SMS Based Pump Controller with Automatic Dry Run Shut Off

In this post we are going to construct a SMS based water pump controller with automatic shutdown of pump when no water flow through the pump is detected.  We will also construct another much simpler automatic dry run preventer circuit without GSM in the next half of the article. What is Dry Run in Motors … Read moreSMS Based Pump Controller with Automatic Dry Run Shut Off

Submersible Pump Start/Stop Circuit

The post explains an automatic submersible pump start, stop circuit with dry run protection in order to implement an automatic ON/OFF switching of the motor in response to the high/low water levels of the overhead tank. Circuit Concept In one of the previous posts we learned a similar concept which also dealt with an automatic … Read moreSubmersible Pump Start/Stop Circuit

Borewell Motor Pump Starter Controller Circuit

The post explains a circuit which controls a submersible borewell motor by operating its red (Start) and green (Stop) buttons, in response to low level, high level water conditions, and also in a condition where the motor may experience a dry run situation. The idea was requested by Mr. Vamsi. Automatic Start/Stop Controller for Borewell … Read moreBorewell Motor Pump Starter Controller Circuit

Water/Coffee Dispenser Motor Dry Run Protection Circuit

The article discusses a protection circuit which may be used for preventing a “dry run” situation in mini coffee dispenser motor pumps, by sensing the slight difference in its wet and dry current consumption levels. The idea was requested by Mr. Ken Adler. Technical Specifications I read with great interest your post titled, “Motor dry Running, … Read moreWater/Coffee Dispenser Motor Dry Run Protection Circuit

Underground Water Pump Motor Dry Run Protector Circuit Without Probes

The circuit idea presented here shows a simple method by which  insufficient water conditions inside an underground tank can be sensed without introducing probes inside the underground tank, and thus preventing any possibility of motor dry running. The circuit also incorporates an overhead water overflow control feature. The idea was requested by one of the … Read moreUnderground Water Pump Motor Dry Run Protector Circuit Without Probes

Motor dry Running, Tank Overflow Controller Circuit

The post explains a very simple water level controller circuit which is able to implement and restrict overhead water overflow as well as dry running of the pump motor. The idea was requested by Mr. S.R. Paranjape. Technical Specifications I came across your site while searching for Timer circuit. I am very surprised by seeing … Read moreMotor dry Running, Tank Overflow Controller Circuit
