EchoSafe® Explosion Proof Two-Wire Ultrasonic Level Transmitter from Flowline
Application
FM approved explosion proof for use in hazardous applications, the two-wire ultrasonic transmitter provides non-contact level measurement up to 32.8' or 10 m, and is well suited for challenging corrosive, slurry or waste liquids. Push button calibrated, the transmitter is typically selected for atmospheric bulk storage, day tank and waste sump applications located within a classified area. Media examples include sodium hypochlorite, diesel fuel and paint. The integral display and push button module enable fast and simple calibration.
Features
Compact XP enclosure with viewing window and dual conduit ports
Narrow 3" beam diameter enables flexible installation in applications with limited measurement space
Rugged corrosion resistant PVDF transducer and process mount
Display indicates air gap of level height distance in inch or centimeters
Configuration
Calibration is fast and simple with our scrolling single layer menu, three button interface and 6-segment LCD display. Troubleshooting is easy with our unique Setup and Diagnostic feedback modes. Setup displays the transmitter's calibration set points. Diagnostics provides users with a snapshot of sensor performance and application variables.
