HGWRxxxx
Ordering Information
HIGHLIGHTS
- Harness the power of advanced Guided Wave Radar technology
for precise product and interface level measurement with
no moving parts, ensuring unmatched reliability and performance - Delivers proven accuracy in harsh conditions with presence of
vapor, foam, corrosive liquids, and condensation - All flexible probes are detachable and can be cut for a perfect fit
Up to 787 inches / 66 ft
Choose 316L SS or PFA-coated cable option - PFA-coated cable provides resistance against paraffin, build-up, and corrosion, extending lifespan and maintenance cycle
- Accuracy: ±2 mm (0.079″)
- Choose from two output configuration options:
RS485 Modbus with (1) 4-20mA output (default)
or 4-20mA/HART option - Multiple liquid compatibilities
- Transmitter is fully configurable via its user-friendly LCD display
interface or dedicated OleumTech GWR Software - Bright, backlit, always-on LCD for clear visibility in any lighting
- Designed for ease of installation and servicing
- Supports -14.5 to 580 psi operating pressure range
- Supports a wide process temperature range
-40 ˚C to 150 ˚C (-40 ˚F to 302 ˚F) - Zone 0/1, Explosion-proof
Reduce Maintenance and Improve Reliability with Guided Wave Radar
The OleumTech Guided Wave Radar Level Transmitter is designed for liquids in storage tanks, pressure vessels, and process applications. GWR level measurement is ideal for upstream production tanks and separators, midstream collection tanks, chemical tanks, and more!
With no moving parts, guided wave radar provides reliable, low-maintenance level measurement in demanding process conditions. The OleumTech GWR Level Transmitter delivers accurate continuous level and interface measurement, even in applications with vapor, foam, condensation, corrosive liquids, paraffin, or buildup.
