YF-DN50-S Stainless Steel Liquid Flow Sensor - 2 inch Diameter

The YF-DN50-S is a high-precision 2-inch liquid flow sensor made from durable 304 stainless steel, designed for measuring water flow in industrial and commercial applications.

It operates at DC 5V (with a working voltage range of DC 3.5–24V) and supports a flow rate from 10 to 200 liters per minute with an accuracy of ±5%. The inlet diameter is 46.5mm, outlet is 44mm, and outer diameter is 59mm, with a thread length of 20mm.

It can withstand water pressure up to 1.75 MPa and has an insulation resistance of over 100 MΩ. The sensor produces pulse signals at a rate of approximately 12 pulses per liter with a duty cycle of 50% ±10% and a high-level output above DC 4.7V.

It passes both high and low-temperature tests, maintaining ±5% accuracy after exposure to -20°C and 85°C for 72 hours.
