GENERAL INSTALLATION
1. Empty the vessel or at least reduce the material level below the length of the cable probe.
2. Determine location of where probe should be on the top of the tank. Consider the following:
a. Cable probe should be at least 12 in (30 cm) away from any metal surface.
b. Do not install unit close to material entry flow. Pouring the product directly onto the cable probe will
give false readings and can cause excessive wear to the unit.
c. Install a deflector plate if it is impossible to distance gauge from the entry location.
d. For round, center fill, center discharging vessels, it is recommended that mounting should be located
at a point approximately 1/3 of the vessel radius from the vessel wall.
e. For other types of vessel shapes, contact the manufacturer for assistance in determining ideal ...
mounting location.
3. Add lubricant or sealant in the 1
4. Insert TDR unit, with weighted end into the silo, and mount the unit to
the top of the tank using a 1
a. If direct mounting is not possible, a nozzle may need to be used.
b. When mounting a nozzle, the diameter of the nozzle must be great
than the height. Take note of additional height due to nozzle; add
as needed to the probe length.
CAUTION: DO NOT USE NOZZLES THAT PENETRATE INTO THE TANK. THIS WILL
DISTURB THE EMITTED RADAR PULSE.
5. Unit should hang straight down into the vessel. See Probe Alignment section for more details about non-
standard situations.
