Flow Throttle Use; Use With The Mp30 Level Sensing Water Level Meter - QED MicroPurge basics MP10UH Instruction Manual

Operation

Flow Throttle Use

The flow throttle is used during sampling to regulate the pressure applied to the pump.
Turning the throttle clockwise increases the pressure and counterclockwise decreases the
pressure. The pressure gauge shows the approximate pressure applied to the pump.This
allows easy adjustment of the throttle giving pressures that will produce gentle, non-turbulent
flow (normally 5-10 psi higher than the minimum requirement of 0.5 psi per foot of pump
depth). For traditional, high volume purging pressure may be increased with the throttle to
maximize pump flow during well purging.
Use with the MP30 Automatic Drawdown Control
The MP10UH may optionally be used with the MP30 MicroPurgeDrawdown / Water Level Meter.
See Figure 5 for an example of the MP10UH in MP mode with the controller in a level paused
state enacted by an MP30 meter.
