Fill Height:
The maximum depth measured by the EchoFlo. Refer to the EchoFlo Quick Start Guide for
further details.
Sensor Span:
Is the difference between the sensor output at the top of the “
Fill Height
” (2000Hz) and the
sensor output at the bottom (976Hz).The frequency output of an EchoFlo has a span of 1024Hz .
Manually calculating Offset
Offset = - (Slope x Sensor output at zero)
Metric example - you wish to calculate the slope and offset for an EchoFlo that has been configured with a
“ Fill Height ” of 0.75m (75cm).
The following calculations will provide the sensor’s slope and offset:
Slope
= 0.75 ÷ (2000-976)
= 0.75 ÷ 1024
= 0.00073
Offset
= - (0.00073 x 976)
= - 0.71484
US example - you wish to calculate the slope and offset for an EchoFlo that has been configured with a “ Fill
Height ” of 30”.
The following calculations will provide the sensor’s slope and offset:
Slope
= 30 ÷ (2000-976)
= 30 ÷ 1024
= 0.02929
Offset
= - (0.02929 x 976)
= - 28.59375
NOTE: Be sure to record the relevant values for “ Slope ”,“ Offset ”, and depth units.
