DL24 EchoPod Ultrasonic Level Switch, Controller and Transmitter

Documentation

DL24 Spec Sheet

Flowline introduces EchoPod, an innovative level sensor that replaces floats, conductance and pressure sensors that fail due to dirty, sticking and scaling media in a small tanks/vessels 9.8 ft. (3m) or less. EchoPod, a general purpose sensor, combines non-contact switch, controller and transmitter capabilities in one multi-function sensor. Combining 4 relays, 4-20 mA output and pump/valve control in one small sensor allows EchoPod to be your total solution. maintenance fress, EchoPod reduces tank system hardware through simplicity and consolidation. Addiotionally, EchoPod is well sutied 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 it's with EchoPod.

Functions:
Switch

4 programmable relays
High or low alarms

  Switch
  High level alarm (1-4) Low level alarm (1-4) Any combination of high and/or low alarms Contact sensors are susceptible to coating and scaling liquids, resulting in sticking / malfunction that requires frequent maintenance or replacement. EchoPod provides a non-contact solution for the retrofit of float trees and conductivity probes. Combining 4 built in SPST relays, EchoPod delivers a reliable, durable and dependable replacement. EchoPod's selectable hysteresis eliminates relay chatter from turbulent media, a feature contact sensors can't provide. Additionally, non-contact sensors are immune to the performance issues influenced by changes in a media's specific gravity. EchoPod's non-contact ultrasonic switch performance is level made simple.

  
  

  Controller
  Auto fill / empty Control 2 pumps / valves Unused relays may be used as additional alarms Contact sensors for control have traditionally been difficult to set up, and don't provide long term maintenance free operation. Conductance and floats are challenged by the lack of programmable level intelligence inherent by design and failure due to contact with the liquid media. EchoPod's user friendly configuration software, WebCal, provides un-matched accuracy and programming for control applications. Multifunction relay control capabilities. Designed out cost through advanced signal processing techniques, EchoPod delivers the next generation of digital processing for control. EchoPod is level control made simple.

  
  

  Transmitter
  Adjustable 4-20 mA output Reversible output Interface directly to local display and / or to PLC, SCADA, DCS systems Remote displays / controllers can increase relay functionality Contact transmitters initially deliver low-costs for OEM specification, but are susceptible to high failure or replacement costs from contact with the application media. EchoPod provides a non-contact replacement of pressure, capacitance and float sensors that require maintenance or replacement from the sticking, scaling or corrosive media. EchoPod enables greater measuement accuracy (± 0.2% of range), resolution (0.039") and repeatability ensurng overall system performance reliability. EchoPod is level measurement made simple.
