EchoPod® Ultrasonic Level Switch/Transmitter/Controller

Loop Powered 4-20 mA Output, Range To 49.2" (1.25 m)

Description

EchoPod is an innovative level sensor that replaces floats, conductance and pressure sensors that fail due to dirty. sticking and scaling media in small tanks 49.2" (1.25m) or less. EchoPod, a general purpose sensor. combines non-contact switch, controller and transmitter capabilities in one package. Combining 4 relays, 4-20mA output and pump/valve control in one small sensor allows EchoPod to be a solution. Maintenance free, EchoPod reduces tank system hardware through simplicity and consolidation. Additionally. EchoPod is well suited for corrosive and dirty applications with its non-metallic housing and transducer. EchoPod provides a total solution for fluid handling and automation.

The rugged PVDF enclosure is well suited for a wide range of corrosive, waste or slurry type media, and can be broadly selected for atmospheric day tank, process vessel or dispenser, pump lift station and waste sump applications. Level indication can be monitored via a local display or controlled through a PLC.

FEATURES

• Provides switch, controller and transmitter capabilities
• Replacement of multi-point float, conductivity and pressure level switches
• WebCaI™, an innovative PC user interface that provides fast and accurate configuration
• Compact sensor with 2" dead band and beam width optimized for small tank applications
  49.2" (1.25m) or less
