HVAC & Gas Treatment Instrumentation Solutions
HVAC, heating, cooling and gas-treatment systems depend on stable pressure, differential pressure, temperature and flow measurement to deliver efficiency, comfort and safe equipment operation.
Key Application Areas
- Heating and chilled-water circuits
- Air-handling units and ventilation ducts
- Industrial boiler and heat-transfer stations
- Gas conditioning and pressure regulation
- Filters, fans, pumps and compressors
Critical Measurement Points and Recommended Instruments
| Measurement | Recommended Instrument Types | Typical Locations |
|---|---|---|
| Differential pressure | Low-pressure and differential gauges/switches | Filters, fans and air ducts |
| Pressure | Bourdon gauges, transmitters and switches | Pumps, boilers and gas trains |
| Temperature | Bimetal, gas-actuated and RTD instruments | Supply/return lines and heat exchangers |
| Flow | Magnetic, ultrasonic and thermal flowmeters | Water, air and utility gas circuits |
Engineering and Selection Priorities
- Low differential-pressure accuracy
- Condensation and outdoor installation
- Energy metering and system balancing
- Reliable switching and local indication
