Product Description

The Rosemount 499ACL-02-54-VP is an advanced total chlorine sensor engineered to continuously measure total chlorine levels in municipal and industrial water treatment systems. Part of Rosemount’s 499 series, this sensor utilizes a gold cathode and silver anode to deliver stable electrochemical measurements when paired with a compatible sample conditioning system and transmitter. The -VP designation indicates a Variopol quick-disconnect plug, which lets you swap out the sensor body effortlessly without pulling long lengths of cable through conduit.

Product Parameters

• Manufacturer: Emerson / Rosemount
• Sensor Type: Total Chlorine Amperometric Sensor (Model 499ACL-02)
• Measurement Range: 0 to 10 ppm (mg/L) as Cl_2 (extendable with system setup)
• Operating Temperature: 32 to 122 °F (0 to 50 °C)
• Operating Pressure: 0 to 65 psig (101 to 549 kPa abs)
• Wetted Materials: Noryl (PPO), Gold, Viton, EPDM, and Silicone
• Process Connection: 1-inch MNPT threaded connection
• Cable Connection: Variopol (VP) watertight quick-disconnect plug

Product Advantages

• Quick Maintenance: The Variopol cable system lets you disconnect the sensor instantly during routine service without rewiring the control panel.
• Easy Membrane Replacement: Features a simple screw-on membrane cap that doesn’t require specialized tools.
• Built-In Compensation: Automatically adjusts for changes in membrane permeability caused by fluid temperature fluctuations.

Important Considerations and Precautions

• Sample Conditioning Requirement: Total chlorine measurement requires a steady chemical sample pretreatment setup (such as adding acetic acid and potassium iodide) to convert bound chlorine species.
• Pressure and Temp Limits: Never exceed the maximum rating of 65 psig or 50 °C to prevent membrane rupture or electrolyte loss.
• Electrolyte Maintenance: Periodic refilling of the internal fill solution and membrane replacement are necessary to maintain measurement accuracy.

Product Applications

• Drinking Water Treatment: Monitors disinfection levels in municipal water plants and distribution networks.
• Wastewater Disinfection: Tracks total chlorine residual before treated effluent is discharged into the environment.
• Industrial Cooling Towers: Controls chemical dosing in high-capacity industrial cooling and process water loops.
