10.13 Chemical Flow Metering The Chemical Flow Metering Assembly option adds paddle wheel style flow meter(s) to a chemical injection port (quantity and flowrate based on option selection) This option provides feedback quantifying the amount of chemical used and adds system monitoring and alarming capabilities This option may be required if the chemicals being used are non-conductive or are difficult to measure using conductivity sensors To accommodate different chemical injection rates there are two (2) different types of flow meters, low and high flow The respective flowrate ranges for each type are listed in Table 11: Flow Meter Data
Table 11: Flow Meter Data
Flowrate Range (GPH)
Flow Meter Type
Low Flow
26 - 27
High Flow
53 - 66
NOTES: • The “Low Flow” flow meter should be selected when using accessory 12.2.3 Chemical Pump Assembly – Electronic Metering Pump or 12.2.5 Chemical Delivery Skid – Electronic Metering Pump • The “High Flow” flow meter should be selected when using accessory 12.2.2 Chemical Pump Assembly – Diaphragm Pump or 12.2.4 Chemical Pump Assembly – Diaphragm Pump
10.14 Active Coupler The Active Coupler option adds an active coupler distribution zone to the cabinet washer supply This zone, when combined with an active rack, allows for cleaning of hard-to-access areas of container-like parts (eg, jugs with narrow openings), the insides of long narrow parts (eg, hoses), and other complex parts The following components are added to the system: • Two (2) Pneumatic butterfly valves (PC335 model) or one (1) pneumatic butterfly valve (PC365 model) for zoning of the chamber sprays and the active coupler • One (1) Active coupler, spring-loaded • Associated process piping • System automation for added zone valves

NOTE: • The Active Coupler option is not 3-A/NSF 14159-1 certified
10.15 Spray Rotation Verification The Spray Arm Rotation Verification option adds a 316L stainless steel encased magnet to each spray assembly to confirm rotation during all phases of the cleaning cycle Magnetic proximity switches are mounted outside of the chamber and do not intrude inside the chamber 10.16 Pump Casing The With Casing Drain and Valve option adds a diaphragm valve onto the pump case drain so that it can be fully drainable The valve has the following specifications: • Pump Casing Valve (Low Point Drain): Diaphragm type valve with 316L stainless steel body, PTFE faced / EPDM backed diaphragms, and pneumatic actuator Rotary Spray Arm with Encased Magnets Encapsulated Magnet
