True Echo™ Guided Wave Radar
Level Transmitter
Series: GWR200
®
The True Echo™ GWR200 takes the mystery and frustration out of level measurement. With programmable 4-20
mA or RS-485 Modbus outputs, and innovative signal analysis, the True Echo™ can accurately measure solids,
liquids, and slurries at depths up to 80 feet. NEMA 6 housing is standard, and 316 SS or PFTE-coated 316 SS probes
operate in process temperatures from -40° to 398° F. Robust and reliable, the True Echo™ makes dicult level
measurements easy.
FEATURES
• Auto Calibration to any dielectric
• Easy setup with True Echo™ Software
• Range up to 10 feet with SS rod, 80 feet with cable
• Not aected by foam, vapors, or dust
