Conductivity monitoring
Measure conductivity to support the agreed blowdown strategy. Setpoints must be selected for your make-up water and treatment programme.

Cabinet, tanks and pumps.
One equipment arrangement.
This tank-based dosing assembly illustrates how controls and chemical feed equipment can be arranged together. Cooling-water selection then adds the appropriate conductivity monitoring, blowdown interface and treatment-programme requirements.

Your application comes first
Make treatment decisions from useful measurements.
Cooling water conditions change with make-up water, evaporation and operating load. Select monitoring and dosing equipment to support the treatment programme defined for your facility.
- Manual dosing and inconsistent operating records
- Conductivity changes that need controlled blowdown
- Separate treatment equipment that needs coordinated operation
- A need for alarm visibility and optional remote monitoring
A coordinated equipment scope
Build the right configuration.
Components are selected to work together. Final scope depends on your application and confirmed technical requirements.
pH & ORP monitoring
Use appropriate measurements where required by the treatment programme. Confirm sensor suitability and sample conditions.
Chemical dosing
Select metering pumps and tanks for the specified treatment chemicals, dose rates, materials compatibility and operating pressure.
Blowdown control
Coordinate conductivity measurement, controller logic and the selected blowdown valve, with suitable operating safeguards.
Corrosion monitoring interfaces
Review any corrosion monitoring requirement and available equipment interfaces with the treatment specialist. Measurements support, rather than replace, the treatment programme.
Remote visibility
Optional data and alarm integration depends on the selected controllers, communication interfaces and site network.
Selection & project support
Equipment that supports your treatment programme.
We focus on equipment supply, system selection, technical support and project coordination. Chemical programmes and site operating procedures should be defined by the responsible project specialists.

Hotels, commercial buildings and district cooling
Map the circuit boundary before selecting treatment equipment. District cooling facilities may include open evaporative tower circuits as well as separate closed chilled-water networks. Their water chemistry and control requirements differ. Identify which circuit the proposal covers rather than applying a tower blowdown design to a sealed network.
Industrial facilities also need a review of process contamination, materials and operating schedules alongside the water analysis.
Flow connects the dosing strategy to operation
Make-up flow can provide a proportional dosing input where the treatment programme and equipment support it. A circulation-flow permissive helps prevent chemical feed into a stopped circuit. Distinguish a measurement used for proportioning from a switch used to confirm flow.
Review the instrument and controller interface principles, then define cooling-specific sensors and sample conditions. See the dosing and monitoring equipment scope for the components to coordinate.
Closed-loop control architecture
Measure the circuit. Act. Measure the response.
In an evaporative cooling tower, evaporation concentrates dissolved salts. A conductivity sensor provides feedback to a controller, which operates the blowdown valve against the agreed settings. After blowdown and make-up water change the circuit, the sensor measures the response and the controller updates its action.
Here, “closed-loop” describes feedback control. It does not mean that an open evaporative cooling tower is a sealed water circuit. Closed cooling systems require a different treatment and monitoring review; evaporation-driven blowdown logic should not be copied into them automatically.
Measurement → controller → action → feedback
- Conductivity sensor measures representative circulating water
- Controller evaluates the reading, setpoint and permissives
- Blowdown valve opens or closes under the agreed logic
- Water condition changes and is measured again
Separate dosing channels follow the selected chemical programme. Define deadband, maximum blowdown duration, flow checks and fault alarms to suit the actual system.
Treatment channels
Each measurement supports a different decision.
Conductivity and blowdown
Review make-up water and circulating-water analysis before selecting conductivity limits. Conductivity tracks dissolved ionic content; it is not a complete scale or corrosion assessment. Temperature compensation and sampling conditions must suit the instrument.
pH and chemical dosing
pH monitoring supports the treatment specialist’s operating window. Inhibitor dosing may follow make-up flow, a timer or a measured residual where suitable equipment is provided. Conductivity alone does not directly measure inhibitor concentration.
ORP and biocide dosing
ORP may support control of an oxidizing biocide programme after site-specific review. It is not a universal concentration measurement. Non-oxidizing biocides may require a scheduled or batch strategy rather than an ORP control loop.
Corrosion monitoring
Corrosion coupons or suitable online probes provide information about metal loss or corrosion behaviour. Confirm materials, placement, exposure or measurement method and interpretation with the treatment specialist. pH and conductivity cannot replace direct corrosion assessment.
Biocide and blowdown coordination
Where the programme requires contact time, coordinate dosing with the permitted blowdown hold period. Define maximum limits and fault behaviour. Automatic dosing does not replace microbiological verification or the facility’s water-management procedures.
Remote monitoring
Agree which values, trends and alarms the BMS needs, then confirm controller protocols and interfaces. Define who receives alarms and what happens if the network fails. Local operating safeguards should remain effective without remote connectivity.
Commission the whole response.
Verify sensor readings, pump delivery and valve operation against the agreed design. Test the response to loss of circulation, low chemical level and invalid readings. Review trends with the treatment specialist before changing settings.
Record baseline water analysis, control settings and inspection responsibilities so operators can distinguish a treatment change from an instrument fault.
Information that improves selection
Share the number of towers or circuits, make-up and circulating-water analysis, system materials, normal operating temperature, make-up flow records, existing chemical programme and controller details. Include available injection pressure, tank space and the required BMS signal list.
Discuss a cooling-water equipment scope ↗Practical questions
Before you specify a system.
Can you supply a complete dosing and monitoring arrangement?
We can coordinate the equipment scope, including appropriate instruments, controllers, metering pumps and dosing systems, based on confirmed project requirements.
Can the system connect to a building management system?
Potentially. Confirm the required protocol, signals and available controller interfaces before equipment selection.
Do you provide a chemical treatment programme?
The website scope is equipment supply and technical or project coordination. A site-specific chemical treatment programme must be agreed with the responsible treatment specialist.
