow controller performance have also been tested this fall, including maximum inlet head allowable, water level variation in the flow controller, and corrosion resistance of the manufactured float valves. There have also been updates made to the materials used in the flow controller design.

Methods and Results from Specific Experiments

Float valve corrosion test

• A simple test where float valve parts were left in alum and chlorine for extended periods of time to determine corrosion effects

Flow controller body design and selection

• Includes notes on the brainstorming that went into FCM parts selection and design

Flow versus head loss data collection in the turbulent range

• Experiments were conducted to establish a model for the relationship between FCM outflow and headloss associated with outflow tube position

Determining the maximum inlet shut-off pressure

• The maximum inlet pressure that the float valve can shut off was investigated in order to determine how much head there can be between the chemical stock tanks and the flow controllers
