Pulse Radar Liquid Level Transmitter

LR16

Application

The intrinsically safe 26 GHz. pulse radar transmitter provides continuous level measurement up to 98.4’ (30m) with a 4-20 mA analog and HART digital signal output, and is configured via its integral push button display module or HART communicator. The non-contact liquid level sensor is intended for petroleum, water, wastewater and diluted chemical storage or process conditions in above or below grade tanks of any material. Select this sensor for challenging process conditions with low or non-corrosive

media, light surface foam or agitation, higher temperature or

pressure, condensation or vapor, and installation in a tank adapter, flange fitting or metal stand-pipe. Typical applications include bulk storage, tanker truck, RO storage, process tank, waste sump and neutralization tanks.

Features

Rugged 316L stainless steel antenna and process mount

Configuration via push button display or HART communicator

26 GHz. pulse radar is unaffected by vapor or condensation

12” (30cm) dead band enables utilization of the entire tank

LCD displays level in feet or meters with percent of span bar

Optional display mode indicates the echo signal return curve

Fail-safe diagnostics with selectable signal fail-safe outputs

Recognition, storage and rejection of false echo signal returns

IP67 stainless enclosure with polycarbonate display window

Antenna Selection

The sensor is offered in three antenna sizes including 2” (48mm), 3” (78mm) and 4” (98mm). The larger the antenna, the narrower the beam and the stronger the RF signal return. To select the appropriate antenna size, consider four variables; The height of the tank, the amount of unobstructed measurement space under the sensor, the thickness of any surface foam and the dielectric of the liquid. In general, the taller the tank, the lesser the free measurement space, the thicker the surface foam or with dielectric values less than 10, consider an increasingly larger antenna.

NOTES

If you want help in selecting a sensor for your application, please go to our

website and submit a Level Questionnaire. An engineer will review your

requirements and suggest a product solution via email.

To install the sensor with a flange or reducer bushing, order the fitting

separately, and follow the antenna preparation instructions in the manual.
