6The Phoenix Controls Legacy We Dont Measure
Flow
- Flow Metering vs. Flow Measuring
- Flow measuring has a limited range of
operation. - Flow measuring requires long, straight duct runs
(not available in most applications). - Flow measuring is prone to inaccuracies due to
the caustic nature of laboratory exhaust air - Flow measuring has inherent time lags due to
airflow dynamics - Flow measuring requires periodic maintenance
7Factory Calibration
- Drastically Reduces Commissioning Time
- Can be pre-commissioned before supply and exhaust
air is connected - No sensors to set up or flows to adjust
- No routine maintenance requirements
