Brand: Automation Products Group Inc. (APG)
Request Information
Favorite
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 difficult 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 affected by foam, vapors, or dust
