7.5.1 Calculating the Totalizer Count Rate Manually
Analog Mode
Example:
Eng Hi = 2500 l/m. Totalizer required to increment in m
3
.
Volume unit conversion: 1 l = 0.001 m
3
.
Source time units = minutes, count rate units = seconds.
Time unit conversion: 1 min = 60 s.
If the input source is at a fixed rate of 2500 l/min, the totalizer increments at 0.04167 m
3
/s.
If the input source is reduced to a fixed rate of 1250 l/min, the totalizer increments at:
Count Rate =
Eng Hi (of source) x volume unit conversion
time unit conversion
Count Rate =
2500 x 0.001
= 0.04167 m

1250
x 0.04167 = 0.0208 m
