Flowline XP88/89 Series EchoSafe® Ultrasonic Explosion-Proof Level Transmitter

EchoSafe® Ultrasonic Explosion-Proof Level Transmitter
XP88/89 Series

The explosion proof, two-wire ultrasonic transmitter provides non-contact level measurement up to 10 m in hazardous bulk storage, day tank, and sump applications, and is well suited for challenging corrosive, slurry or waste water Media. Application examples include sodium hypochlorite, waste water and resin. The integral display and push button module enable fast and simple calibration.

• 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
• Fail-safe intelligence with diagnostic feedback for easy troubleshooting
• Display indicates air gap of level height distance in inch or centimeter
