Placement Notes
Please refer to the tank diagram on the previous page to locate the reference numbers
cited below.
1. Beam should not detect bin bottom.
If this occurs use range extension parameters (on controller where available) to omit
false echoes. For every 1m (3.3 ft.) of tank height you must allow for 0. 1 m (0.3 ft.) of
material surface to reflect the ultrasonic pulses. In most tanks the transducer should be
centered as much as possible (without interference from inlet) for optimum reading
range.
2. Sound beam must be perpendicular to liquid surface.
When mounting the standpipe and ferrule you must ensure that the transducer face is
parallel with the liquid surface.
3. Echo has missed an improperly leveled transducer.
Similar to Note 2, ensure that the standpipe and ferrule are mounted so that the
transducer is face level with the measured liquid.
4. Calibrate under normal conditions.
When performing an empty or full calibration, the tank must contain its normal vapour
and be at its normal temperature.
Notes:
• The transducer is to be used only in the manner outlined in this instruction
manual.
• This transducer is recommended for use with liquids only.
