From Mode press the and then the or to select Level,Range, Flow,
HRT or Volume.
Range mode displays distance from the sensor to the target or liquid surface
like a tape measure. Range mode is useful to measure the exact
distance from the sensor to the zero level during calibration, or to
monitor "outage" or free space in a tank.
Level mode can be used to measure tank level in linear units, or "Head"
(height of flow) in an open channel for comparison with a flume
manufacturer's flow tables.
Volume Volume mode displays tank inventory in engineering units like
gallons or liters.
HRT Horizontal Round Tank mode sets the SLT 5.0 to calculate and
display volume units in a horizontal round tank.
Flow mode is for open channel flow through a flume or weir.
From Volume HRT or Flow press to make your selection. (Range or
Level mode will bypass the Volume units selection menu). Volume Hrt or Flow
modes will give you the additional choice of volumetric units:
