CF-200 algae bloom monitor

Track chlorophyll A in fresh or sea water to support intake protection, algae-bloom warning and water-quality decisions.

A continuous chlorophyll-A trend for your water

The CF-200 algae bloom monitor combines a C-Fluor fluorescence probe, bypass assembly, display and transmitter for continuous chlorophyll-A measurement. It is supplied as an integrated assembly on a 316 stainless-steel backplate.

Chlorophyll A is a primary pigment in algae. Its fluorescence measurement provides an indicator of changing algal biomass in fresh or sea water, helping operators recognise conditions that may affect an intake or treatment process.

The CF-200 is part of PMA’s Turner Designs and associated water-monitoring offering. Its measurement is chlorophyll A, with a separate role from the TD-550, TD-560 and TD-120 oil instruments.

CF-200 chlorophyll-A monitor and flow-cell assembly

CF-200

Designed for continuous water-quality information

An operational algae indicator

Track changes in chlorophyll-A response rather than relying solely on intermittent samples. Review seasonal behaviour and the site’s operating context when interpreting the trend.

Plant alarms and output

The display/controller provides two alarm relays and a 4–20 mA output. Agree signal scaling, thresholds and the operator response with your control-system team.

Accessible bypass assembly

The isolation and bypass arrangement provides access for cleaning. The instrument uses no chemicals or reagents and has no moving parts in its measurement assembly.

Technical details for your specification

Published manufacturer specifications are a starting point. Confirm the supplied configuration, target sample and installation conditions with PMA.

Measurement principle

Chlorophyll-A fluorescence using the C-Fluor probe. Published chlorophyll measurement range: 0–100 µg/L.

Process connection

1-inch PVC union fitting with threaded or socket connection. Confirm the supplied connection and pipework arrangement.

Wetted materials and pressure

Titanium metallic and CPVC wetted parts; maximum pressure 3 bar (45 psi). Review material compatibility for your water.

Output and alarms

4–20 mA output, loop or internally powered, plus two 3A form-C alarm relays on the display/controller.

Electrical supply

85–275 VAC supply to the display/controller; maximum power consumption 20 W.

Controller environment

NEMA 4X / IP65 display-controller rating; published controller operating range −40 to 65°C. These controller ratings do not define the complete sample/probe operating limits.

Applications for chlorophyll-A monitoring

Seawater intakes

Recognise changing algae-related conditions before they affect industrial processes using seawater. Site conditions, season and weather can change the background.

Desalination pretreatment

Use the chlorophyll-A trend to support intake and pretreatment decisions ahead of reverse-osmosis membranes. Agree thresholds for the specific installation.

Freshwater sources

Discuss a representative bypass sampling point for reservoir, lake or river water. Include flow, cleaning access and the meaning of the seasonal baseline.

Water-treatment operations

Combine continuous information with site observations and laboratory sampling where needed. Confirm the intended operational response to rising chlorophyll A.

Interpret the trend in the context of your site

A chlorophyll-A measurement does not identify every algal species and does not directly measure cyanotoxins. It should inform the site’s monitoring programme alongside other observations and analyses required for the risk being managed.

There is no single alarm threshold suitable for every water body or treatment process. Define the normal baseline, seasonal variation, sampling arrangement and action level with the responsible site team.

PMA can help review the installation, control signal and access for maintenance. Provide the water source, expected chlorophyll-A range, process pressure and the decision the alarm should support.

Questions to help you choose

Is chlorophyll A the same as an algae species count?

Chlorophyll A is a pigment-based indicator of algal biomass. A fluorescence result does not automatically identify species or translate into a universal cell count.

Does the CF-200 measure cyanotoxins?

No. The CF-200 measures chlorophyll A. If toxin risk is part of your monitoring objective, include the appropriate additional sampling and analysis.

How should the alarm threshold be set?

Use the site’s baseline, seasonal conditions, sampling setup and treatment objectives. Agree the threshold and the operational response for that installation.
