Keller U.S.-Built Digilevel-EC SDI-12 Convertible Level Transmitter
DESCRIPTION
The Digilevel EC by Keller America is specifically designed for long-term deployment in adverse environments common to remote locations. The heart of this instrument is a state-of-the-art, Swiss-produced pressure sensor that incorporates over 30 years of experience in sensor development. Active error compensation circuitry results in outstanding Total Error Band performance. The Digilevel EC is a convertible instrument which may be used for either submersible level or bubbler pressure measurement. This is accomplished by user-selectable pressure connection caps. The conical cap is designed to promote automatic cleaning of the sensing diaphragm, helpful where the submersible level transmitter is deployed in high-silt condi-
tions. The alternate bubbler transmitter cap provides a 1/8!±NPT female pipe thread for connection to the bubbler apparatus.
Also incorporated into the design are separate electrical and reference tube connections. This design minimizes problems caused by condensation of moisture in the reference tube that is possible in some environments when using all-in-one cabling that incorporates a small diameter reference tube.The Digilevel EC is compatible with all SDI-12 v1.3 commands. In addition, it is capableof operating in several emulate modes for popular SDI-12 level/pressure transmitters including manufacturer specific extended commands. A graphical user interface and Dongle are available options for those who may be unfamiliar with SDI-12 commands.
