Page 5: Sensor Models
Introduction / Table of Contents (continued) Step One SENSOR MODELS ® Offered in eight different models, EchoPro is an intrinsically safe, two-wire, pulse radar level sensor that provides a continuous 4-20 mA current output that’s proportional to the liquid level in a tank or sump. Make sure that the model purchased is appropriate for your application. -
Page 6: Operating Principle
Introduction / Table of Contents (continued) Step One OPERATING PRINCIPLE The sensor emits a microwave pulse from its antenna, which travels at the speed of light to the surface of the medium below. A portion of that energy reflects off the medium and returns to the antenna. The time gap between energy emission and receipt is called the “time of flight”, and is proportional to the distance between the medium surface and the sensors measurement location, as at the bottom of the antenna. -

Typically, all measurements from the sensor originate from the bottom of the antenna. Refer to the Measurement Reference Chart to determine the location where measurement originates on your sensor. To ensure reliable measurement, adhere to the following minimum installation requirements: 1) There are no obstructions between the bottom edge of the installed antenna and the surface of the liquid below... -
Page 23: Fcc Conformity
Install Sensor Step Three FCC CONFORMITY This instrument complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this instrument may not cause harmful interference, and; (2) this instrument must accept any interference received, including interference that may cause undesired operation. Changes or modifications not expressly approved by the manufacturer could void the user’s authority to operate the equipment. -
Page 24: Lr16 Antenna Preparation
Install Sensor (continued) Step Three LR16 ANTENNA PREPARATION The LR16 Series antenna (only) may be removed from the sensor to allow a flange or reducer bushing accessory to be attached to the 1 ½” NPT mounting threads and/or, the antenna may be inserted from within the inside of the tank through the bottom of an existing fitting (where the base of the antenna is too wide to pass through the fitting from the top). -
Page 25: Mounting Position
Install Sensor (continued) Step Three MOUNTING POSITION The minimum distance (independent of beam angle) that the sensor can be mounted next to the straight side wall of the tank is 19.7” (500mm) as measured from the sensor centerline to the side wall. If you are not able to install the sensor more than 19.7”... - Page 26 Install Sensor (continued) Step Three MOUNT THE SENSOR PERPENDICULAR TO THE LIQUID LEVEL Always mount the sensor perpendicular to the surface of the media. This will enable the return echoes to reach the sensor. Mounting the sensor off-axis will result in weak return echoes or no return echoes, depending on the degree of angle.
- Page 27 Install Sensor (continued) Step Three AVOID OBSTRUCTIONS IN THE BEAM PATH Do not mount the sensor in or above the fill stream, other equipment (ladders, pumps, mixers) or structures within the beam path of the sensor. Such items can create false echo returns and prevent the actual level from being identified by the sensor.

Page 29: Beam Angle
Install Sensor (continued) Step Three AGITATOR OR MIXER If there are agitators or mixers in the tank, the sensor should be mounted as far away from the blades as possible. Once the installation is complete, a False Echo Curve should be preformed while the agitator or mixer is in motion to map out and eliminate false echo returns from the blades. -
Page 30: Stand Pipe Installation
Install Sensor (continued) Step Three STAND PIPE INSTALLATION To avoid issues from turbulence, substantial foam or other equipment in the sensors beam path, install the sensor within a stand pipe (still well).
