Brass Hall effect water flow sensor for 1/2, 3/4, and 1 inch connections.

The water flow sensor is a reliable device for measuring the flow rate of water in water heaters, vending machines, and other systems. The brass water flow sensor consists of a sturdy housing, a rotor mechanism, and a Hall effect sensor, which accurately detects changes in flow and transmits a signal to the controller. It is ideal for installation at the water inlet where it is necessary to monitor and regulate the water flow.

Brass water flow sensor - key features

• Compact design — The compact and lightweight housing allows for easy installation of the device in confined spaces without extra effort.
• Durable impeller mechanism — The impeller with embedded stainless steel balls ensures durability and resistance to wear.
• Leak-proof design — The sealing ring with upper and lower force structures completely protects against leaks.
• Protected Hall sensor — The original imported component is filled with sealing adhesive, so water cannot penetrate and the sensor does not age.
• Wide application — Suitable for use in water heaters, drinking fountains, water vending machines, and other systems.
• Accurate signal transmission — The pulse output allows the controller to accurately determine and adjust the water flow rate.

This device is recommended for both residential and commercial systems where reliable flow measurement is important.

Buyer questions

Question: What water pressure is this sensor resistant to?
This device is resistant to water pressure up to 1.75 MPa. The leakage test is performed by applying 1.7 MPa of pressure for one minute to check for any leakage or deformation.

Question: How do I correctly connect the wires to the sensor?
The red wire is connected to the positive terminal, the yellow wire is the signal output line, and the black wire is connected to the negative terminal. It is essential to follow this wiring diagram.

Question: What is the maximum temperature this device can withstand?
This device is designed for use with materials that have a temperature not exceeding 120°C. Higher temperatures may damage the seal and affect the sensor's performance.

The brass water flow sensor is a reliable and accurate choice for monitoring water systems. It is suitable for heaters, vending machines, and other devices where durability and accuracy are important.
