FMM FS-50 + DC pump

[Charles Silva]

Is there a way using FMM FS-50 to create a program controling a DC pump to keep it with the same output flow ? My application will be to keep constant my calcium reactor efluent that once a week I need to open the valve to keep the samw flow.

Using the variable 1-10 port with a DC pump. Is there programming language to accomplish this?

Not really. The apex can't do P, PI, or PID control loops. You can create stepped thresholds using multiple flow statements in the format below by tweaking flow values and percent values. The example below is a target value of 100 gph and 50 percent usually being the correct value to achieve that flow. This requires the latest firmware to use the percent feature. If you aren't current you either need to update or use profiles instead of the percentages.

Set 30
If flow < 120 Then 40
If flow < 110 Then 45
If flow < 100 Then 50
If flow < 90 Then 55
If flow < 80 Then 60

You might be an engineer if...You have no life and can prove it mathematically.
