MEMS Flow Sensor FR03
Summary:
The FR03 flow sensor is developed for the upgrade of the original F1013 product. It uses the MEMS thermal principle to monitor the flow of the pipeline gas medium. This product adopts a low pressure loss design and is widely used in various gas measurement.
Feature:
* High sensitivity
* Very low starting flow
* High precision
* High measurement repeatability
* Low pressure loss
* Modular Design
APPLICATION
Ventilator and Anesthesia Machine
The respiratory system is a very important life support system for the human body. The gas flow sensor, which is a key component for monitoring airflow velocity parameters, has been widely used in ventilators and plays an important role. From hospital bed oxygen supply, floor pipeline oxygen supply to oxygen generators, ventilators, anesthesia machines and other medical equipment needs the support of flow sensors.
The World Health Organization's "Indoor Air Pollution and Health" pointed out that the current level of indoor air pollution is 5-10 times higher than outdoor pollution, and 4% of global diseases are related to indoor air quality, and about 2 million people die prematurely each year from diseases caused by indoor air pollution.
