EchoMax XRS-5
Contact
EchoMax XRS-5 is a short-range ultrasonic sensor for continuous, non-contact level measurement. With a narrow 10° beam angle, it performs accurately in confined spaces and challenging installations.
Key Features
-
Narrow 10° beam angle, ideal for confined spaces or environments with obstructions
-
Fully sealed PVDF copolymer housing with CSM rubber faceplate for superior chemical resistance
-
Measuring range up to 8 m (26 ft) for liquids and sludge
-
IP68 protection rating, enabling full submersion during flooding conditions
-
Easy installation with 1″ NPT or R 1″ BSPT threaded connections
Typical Applications
-
Pump wet wells
-
Open channels and flumes
-
Weirs and overflow structures
-
Filter beds
Technical Highlights & Environmental Resilience
-
Non-contact operation, unaffected by turbulence, foam, or obstructions
-
CSM rubber faceplate resists methane gas, saltwater, corrosives, and harsh chemicals—common in wastewater treatment
-
Optional submergence shield ensures continued accurate output during full submersion
-
Advanced signal processing algorithm ensures stable and reliable measurement
System Compatibility
XRS-5 is compatible with the full range of Siemens level controllers—from basic point-level alarms and simple pump control to advanced systems with communication, telemetry, and SCADA integration.
