The Recordall® (RCDL) non-resettable mechanical register is a basic totalizer used for inventory and process control where totalization is the only functional need of the product. The standard RCDL register for the RCDL disc meters is designed for metering liquids up to 120° F and is available in several units of measure. On the Industrial Turbo meters, the register is designed to meter liquids up to 250° F. These higher temperature units are available in U.S. gallons for both styles of meters, in liters for disc meters, and in cubic meters for Industrial Turbo meters. If the higher temperature register is selected for use on the RCDL disc meter, the appropriate higher temperature rated disc meter option must be used.
