DRAWDOWN / WATER LEVEL METER PATENT PENDING Links to controller to prevent excessive drawdown during purging and sampling. Drawdown control is now automatic with new low-flow water level meter imiting drawdown is one of the basics of MicroPurge® low-flow sampling. The MP30 Drawdown/Water Level Meter provides a new, simpler way to assure drawdown control. The MP30 performs as a drawdown sensor and control when connected to the MicroPurge basics controllers, and as a high quality water level meter. The MP30 switches between both modes. For drawdown control the meter is turned to MicroPurge mode and the probe is lowered to the point of maximum drawdown. If purging lowers the water level to the selected point, a light and buzzer on the MP30 meter are activated and the controller is signaled to enter a standby mode until the water level rises again. A separate light indicates probe submergence in both modes. MicroPurge® basicsTM MP30 Drawdown Meter Advantages • Provides unique MicroPurge Automatic Drawdown Control. Cable link to basics controller puts pumping on standby mode until the well recovers — automatically! • MicroPurge drawdown mode includes light and buzzer indicators to alert sampling personnel when the selected maximum drawdown point has been reached. • Standard water level mode includes conventional probe submergence light and buzzer indicators. • Available with 150 or 300 foot (46 or 91 meter) chemical resistant polyethylenecoated tape. • Compact 5/8” (16 mm) diameter probe fits narrow or crowded well casings.

MICROPURGE® basicsTM MP30 DRAWDOWN / WATER LEVEL METER Automatic protection against excessive purging The MP30 Drawdown/Water Level Meter is unique. With its link to the basics Controller for automatic drawdown control, you’ll never have to worry about overpurging a monitoring well again. By constantly keeping track of well level for you, the MP30 removes one of the variables that can make low-flow sampling a challenge. Even if distractions occur, you’ll have the confidence of knowing that the well will not be pumped down to excessive drawdown levels that could compromise your sample integrity....
