Explanation on some important functions
Cost indicating function
This function converts and displays the approximate amounts of cost against the
current flow rate in terms of “Total Cost” and “Cost” indications.
Note:
Since an indicated value is approximate, use it only as a rough yardstick.
Calculating method:
(1)
The user is expected to calculate in advance the amount of cost for a unit flow rate
of 1 m
3
compressed air (Compressor efficiency B yen/m
3
) from the compressor
power consumption and unit cost of electricity.
Compressor
Compressor efficiency
B (yen/m
3
)
Flow meter
Flow rate:
A (m
3
/h)
(2)
Set the calculated compressor efficiency B (yen/m
3
) as a “Cost Rate.”
For reference:
The “Cost” (instantaneous cost, yen/h) for while the process fluid is flowing at the
above-mentioned instantaneous flow rate A (m
3
/h) is calculated by the following
formula:
Cost (yen/h) = B (yen/m
3
)
×
A (m
3
/h)
Similarly, total cost (cumulative cost) can be calculated as follows:
Total cost (yen) = B (yen/m
3
)
×
Total flow rate (cumulative flow rate, m
3
)
