RECORDALL® COMPOUND SERIES METERS","The Solution for Rapidly Changing Flow Rates Patented Innovative Design ","Dual System Revenue Protection. When you’re metering a well-populated building such as a hospital, university, apartment complex, or a busy industrial or processing facility, you’re concerned about rapid and wide changes in water demand. Recordall® Compound Series meters combine two Recordall metering systems in one innovative package — our Disc Series positive displacement chamber for low flow, and our Turbo Series measuring element for measuring high flow. Our new compound design has not only eliminated the need for a trigger valve, but has all but eliminated the crossover accuracy concern in compounds.
