Water Flow Sensor G1/2
If you are looking for a way to control the flow of liquid in your system, you need to know its flow rate. With this sensor, the reading flow rate would be convenient as this sensor could fit into G1/2 pipes.
This sensor could sense the flow rate from 1L/min to 30L/min. On the inside, it has a magnetic core and a hall-sensor, which triggered outputs an analog voltage.
It can work with liquid temperatures less than 120°C, and humidity of 35% to 90% RH. The water pressure it can handle is up to 2MPa. It can be stored in places with -25°C to 80°C, with a humidity of 25% to 95% RH.
It can be operated with voltages from 5V to 24V, with a max current of 15mA. It also has a load capacity of less than 10mA.
Here is a simple calculation: Water Flow = Pulse Frequency / 7.5. So, if you got 90 frequency reading, 90/7.5 = 12 (L/min)
