Question about Garden
Dear I have two feeding pipes in a tank.One pipe feeds water and other pipe feeds chemical, now I want to control the damper of the chemical feeding pipe by means of stepper motor controlled by a microcontroller 89c8051 according to the flow of water which is flowing from the water feeding pipe, a counter meter is installed on the water feeding pipe.
I need the microcontroller program to conrol the chemical feeding damper by a stepper motor 0~90 degree.
You can suggest any type of stepper motor, I need the microcontroller program which counts the water feeding counter pulses and according to the counts, control the damper of chemical feeding by means of stepper motor (+) and (-).
I shall be very thankful to you.

SOURCE: decreased flow visable.
No they just stop, if your loosing flow it is from a block usually in the suction or quite often in the front of the pump the impeller will fill with stuff. A probe like a screwdriver and a set of needlenose pliers will fix this if you go in through the front of the pump.

SOURCE: hydronic heat water feed valve
You should be ok. Most of the time the boiler are charged to about 10psi and dont have feed valve. You would only feed if you have a slight leak in system. Rus

SOURCE: water flow problem
You probally have some ice still in the feed line to the house. You may have to pull the pump and thaw the line. It should be in the very top of the line. You may be able to force hot air down the caseing. Or ifit is bad you might have to dig up the line from the well to the house and re wrap with heat tape. Good luck.
