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). Referencing the illustrations, follow the below steps to disconnect, mount and reattach the antenna. 1) Loosen and remove the four (4) socket screws using a 3mm Allen wrench. 2) Carefully remove the antenna. Note: Do not remove or damage the plastic cone within the antenna socket. 3) Insert the antenna through the bottom of the fitting. Note: If doing so from the inside of the tank, make sure to secure it, so as to prevent the antenna from falling into the tank. 4) Connect the sensor to the antenna socket and reattach the four (4) screws using a 3mm Allen wrench. 5) Attach the sensor to the fitting as necessary. Add a Flange Remove Screws Remove Antenna Insert Antenna... -
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” (500mm) away from the side wall, or if there is material build up on the side wall (within the beam angle), perform a False Echo Curve during initial configuration. ... - 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. Consider the Dead Band The sensor has a dead band (blanking distance) of 12” (30.48mm) as its default. The dead band can be lowered to within 2” of the bottom of the antenna (consult with factory). This is an up close distance where the sensor is not able ...

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. Find a location where the sensor has a clear view of the liquid surface. If your tank has other equipment near or within the beam path of the sensor, a False Echo Curve should be performed during initial configuration. Fill Stream Mounting Mounting on left incorrectly positions sensor above the tank fill stream inlet. Mounting on right is correct as the sensor has an unobstructed view to the liquid level below. Reflector Installation Mounting on left incorrectly allows the sensor to receive false echo returns from the step. Mounting on right has an angled baffle‐board ... -

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. Note: The use of a stand pipe is not recommended with liquids that significantly coat or scale. As a rule, if the inside wall of the tank has material build‐up, then the inside of the stand pipe will also have build‐up that will affect the sensor’s operation. When installing a sensor in a stand pipe, follow the below guidelines: 1. The Full Configuration setting (20mA) must be below the upper vent hole and the bottom of the antenna. 2. The Empty Configuration setting (4mA) is typically placed at or near the bottom of the stand pipe. 3. The Stand Pipe function must be activated. It can be found under Medium in the Configuration Menu. The inner diameter of the stand pipe must be entered within this function. ... -
Page 23: Sight Glass Installation
INSTALL SENSOR Step Three Sight Glass Installation An alternative to a stand pipe is installing the sensor within a sight glass mounted outside of the tank. Sight glass installations can avoid issues from turbulence, substantial foam or other equipment in the sensors beam path. Note: The use of a sight glass is not recommended with liquids that significantly coat or scale. As a rule, if the inside wall of the tank has material build‐up, then the inside of the sight glass will also have build‐up that will affect the sensor’s operation. When installing a sensor in a sight glass, follow the below guidelines: 1. The Full Configuration setting (20mA) must be placed at or below the upper tank connection pipe. 2. The Empty Configuration setting (4mA) must be placed at or above the bottom tank connection pipe. 3. The Stand Pipe feature must be activated. It can be found under Medium in the Configuration Menu. The inner diameter of the sight glass must be entered within this function. 4. -

Page 60: Empty Configuration
APPENDIX Section Nine Empty Configuration This function adjusts the empty linear scaled current output (4mA) and provides two different adjustment methods: The primary method involves setting the value based upon the distance from the bottom of the sensor. This is a measured value using the units of operation for the sensor. For example, if the units of operation are in meters, then the setting must also be in meters. A second method involves setting a value based upon the percentage of the Range value. For example, if the Range is set to 10ft, then a 10% setting is equivalent to 1ft of liquid height or 9ft of air gap away from the sensor. Note: Set the Range value before setting the Empty Configuration value. Shows the percentage of empty based upon the Range setting. Shows the distance from the bottom of the sensor to the empty tank. Shows the air gap distance from the liquid to the bottom of the sensor. Full Configuration ... -
