Water Flow Sensor (Sea) YF-DN40 Flowmeter G11/2 5-150L/min 5-24V
The YF-DN40 1.5-inch water flow sensor is built for industrial use, featuring a durable plastic body, a water rotor, and a hall-effect sensor. As water flows through the rotor, the flow rate alters the rotor’s speed, generating pulse signals that are detected by the hall-effect sensor. The output of the sensor is directly proportional to the flow rate, with a higher number of pulses corresponding to increased water flow.
Dn40 Sensor – Features:
- Accuracy: ±2% inline for flow rates ranging from 1 to 120L/min.
- Flow Pulse Characteristics: F = (0.45 * Q), where Q represents the flow rate in L/min.
- Temperature Performance:
- Low-Temperature Test: Accuracy within ±5% after 72h at -20°C followed by 1h at room temperature.
- High-Temperature Test: Accuracy within ±5% after 72h at 85°C followed by 1h at room temperature.
- Flow Rate: 5~150L/min
- Connection: G11/2 (1.5-inch) DN40
- Material: Plastic Hall Turbine
- Power Supply: 5-24V
- Switch Valve Control: Enables control over liquid flow through the sensor.
This water flow sensor provides reliable and accurate measurement of flow rates in industrial settings, ensuring precise monitoring and control over liquid flows. With its robust construction and versatile features, it’s suitable for various applications requiring flow measurement and control.
