Calibration function is standard.Calibration measures the actualdischarge volume under the
exact operating conditions and stores that value to ensure the correct injection rate.
• Injection rate can be set three ways:– Stroke speed: 1 to 300 spm– Percentage: 1 to 100%– Direct entry of injection rate in ml/min
• Set points can be easily viewed on the LCD
High Capacity models are available
in material codes VFC, SS and FTC only.VFC model is shown.
To specify pump, choose the type fromthe chart on page 2 plus the size fromthe chart on page 6 (ex: PZi4-31). Thenadd the appropriate material code fromthe chart below (ex: PZi4-31-FFC).Complete instructions regarding Model Number Selection are on page 6.

• The flow checker mounts directly to the discharge of PZ and PZi metering pumps.
• The flow checker is an oval gear flow meter which measures the pump output and transmits one pulse for each 1 ml of flow.
• Flow checker output can be connected to Model PZi8 Pumps for instantaneous indication of pump output displayed onthe pump LCD. The flow checker output can also be connected to a Neptune Model FLC100-B Flow Indicator–Totalizer,
to display both instantaneous flow and totalized flow.
• Connect the flow checker output to your controller or PLC.

MODEL PZiAAutomatic FlowControl ElectronicMetering Pump
Features
• Built-in calibration
• Maintains precise feed rate by correctingfor changes in pressure/viscosity
• Precise batch injection
Benefits
PZiA Electronic Metering Pumps are the first in the world to feature an integratedautomatic discharge volume control. Specialcircuitry allows onboard calibration of pumpflow under actual process conditions. EachPZiA is furnished with a Flow Checker forfeed verification and a constant pressurevalve for the best possible accuracy.
Once calibrated, the pump can be manuallyset or can be controlled by an analog signal.The pump then automatically adjusts byincreasing or decreasing the stroking speedto maintain the precise flow rate regardlessof changes in temperature, pressure, orviscosity. PZiA pump accuracy has beenverified by KEMA.
• Flow rate is averaged over 9 to 90 second useradjustable time period
• Two Alarm Outputs and Displays: Can be assignedto totalized flow for Batch Control
• Remote or Local Reset
• Remote Inhibit Terminals
• Power Requirements: 94 to 264 VAC, 50 to 60 Hertz, 5 VA
• Power Interruption: 30 day memory retention
PZiA also performs precise batch injection. After calibration, a specific amount to be injected is entered on the electronic touch pad.Pump may be started manually or initiated by remote signal. The pumpruns as long as necessary for the oval gear meter to measure the setamount and resets for the next command.

Advantages
• Digital settings from 15 to 300 pulses per minute on PZ models and from 1 to 300 pulses per minute on PZi and PZD models
• High stroking speed ensures more uniform distribution of chemicalat low feed rates
• Pump delivery is constant at any voltage from 94 to 264 VAC single phase and is not affected by voltage fluctuations
• Outdoor use—pump is water and UV resistant. Equivalent to IEC specification IP65. Dust proof, wash down duty (with properelectrical connection).
Applications
• Injection of chemicals to boilers and cooling towers
• Chlorine sterilization for food plants, small-scale water-supplysystems, buildings and swimming pools
