Page 16: Section Three | Install Sensor
Install Sensor Section Three INSTALLATION REQUIREMENTS ® EchoPulse measures the distance between the sensor and the liquid 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. -
Page 17: Lr15 Antenna Preparation
Install Sensor Section Three LR15 ANTENNA PREPARATION The LR15 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 18: Mounting Position
Install Sensor Section 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 19 Install Sensor Section Three Mount the Sensor Perpendicular to the Liquid Level Always mount the sensor perpendicular to the surface of the liquid. This will enable the return echoes to reach the sensor. Mounting the sensor off-axis will result in weaker return echoes or no return echoes, depending on the degree of angle.
-
Page 20: Flange Riser Installation
Install Sensor Section 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 seen by the sensor. -
Page 21: Beam Angle
Install Sensor Section 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 22: Stand Pipe Installation
Install Sensor Section 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). A stand pipe installation can be used with liquids with a dielectric constant as low as 1.9. -
Page 23: Bypass Installation
Install Sensor Section Three BYPASS INSTALLATION An alternative to a stand pipe is installing the sensor within a bypass mounted outside of the tank. Bypass installations can avoid issues from turbulence, substantial foam or other equipment in the sensors beam path. Note: The use of a bypass is not recommended with liquids that significantly coat or scale. -
Page 24: Lr30 Sensor Installation
Install Sensor Section Three LR30 SENSOR INSTALLATION ® The LR30 is unique within the EchoPulse sensor family. It is designed for use in water processing, lift stations, storm water and sump process conditions, which require the sensor to be installed in locations that are often below grade where flooding is a possibility. -
Page 25: Lr98 Display Installation
