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 and 1.5 m (10 and 5') length of
polyethylene tubing, and operators manual. For
proper control, a holding tank with a minimum
10-minute residence time is required.
