QED MP30 | Bladder Pump System | Water level meters | Water sampling equipment | Water quality testing

Limiting 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. It is ideal for use with dedicated bladder pumps, protecting sample integrity and assuring the largest reduction in purge volume and sampling cost.

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.

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 over-purging 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.

To use Automatic Drawdown Control, the MP30 is switched to MicroPurge Mode and connected to the MP10 or MP15 Controller with the supplied link cable. When the probe is placed at the selected depth in the well, the submergence light stays on and there is no buzzer.

If drawdown reaches the probe, the level shutoff light and buzzer are activated. The linked controller halts pump cycling until the well recovers and reaches the probe; then pumping resumes automatically.

Accurate ground water level measurement

In Standard Water Level Mode, the MP30 probe submergence light and buzzer are actuated when the probe contacts water. With its premium, stretch-resistant, polyethylene coated steel tape and permanent, recessed calibration markings, it is accurate to 1/100th ft. for consistent, repeatable level measurements.

The MP30 links to the MP10 or MP15 basics Controllers to provide continuous control of well level during low-flow purging and sampling. If the preset maximumdrawdown level is reached, the MP30 signals the controller to put pumping on standby mode until the well level recovers.
