Use With The Mp30 Level Sensing Water Level Meter - QED MP50 Instruction Manual

Operation
Warning: in the HELD SAMPLE state the pump, tubing and hoses are all under pressure.
DO NOT attempt to disconnect or disassemble any part of the system when it is under pres-
sure. The system is under pressure if the pressure gauge shows a value greater than 0 and
the RED Discharge Cycle Indicator is showing.
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 de-
creases the pressure. The pressure gauge shows the approximate pressure applied to the
pump and reads in units of Feet - H²O. This allows easy adjustment of the throttle giving press-
ures that will produce gentle, non-turbulent flow (normally 10-20 Feet - H²O deeper than 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 MP50 may optionally be used with the
MP30 MicroPurge Drawdown / Water Level Meter. See Figure 4 for an example of the MP50 in
MP mode with the controller in a level paused state enacted by an MP30 meter.
