2.5 Interfaces of the HDA eco
2.5.1 Interface flow meter
Take care that the used combination of flow meter and pump fits to the HDA eco.
The HDA eco can only work with a maximum pulse frequency of 240 Hz.
To find out that the used equipment fits to the HDA eco please recheck the equipment
with the following formulas:
Calculation of the pump for a given flow meter:
Maximum flow rate of the pump =
14400
Pulse value of the flow meter
l
min
The used value for the pulse rate needs the unit [pulse/l] for the calculation.
Calculation of the flow meter for a given pump:
Maximum pulse value of the flow meter =
14400
Maximum flow rate of the pump
pulse
l
The value for the flow rate needs the unit [pulse/l] for the calculation.
Calculation example to check the pump for a given flow meter:
Pulse rate of the flow meter: 53,95 pulse/l (FMOG100)
Maximum flow rate =
14400
Pulse rate
=
14400
53.95
= 266.9
