DRAWING NO. 5 — TYPICAL INSTALLATION
Automatic Gas Feed System for Chloramination
NOTE: The sole purpose of this drawing is to show the gas flow path through the REGAL System components
and the order in which these components are connected.
System Example:
Using the theoretical ratio of 4:1 (chlorine to ammonia) and assuming a 100 PPD chlorination system is needed, a 25 PPD
ammoniator would be used. In order to always maintain the 4:1 ratio, the milliamp signal to the ammoniator CANNOT be series looped from the
water flowmeter signal because the chlorine residual analyzer and controller circuitry are continually varying the chlorinator dosage to compensate
for changing chlorine demand. Instead, the 4-20 milliamp signal to the ammoniator MUST be based on the chlorinator’s valve plug position.
The manual dosage adjustment on the flow proportional ammoniator can then be used to maintain the chemical ratio of 4:1. If the theoretical ratio
of 4:1 is not correct for the system in question, the chlorine to ammonia ratio can be increased by decreasing the dosage setting and vice versa.
