HVAC Fan Tracking for Building Pressurization
HVAC fan tracking requires precise measurement of the complete airflow system, including supply air, return air, outside air, and relief air; all of which must be maintained in balance to control building pressurization.
Air Monitor offers both thermal and differential pressure HVAC fan tracking equipment to keep your building or space pressurized and maintain the proper air balance.
Air Monitor’s airflow measurement solutions for HVAC fan tracking help ensure that pressure is accurately maintained throughout modern industrial, commercial, and residential buildings.
Air Monitor Solutions Can Help You
Control Ventilation Rates
Measure the air volume that flows through the system, enabling demand-controlled ventilation and aiding with the positioning of ventilation dampers, which control airflow.Maintain Steady Airflow and Pressurization
Measure channel pressure changes within an HVAC system’s air ducts, which can trigger adjustments in fan power to ensure steady airflow.Ensure Healthy Air Quality and Energy Efficiency
Monitor the condition of air filters within HVAC systems, to determine optimum filter replacement times and reduce heating and cooling expenses.ELECTRA-flo/FI Thermal Dispersion Fan Inlet Probe Array
The ELECTRA-flo/FI Thermal Fan Inlet Airflow Probe utilizes dual point thermal dispersion technology sensors installed in the fan’s inlet bell mouth at the throat. Aerodynamic sensor apertures, assisted by the air processing effect of the nozzle-shaped fan inlet, provide accurate measurement for most fan types.
ELECTRA-flo sensors are factory calibrated to NIST traceable standards, and each fan inlet assembly comes complete with an ELECTRA-flo transmitter for local data display, performing configuration and calibration, and providing analog outputs of airflow and temperature.
VELTRON III Transmitter
The VELTRON III Pressure & Airflow Transmitter is a multi-functional, dual-channel transmitter specifically designed for HVAC airflow measurement applications. The flexible design can be combined with any differential or static pressure measurement probes, stations, piezo rings, or traverse-style fan inlet probes.
The VELTRON III uses an application-specific tailored array of precision transducers to provide the best turndown and accuracy needed for today’s high-performance buildings. The unique transducer design eliminates the need for periodic re-zeroing common with traditional differential pressure-based technologies.
Applications include dual-channel or single-channel systems for building airflow measurement for single or dual-fan systems and fan discharge plenum pressure.
VOLU-probe/FI Pitot Fan Inlet Airflow Traverse Station
The VOLU-probe/FI combines the air processing effect of the nozzle-shaped fan inlet bellmouth with a unique Fechheimer Pitot derivative of the multi-point, self-averaging Pitot to accurately measure inlet velocity pressure (and calculable air volume) for most types of fans.
The VOLU-probe/FI probes are mounted directly in the inlet bellmouth at the throat (minimum diameter). When mounted per factory recommendations, the measurement capability of the VOLU-probe/FI is not impaired by inlet screens, fan shafts, drive pulleys, guards, adjustable blade pitch (vane-axial fans), etc., downstream of the probe location.
DPT-100
The DPT-100 Pressure & Flow Transmitter is designed to measure differential pressure and calculate airflow with high precision, making it ideal for a wide range of HVAC applications. It features a temperature-compensated piezoresistive measuring element that ensures excellent long-term stability. Even the smallest pressure differences are accurately detected, providing outstanding reliability and measurement accuracy.
The DPT-100 offers freely adjustable measuring ranges and can be easily configured via integrated buttons and the display interface.
Applications include Supply Ducted Air Flow, Return Ducted Air Flow, Single Fan Systems, Positive and Negative Space Pressurization, Fan Discharge Plenum Pressure, Room Pressure Average Sensing, and Large Duct Pressure.
