Similar products on the market are generally divided into velocity type and flow type. The product is a velocity type, using a heater and two thermopiles for measurement. It is suitable for measuring air/gas velocity in open environments. Flow-type products are primarily used to measure the flow of liquid or gas through a pipeline, typically expressed in volume or mass.
The product offers two output modes:
The product continuously senses after being powered on and only outputs data upon receiving a command.
