Stenner Pump Control Module
The PCM is a component of a feed system that delivers repeatable doses based on water volume. The
proportional feed system includes the PCM, fixed output pump and simple in-line dry contact water
meter. The PCM system is suitable for a variety of applications such as pH control, disinfection and
oxidation of iron, hydrogen sulfide and manganese.
PCM5
0.5 - 5 Seconds, 115 Volt
Contacting Meter
The contacting meters feature a rugged engineered reinforced plastic with union ends and use the
multi-jet principle, which has been an internationally-accepted standard for many years. This type of
meter is known for its wide range, simplicity, and accuracy in low-quality water. The impeller is centered
in a ring of jets, with inlet jets on one level and outlet jets on another. For pulse output, one of the
pointers is replaced by a magnet, which is detected by an encapsulated sensor attached to the outside
of the lens. Pulse rate is determined by the dial on which the magnet is placed. Changing the pulse rate
requires no special tools and can be done in the field. Includes 12 foot lead wire. For use with PCM5.
