Hydronic Manometers

Water-side performance directly affects air-side results. Hydronic manometers give facilities teams the differential pressure data needed to calculate flow, validate valve authority, and tune pumps and coils — key steps for reliable ventilation and comfort across public safety buildings.

Where They Help

• Dispatch and Command: Maintain stable cooling/heating for equipment rooms and occupied spaces.
• Detention and Housing: Support temperature stability in zones with variable occupancy.
• Labs and Training Centers: Verify coil performance for ventilation demands and comfort.
• Post-Event Recovery: Confirm restored water-side performance after outages or repairs.

Capabilities

• Differential Pressure Measurement: Quantify pressure across coils, strainers, and control valves.
• Flow Determination: Use valve charts or Cv/Kv values with measured ΔP to estimate flow.
• Temperature Considerations: Account for fluid temperature and glycol percentage where applicable.
• Data Logging: Record readings with time stamps to support maintenance and commissioning reports.

Field Tips

• Bleed Air: Purge air from hoses and ports for stable readings.
• Proper Connections: Use appropriate adapters to avoid leaks at test ports.
• Baseline and Trend: Capture pre- and post-adjustment values for validation.
• Pair With Air-Side Tools: Combine hydronic results with airflow and temperature data to close the loop.

Selection Guidance

• Pressure Range and Resolution: Choose instruments suited to expected ΔP across your components.
• Fluid Compatibility: Confirm hose and seal materials for water/glycol mixes.
• Accessories: Include hoses, probes, and quick-connects for common valve types.
• Durability: Field-ready housings and protective cases support frequent deployment.

A disciplined approach to hydronic measurement helps agencies reduce hot/cold calls, support energy goals, and improve occupant experience. By aligning water-side balancing with air-side verification, teams create a stable foundation for reliable HVAC performance across diverse public saf
