Introduction

Thank you for purchasing a True Echo™ Guided Wave Radar level transmitter from APG. We appreciate your
business and your trust. Please take a few minutes to familiarize yourself with your True Echo™ and this
manual.

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 dicult level measurements easy.

Reading your label

Every APG sensor comes with a label that includes the instrument’s model number, part number, and serial
number. Please ensure that the part number on your label matches your order.
