EchoPod Level
Switch, Controller & Transmitter
Flowline introduces EchoPod, 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" (1.25 m) or less.
EchoPod, a general purpose sensor, combines non-contact switch,
controller and transmitter capabilities in one package. Combining 4
relays, 4-20 mA output and pump/valve control in one small sensor allows
EchoPod to be your total 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 time to "Think Small and Win Big"
is now, and its with EchoPod.
