7.3.3 Flow Sensors (1) Concept A flow sensor is a device that measures the flow rate (instantaneous flow), cumulative flow, or both of fluids (including liquids, gases, steam, etc.). It converts the flow information of the fluid into usable output signals (such as current, voltage, digital signals, etc.) for the display, recording, and control of … Read more
Selecting the appropriate temperature and humidity sensor for an incubator is a crucial step for successful hatching, directly affecting embryo development and hatchability. A good sensor should possess high precision, high stability, and good durability. Below, I will provide a comprehensive selection guide covering core parameters, the pros and cons of different types of sensors, … Read more
