OPERATION
MP 30 Operating Instructions
Background
The MP30 Drawdown Control Meter is designed to help control draw-down during monitoring
well purging, especially when used with MicroPurgebasics pump controllers. The MP30 has
3 primary modes of use:
1. When connected to MicroPurge basics controllers, pump operation is automatically
paused if the selected drawdown limit is reached, then resumed when the well recovers
to this point.
2. The MP30 includes light and sound indicators of reaching the drawdown limit (dry probe
condition); these function independently of the MicroPurgebasics controllers, and may
also be used in this way with controllers other than Micropurge basics models.
3. When switched to water level mode, the MP30 provides conventional water level meter
functions of light and sound indication upon contact of the probe with water.
1. Determine static water level in conventional manner, with MP30 power
switched "ON" and Drawdown Control switched to "OFF" (see Figure 1).
2. When well purging is to begin, switch the MP30 Drawdown Control switch
to "ON" and lower the probe to desired drawdown control level.
3. Connect the MP30 to the MicroPurge basics controller with the cable
provided.
4. Begin purging; the MP30 will automatically signal the controller to pause
pumping if the probe is no longer submerged, and will also activate the
buzzer and the "Level Shutoff" light.
5. If the water level in the well recovers and reaches the probe, the basics
controller will resume pump operation and the MP30 "Probe Submerged"
light will activate.
