Liquid Flow Meter - Plastic NPS Threaded

Now available from PMD Way are these great value plastic liquid flow meters. They use a hall effect sensor to output a pulse every time the internal sensor rotates.

Your microcontroller (etc) then counts the pulses to determine flow rate. 1 litre of water is 450 pulses. 

Use the options menu to select your required diameter.

Specifications:

• Operating voltage: 5V DC
• Operating current: 10 mA (5V DC)
• Full operating voltage range:5~18V DC
• Operating temperature range: 0~80 degrees C (no ice)
• Operating humidity range: 35% ~ 90% RH (frost free state)
• Maximum water pressure: 1.75Mpa
• Measuring distance:60 (m3/h)
• Flow range:1~30L/min
• External and Internal Thread Diameter: G1/2"

Wiring:

• Red - power
