NG # 02627-HW-KELLER-003
The Keller Acculevel is a high-accuracy, microprocessor-controlled submersible level transmitter designed for precision liquid level and pressure measurements. Positioned in the upper performance tier of Keller’s level transmitter line, it utilizes 16-bit internal digital thermal compensation to eliminate environmental temperature drift, achieving a Total Error Band (TEB) down to $\pm 0.1\%\text{ FS}$ over its operating window.
