Abstract:
Sensor offsets for an air filter monitor installed in an HVAC system may be determined by measuring a sensor offset differential pressure value across an air filter when substantially no air flow exists through the air filter. The sensor offset differential pressure value obtained at or near zero flow may represent the sensor offset for the air filter monitor. The sensor offset differential pressure value may be used to compensate an un-compensated differential pressure value obtained during flow conditions.
