Product Overview	The Portable Livestock Environmental Airflow Meter is a handheld measuring instrument designed for on-site assessment of air movement and ventilation performance in commercial poultry houses, pig farms, cattle barns, calf facilities and other agricultural buildings. The compact meter allows farm managers, livestock technicians, ventilation engineers and project contractors to check air velocity at animal level, air inlets, fan discharge areas, ventilation ducts and other critical points throughout a livestock building. Depending on the selected configuration, the instrument can combine air velocity measurement with temperature, relative humidity and other environmental functions, providing practical field data for ventilation adjustment, climate assessment and routine livestock-house inspection. Its portable design makes it suitable for commissioning new farm projects, comparing different ventilation zones and troubleshooting airflow problems without installing permanent monitoring equipment.
Key Features	Portable Airflow Measurement: Handheld construction allows fast movement between barns, rooms and multiple measurement positions. Animal-Level Air Speed Testing: Suitable for checking drafts, stagnant zones and actual air movement around pigs, poultry, calves and cattle.

Multiple Environmental Functions: Air temperature, relative humidity and additional environmental measurements are available according to selected configuration. Clear Digital Display: Measurement results can be viewed directly during farm inspections and ventilation commissioning. Data Functions: Minimum, maximum, average, hold or recording functions are available according to model configuration. Farm-Friendly Construction: Compact housing is suitable for routine agricultural inspection, transport between sites and field engineering work. Flexible Project Selection: Measurement range, sensor functions and accessories can be selected according to project requirements.
Structural Components	Air Velocity Sensor: A vane, impeller or other suitable sensing element measures local air movement at the inspection point. Handheld Meter Body: Houses the electronics, operating controls, display and power supply in a compact portable enclosure. Digital Display: Shows airflow measurements and available environmental parameters according to the selected instrument configuration. Control Keypad: Provides access to measurement units, hold, minimum, maximum, average and other available functions. Temperature Sensor: Available for simultaneous environmental temperature measurement depending on configuration. Humidity Sensor: Available on selected multifunction environmental meter versions. Protective Sensor Structure: Helps protect the airflow sensing element during normal farm use and transportation. Optional Carrying Accessories: Carrying case, lanyard, tripod, extension fixture or other accessories are available upon request.
Working Principle / Structural Principle	When the meter is positioned in the airflow, moving air passes through or across the sensing element. The sensor converts the airflow response into an electrical signal, and the internal electronics calculate the corresponding air velocity value for display. For vane-type configurations, the airflow rotates a low-friction impeller and the instrument converts rotational speed into an air velocity reading. Selected multifunction meters can combine airflow information with temperature, humidity and other environmental measurements. For livestock-house inspections, measurements can be taken at several representative positions rather than relying on a single reading. Comparing animal-level areas, air inlets, fan zones and different sections of the building helps operators understand how effectively ventilation air is distributed. When volumetric airflow calculation is available, duct dimensions or measurement area can be entered according to the selected meter configuration and operating procedure.

Installation & Maintenance	The portable airflow meter normally requires no permanent installation. Before measurement, inspect the airflow sensor for dirt, physical damage or obstruction and confirm that sufficient battery power is available. Allow the livestock ventilation system to reach stable operating conditions before taking comparative readings. Hold the meter at the required measurement position and maintain consistent sensor orientation when comparing multiple points. Animal-level measurements should be taken at representative locations throughout the occupied zone. Additional readings near air inlets, circulation fans and exhaust areas can help identify differences in airflow distribution. Avoid blocking the sensor with the operator's body, clothing or nearby equipment. Measurements immediately behind structural columns, feeders or partitions may be affected by local turbulence. After use in dusty livestock buildings, remove loose dust and debris from the sensor according to the instrument maintenance instructions. Do not expose sensitive electronic components to aggressive washing or disinfectant solutions unless the selected configuration is specifically designed for such conditions. Store the meter in a dry protective case when not in use. Periodic functional inspection and calibration are recommended according to measurement frequency and project quality requirements.
Project Cases	Commercial Broiler House: Technicians can take measurements at multiple bird-level positions to compare air movement throughout a tunnel-ventilated poultry building. Pig Nursery Ventilation Check: Air speed measurements can help identify excessive drafts near inlets and areas with insufficient air movement within piglet pens. Fan Commissioning Project: Measurements near selected ventilation fans can support field comparison before and after cleaning, maintenance or system adjustment. Air Inlet Adjustment: Engineers can compare inlet air velocity at multiple openings when commissioning negative-pressure livestock ventilation systems. New Livestock Building Handover: Portable measurements can support ventilation inspection during commissioning of steel structure poultry, pig and cattle buildings. Seasonal Farm Inspection: The same portable meter can be used across multiple barns to compare airflow conditions under winter minimum ventilation and summer high-ventilation operation.
