Where inside the mechanical ventilation system of a modern tunnel-ventilated closed layer house should the static pressure sensors be positioned?

In negative pressure tunnel-ventilated houses, static pressure measures the resistance to air entering the house. To obtain an accurate and representative reading, the pressure sensor must be placed along the longitudinal sidewall, roughly 1/3 to 1/2 of the distance down the house (30-40 meters from the air inlets), mounted at the height of the bird cages (approximately 1.5 to 1.8 meters high). Placing the sensor too close to the exhaust fans or too close to the inlet pads will yield false extreme readings, causing the environmental controller to open or close inlets incorrectly. This leads to dead air zones or excessive air velocity. Engineers can study mechanical airflow design in the Poultry Encyclopedia, source precision digital pressure gauges on Poultry Plaza, monitor the financial impact of environmental control on egg rates at Poultry Rates, and sell fully automated layer farms on Murghi Mandi.
