The PHP-190 Series of chemical
metering systems are unique
instruments that combine a pulse
frequency controller with a
diaphragm-type pump in one
compact unit. In the control mode,
deviations from setpoint are
converted to pulses which vary the
stroke rate of the metering pump.
As the setpoint is approached, the
pump feed slows down to minimize
chemical loss and overshoot of the
endpoint. Variation of the stroke
rate is controlled by a front panel
potentiometer or through process
controlled operation by external
electric or mechanical pacing or by
closed loop control.
The units are
supplied with foot valve, injection
valve, power cord, and a float level
switch made of polypropylene with
a 1.8 m (6') polyethylene-coated
cable. Polypropylene (-PP) models
include a 3 m and 1.5 m (10' and 5')
length of polyethylene tubing. For
proper control, a holding tank with
a minimum 10-minute residence
time is required.
