Automated Chemical Doser Design
Unknown macro: {float}
The automated chemical doser (ACD) has three principles components: a float, a lever arm, and a flow control module (FCM).
The float is a PVC tube capped at both ends and filled with sand. Insert dimensions. It rests in a virtual grit chamber, which is a deep bucket with a pressure sensor at its base. This pressure sensor provides readings of the water level in the bucket.
