The MP10 Controller is a simple and effective way to control the amount of sample you draw from the well with simple increase/decrease keys allowing you to easily set the flow rate for each well. When the MP10 Controller is connected to the MP30 drawdown meter the water level in the well is monitored and the drawdown meter sends a signal back to the controller to pause operation if the water level drops below the position set by the user. Once the level recovers the MP10 begins pump operation again. If you have multiple wells which have the same parameters save your desired settings so you can recall them at the next well by using the ID mode and specifying a 3-digit ID.
