Product details
Flowline EchoPro LR21 Pulse Radar Liquid Level Transmitter
Flowline EchoPro LR21 intrinsically safe 26 GHz pulse radar transmitter provides continuous level measurement up to 20 m with a 4 to 20 mA analogue and HART digital signal output. Configurable via an integral push button display module or Flowline WebCal software. The non-contact liquid level sensor is intended for chemical storage or process applications in above or below grade tanks of any material.
Features and Benefits
Rugged 316L stainless steel antenna and process mount
Configuration via push button display or WebCal software
26 GHz pulse radar is unaffected by vapour or condensation
12 (30 cm) dead band enables utilisation of the entire tank
LCD displays level in feet or meters with percent of span bar
HART communication in point to point and multi-drop modes
Fail-safe diagnostics with selectable signal fail-safe outputs
Recognition, storage and rejection of false echo signal returns
IP67 stainless steel enclosure with polycarbonate display window
