Abstract
A method and apparatus for monitoring the fluid level in a well bore to limit fluid drawdown in the well bore to a maximum set level. The user first determines the static water level in the well bore by lowering a sensor into the well bore. The sensor is configured to sense when it makes contact with water, so that the user can be made aware that the sensor has reached the static water level. The user then lowers the sensor to a maximum desired drawdown level. The sensor is then set to sense when it loses contact with the water. The sensor is then monitored to determine if the fluid had has dropped below the maximum desired drawdown level, and an audible and/or visual alarm alerts the user whenever the maximum desired drawdown level is exceeded.
