Product overview
The low range phosphate analyzer uses the ascorbic acid method to measure low concentrations of
orthophosphate in water samples. The high range phosphate analyzer uses the molybdovanadate
method to measure high concentrations of orthophosphate in water samples.
Refer to Figure 1 for the analyzer overview. The doors can be easily removed for better access
during installation and maintenance procedures. The doors must be installed and closed during
operation. Refer to Figure 2.

Theory of operation
The analyzer uses a pressurized reagent system and solenoid valves to supply sample, reagents
and calibration solutions to the sample cell. At the start of each measurement cycle, sample flows
into the sample cell. When the sample cell is full, reagents flow into the sample cell. A stirrer mixes
the reagents with the sample. The stirrer stops to let the mixture become stable and to let air bubbles
dissipate. The analyzer measures the color of the sample. When the measurement is complete, new
sample flushes the sample cell, and the measurement cycle starts again.
English 5

During a calibration cycle, the calibration solution flows into the sample cell. The analyzer adds the
reagents, measures the color of the calibration solution and calculates the slope of the calibration
curve. The analyzer uses the slope to calculate the concentration of samples.
In the ascorbic acid method 1for low concentrations of orthophosphate, the surfactant reagent
prevents the formation of air bubbles on the sample cell walls. The analyzer uses the absorbance of
this solution as the zero reference, which corrects for interference from background turbidity or color,
changes in lamp intensity or optical changes of the sample cell. A molybdate reagent reacts with
orthophosphate to form a heteropoly acid. The ascorbic acid reagent reduces the heteropoly acid to
a blue color. The analyzer measures the intensity of the blue color and calculates the phosphate
concentration.
In the molybdovanadate method2 for high concentrations of orthophosphate, an acid and surfactant
dissolve particulate matter in the sample and prevent the formation of air bubbles on the sample cell
walls. The analyzer uses the absorbance of this solution as the zero reference, which corrects for
interference from background turbidity or color, changes in lamp intensity or optical changes of the
sample cell. A molybdovanadate reagent reacts with orthophosphate to form a
vanadomolybdophosphoric acid complex with yellow color. The analyzer measures the intensity of
the yellow color and calculates the phosphate concentration.
More information is available on the manufacturer's website.

Drain line guidelines
Correct installation of the drain lines is important to make sure that all of the liquid is removed from
the instrument. Incorrect installation can cause liquid to go back into the instrument and cause
damage.
• Make the drain lines as short as possible.
• Make sure that the drain lines have a constant slope down.
• Make sure that the drain lines do not have sharp bends and are not pinched.
• Make sure that the drain lines are open to air and are at zero pressure.
Sample line guidelines
Select a good, representative sampling point for the best instrument performance. The sample must
be representative of the entire system.
To prevent erratic readings:
• Collect samples from locations that are sufficiently distant from points of chemical additions to the
process stream.
• Make sure that the samples are sufficiently mixed.
• Make sure that all chemical reactions are complete.
Connect the sample stream
Install each sample line into the center of a larger process pipe to minimize interference from air
bubbles or bottom sediment. Figure 6 shows examples of good and bad installation.
English 9

Keep the sample lines as short as possible to prevent the accumulation of bottom sediment. The
sediment can absorb some of the analyte from the sample and cause low readings. The sediment
can later release the analyte and cause high readings. This exchange with the sediment also causes
a delayed response when the analyte concentration in the sample increases or decreases.
Figure 6 Sampling methods

Set the bypass flow rate
N O T I C E
Do not loosen the screw by more than 4 turns for the multi-stream.
The bypass flow can be adjusted when the analyzer is in shutdown mode. Adjust the flow rate of the
sample bypass line with the flow valve as shown in Figure 7 or Figure 8. Refer to Specifications
on page 20 for the sample flow rate range. Use an external meter to measure the flow rate of the
sample bypass line. Increase the flow rate of the sample bypass line when the process stream is far
from the analyzer for a faster response to changes in the process stream.

Connect to the digital inputs
The analyzer can receive a digital signal or contact closure from an external device that causes the
analyzer to skip a sample channel. For example, a flow meter can send a digital signal when the
sample flow is low and the analyzer skips the applicable sample channel. The analyzer continues to
skip the applicable sample channel until the digital signal stops. All sample channels cannot be
skipped. A minimum of one sample channel must be in use.
Note: If all of the sample channels have no sample, the user cannot put the analyzer in shutdown mode with the
digital inputs. To put the instrument into shutdown mode or back into operation remotely, use the optional Modbus
module and write to Modbus register 49937. Write 40007 (decimal) to put the analyzer in shutdown mode. Write
40008 (decimal) to put the analyzer back into operation.
Each digital input can be configured as an isolated TTL type digital input or as a relay/open-collector
type input. Refer to Figure 14. By default, the jumpers are set for isolated TTL type digital input (logic
low = 0 to 0.8 VDC and logic high = 2 to 5 VDC; maximum voltage 30 VDC). Refer to Wiring
