Rate Flow Sensor | Digital Monitoring Detector | Brass Hall Effect Switch

This brass water flow sensor measures how fast liquid moves through a pipe. Its internal Hall effect sensor sends a digital pulse for each turbine turn, letting you track flow precisely. The solid brass body handles higher pressures and temperatures better than plastic options. Features and Benefits - All-brass build - Resists corrosion and takes pressures up to 1.75 MPa. This makes it good for industrial use or inside a water heater. - Hall effect sensing - Gives a steady pulse output signal. It's simple to read with microcontrollers like an Arduino for exact digital tracking. - Built-in temperature sensor - This model has an NTC thermistor to sense liquid temperature. You get two data points from one device. - Standard G1/2 threading - Connects easily to common pipes and fittings. This simplifies setup for different water control jobs. Applications - Water heater setups - Checks flow to make sure the heating element only turns on when water is running. This makes it more efficient and safer. - DIY electronics projects - Use this pulse output brass water flow sensor to build your own water use trackers or automatic watering systems. - Liquid dispensing machines - Accurately measures how much liquid is dispensed in drink machines or chemical mixing units. Key Functions This Digital Monitoring Detector is designed for liquid flow rate monitoring. Its primary function is to provide a digital output, indicating the rate at which liquid is flowing through it. The Brass Hall Effect Switch integrates a PCB, making it a self-contained unit for sensing liquid movement. As a flow sensor, its role is crucial in systems requiring precise measurement and control of fluid dynamics, offering reliable digital feedback on flow conditions. Common Types of Flow Meters Flow meters are devices used to measure the linear or non-linear mass or volumetric flow rate of a liquid or gas. This particular product is a Flow Sensor, specifically a Hall Effect type. Other common types of flow meters include ultrasonic, electromagnetic, and thermal mass flow meters, each suited for different applications and fluid types. Understanding the specific function, such as liquid flow rate monitoring, helps in selecting the appropriate meter for a given task. Key Types & How They Work This Rate Flow Sensor operates on the Hall Effect principle, providing a digital output. A Hall Effect sensor detects changes in a magnetic field. In a flow sensor, this often involves a turbine or paddle wheel that rotates with the liquid flow, generating a magnetic field that the Hall Effect sensor then reads. The frequency of the digital signal directly correlates to the flow rate. For example, a peak expiratory flow meter, while not directly related to this product, measures the maximum speed of exhalation, indicating lung function, and works on different principles. Velocity-Based Meters Velocity-based meters, like this Hall Effect Switch, determine flow by measuring the speed of the fluid. In this product, the Hall Effect sensor detects the rotation caused by liquid flow, which is then translated into a digital output representing the velocity. Other velocity-based meters include turbine meters and vortex meters. They are often chosen for their accuracy and ability to provide real-time flow data for liquid flow rate monitoring applications. Differential Pressure (DP) Meters Differential pressure (DP) meters measure flow by creating a pressure drop across an obstruction in the flow path. This product is not a DP meter; it is a Hall Effect Flow Sensor. Common DP meters include orifice plates, venturi tubes, and flow nozzles. The pressure difference is then used to calculate the flow rate. Unlike this Digital Monitoring Detector, which provides a direct digital output from a Hall Effect sensor, DP meters require additional instrumentation to convert pressure readings into flow data.
