Description

Liquid flow meter 1-30L per minute

Liquid flow sensor made of high-grade PPS plastic that is chemically and mechanically resistant is used to control external devices. Responds to even a small flow by generating a high-resolution voltage signal to the controller.

Example of flowmeter design here.

Product features

• Very easy installation
• Wide range of usability
• Simple, low-failure design
• Pulse output

Technical data

• power supply 3,5 – 24 VDC
• working pressure maximum 17.5 bar
• maximum operating current 10mA
• medium temperature -20 to +90 C
• connections 1/2 inch (external diameter of the thread 20mm)
• flow rate 1-30 liters/minute
• resolution F=(7.8*Q) ±10% Q=L/MIN
• number of pulses per liter of liquid : 468 +- 10%

For a flow rate of 1 liter/minute, for example, the sensor will generate a rectangular signal with a filling of about 50% and a frequency of 7.8 Hz (+-10%).

Similarly, for a flow of 10 liters/minute, it will be 78 Hz (+-10%)
