Page 5: Sensor Models
Introduction / Table of Contents (continued) Step One SENSOR MODELS ® Offered in three 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 media 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. -

Install Sensor Step Three INSTALLATION REQUIREMENTS ® EchoPro measures the distance between the sensor and the media surface below. 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 media below including ladders, walls, tank seams, media inflows, rails, other sensors, mixer blades, heating coils, pumps,... -

Page 24: Beam Angle
Install Sensor (continued) Step Three BEAM ANGLE The emitted microwave pulse will expand along its specified beam angle for the entire height of the tank. Place the sensor so that objects will not interfere with the beam path underneath the sensor. The beam angle is a function of the sensor Series and antenna length (where variable). -
Page 25: Gimbal Mounts (For Solids)
Install Sensor (continued) Step Three GIMBAL MOUNTS (FOR SOLIDS) Be aware of antenna’s length and width when using a gimbaled mount. The freedom of movement for the gimbaled becomes less as the riser’s height increases. SOLIDS INSTALLATION TIPS In order to measure as much of the solids volume as possible, the antenna must be aimed at the lowest point within the tank. - Page 26 Install Sensor (continued) Step Three SOLIDS INSTALLATION TIPS (CONTINUED) When using the gimbaled flange, the sensor can easily be mounted to direct the signal energy towards center of the tank. The angle of the sensor will be dependent on the distance down to the bottom of the tank and the distance away from the bottom of the cone.
