Heating, ventilation, and air conditioning (HVAC) is the technology of indoor and vehicular environmental comfort. Its goal is to provide thermal comfort and acceptable indoor air quality.
HVAC is an important part of residential structures such as single family homes, apartment buildings, hotels and senior living facilities, medium to large industrial and office buildings such as skyscrapers and hospitals, vehicles such as cars, trains, airplanes, ships and submarines, and in marine environments, where safe and healthy building conditions are regulated with respect to temperature and humidity, using fresh air from outdoors.
HAVC control and monitor is a very important part to reduce the harmless to the nature. And Maximize Resource Savings. A good and useful HACV intelligent monitoring system can save 20% ~ 30% of power loss. That's why ultrasonic flow meters / BTU meters have become the most wide use equipment in HVAC.
Ultrasonic flow meter FT201 of FlowT is designed only for water and could be widely used in HVAC. FT201 totalizes flow daily, monthly and yearly. Parallel operation of positive, negative and net flow totalizes with scale factor and BTU Capacity. While the output of totalize pulse and frequency output are transmitted via relay and open collector.
