Here's a breakdown of its key features and specifications:

Pipe Size: The sensor is designed for use with pipes or conduits that have a nominal size of DN40, which corresponds to a pipe diameter of approximately 40 millimeters (1.5 inches).

Flow Measurement Range: The sensor is capable of measuring water flow rates within a range of 5 to 150 liters per minute (L/min). This range specifies the minimum and maximum flow rates it can accurately measure.

Flow Sensing Method: The sensor uses a Hall effect sensor or Hall sensor technology to measure the flow of water. Hall effect sensors detect changes in magnetic fields caused by the movement of a magnet, which is typically incorporated into the sensor's design.

Output Signal: The sensor typically provides an electrical signal as output, which can be analog (e.g., voltage or current) or digital (e.g., pulse output). This signal can be interfaced with monitoring systems, controllers, or data loggers to record and analyze flow data.

Accuracy and Calibration: The accuracy of the flow sensor is an important consideration, and calibration may be necessary to ensure precise measurements. The accuracy of this particular sensor may vary depending on the specific model and manufacturer.

Materials and Compatibility: Flow sensors are typically constructed from materials compatible with water, such as stainless steel, brass, or plastic, to prevent corrosion. Compatibility with the fluid being measured is crucial to ensure the sensor's longevity.

Installation: Proper installation is essential to ensure accurate flow measurements. Follow the manufacturer's guidelines for installation, including proper orientation and positioning within the pipe or conduit.
