Description
What Is a Chemical Metering System?
A chemical metering system is an integrated equipment package used to measure, control and inject a specific quantity of chemical into a process stream or vessel.
These systems can be configured for applications such as:
- Chemical dosing
- Chemical injection
- Chemical mixing
- Chemical batching
- Process treatment
- Water treatment chemical dosing
- Corrosion inhibitor injection
- pH control
- Disinfection and chemical treatment
- Process conditioning
- Industrial chemical handling
The system can be supplied as a compact skid-mounted package or engineered as a larger automated chemical dosing installation according to the project requirements.
Chemical Metering Skid Components
Depending on the process and chemical being handled, a chemical metering skid may include:
- Positive displacement chemical metering pumps
- Chemical storage or day tanks
- Calibration pots
- Suction and discharge piping
- Isolation valves
- Check valves
- Pressure relief valves
- Pulsation dampeners where required
- Flow meters
- Pressure gauges and transmitters
- Level instruments
- Chemical injection quills
- Strainers and filters
- Control valves
- Skid-mounted piping assemblies
- Electrical control panels
- PLC-based control systems
- Touch-screen HMI
- Local instrumentation
- Emergency shutdown and alarm systems
The final equipment configuration is selected according to the chemical characteristics, required dosing rate, operating pressure, temperature, material compatibility and process requirements.
Positive Displacement Metering Pumps
Positive displacement pumps are commonly used in chemical metering applications because they can provide controlled and repeatable flow over a defined operating range.
Pump selection can be based on factors such as:
- Required chemical flow rate
- Discharge pressure
- Chemical properties
- Chemical concentration
- Operating temperature
- Required turndown
- Required dosing accuracy
- Pumping viscosity
- Material compatibility
- Continuous or intermittent operation
Depending on the project, different pump technologies and configurations can be considered to meet the required process conditions.
Automated Chemical Metering Systems
Aegis Projects can integrate chemical metering skids with programmable automation and touch-screen HMI controls.
An automated system can provide functions such as:
- Automatic dosing control
- Flow-based chemical injection
- Batch dosing
- Pump start/stop control
- Flow monitoring
- Pressure monitoring
- Tank level monitoring
- Alarm indication
- Low-level protection
- High-pressure protection
- Pump status monitoring
- Process interlocks
- Local HMI operation
- PLC-based sequencing
- Remote monitoring or control where required
Automation can help maintain consistent dosing and reduce manual intervention during normal plant operation.
Custom Chemical Metering Skid Design
Every chemical dosing application can have different process requirements. Aegis Projects develops chemical metering packages according to the specific requirements of the facility.
The skid can be engineered around:
- Chemical type and compatibility
- Required dosing capacity
- Operating and design pressure
- Operating temperature
- Pump configuration
- Number of dosing points
- Required storage capacity
- Piping material
- Wetted component materials
- Instrumentation requirements
- Electrical requirements
- Automation requirements
- Installation environment
- Space limitations
- Applicable project standards
Skid construction and wetted materials can be selected according to the chemical service to provide appropriate compatibility and long-term operational reliability.

Safety & Chemical Compatibility
Chemical metering systems must be engineered according to the characteristics and hazards of the chemical being handled.
Chemical compatibility should be evaluated for pumps, seals, diaphragms, valves, piping, tanks, fittings and instrumentation. Where hazardous, corrosive, toxic, flammable or otherwise aggressive chemicals are involved, the system should incorporate appropriate containment, ventilation, pressure relief, isolation, emergency shutdown and personnel protection measures.
Final equipment selection and operating parameters should be confirmed against the project-specific chemical composition, concentration, pressure, temperature, flow rate and applicable safety requirements.
