• Define and optimize:
  • Sensor accuracy, repeatability, and response time
  • Sensor placement within CDU loops for best performance
  • Measurement philosophy and redundancy (dual sensors, voting logic)
• Prepare:
  • Instrument datasheets and technical specifications
  • Vendor evaluations and technical comparisons
• Ensure:
  • Compatibility with control systems (4–20 mA, 0–10V, digital protocols)
  • Suitability for operating conditions (glycol systems, condensation, IP ratings)

 

2. Valves & Flow Control Systems

• Selection and sizing of valves:
  • PIBCV (Pressure Independent Balancing Control Valves)
  • Control valves and actuators
  • Isolation and balancing valves
• Define valve control strategies:
  • Flow balancing and optimization
  • Integration with VFD-driven pump systems
• Work closely with mechanical teams for hydronic system optimization

 

3. System Integration & Controls Interface

• Support configuration of communication protocols:
  • Modbus RTU/TCP
  • BACnet
  • CAN / Ethernet
• Collaborate with control engineers for:
  • Control logic validation
  • Signal mapping and I/O definition

 

4. Testing, Commissioning & Validation

• Define and execute:
  • Instrument validation and calibration procedures
  • FAT (Factory Acceptance Test) and SAT (Site Acceptance Test)
• Support:
  • System commissioning and troubleshooting
  • Root cause analysis of sensor or control issues
• Ensure long-term reliability of instrumentation systems

 

5. Documentation & Standards

• Develop and maintain:
  • Instrument datasheets and selection reports
  • Loop diagrams and I/O lists
  • Input to control philosophy and FDS
  • Support P&IDs in coordination with mechanical teams
• Ensure compliance with:
  • ASHRAE guidelines
  • IEC / UL standards

 

Required Skills & Competencies

• Strong expertise in:
  • Sensor selection and instrumentation design
  • Valve selection and hydronic system understanding
• Good working knowledge of:
