Run at full speed
Monnit’s Enterprise Air Velocity/Speed Wireless Sensor helps facility managers and maintenance techs gauge and track HVAC performance by measuring system airflow and building/room pressure.
If air velocity (speed) deviates from user-set limits, an alert is issued instantly via text, email, or call. Early notifications allow HVAC contractors or maintenance techs to prevent failure (or predict and shorten downtime). Collected data also enables facility maintenance professionals to maintain comfort and proper ventilation, as well as track air volume filter status.
This air velocity/speed sensor measures the pressure difference between its two ports, accounts for ambient temperature and altitude, and determines system airflow speed in meters per second (m/s). The sensor is calibrated, temperature compensated, and has a -50 m/s to +50 m/s measurement range.
Maintain comfort and proper ventilation
The Wireless Air Velocity Sensor measures the pressure difference between two input ports, the temperature, and altitude determines the speed at which the air is moving in a system and transmits the measurement to iMonnit. When viewing the sensor from the top, the right inlet port is the positive or high side pressure input. When the pressure on this port is greater than the left port the sensor produces a negative pressure reading. When the pressure is greater on the left port the sensor produces a positive pressure reading. Combined with the temperature and the altitude, the sensor determines at what rate the air is flowing in a system.
This sensor come standard with two replaceable AA batteries. The typical battery life is approximately 10 years.
