Gear Flow Sensor | RS485 Digital Output | For Diesel, Oil & Water

This micro oval gear flow meter is a positive displacement flow sensor built for accurately measuring low-volume liquid flow. It works by using two rotating oval gears to measure a precise volume of fluid with each rotation, making it a very reliable way to track usage. Features and Benefits - Oval gear design - Measures true volume, so its accuracy isn't affected by changes in fluid viscosity or flow rate. - RS485 digital output - Provides a clean, interference-resistant signal for PLCs and data logging systems. - Aluminum and stainless steel parts - It's compatible with a range of fluids, including diesel, oils, and some chemicals. - Measures low flow rates - It can accurately track volumes down to 12 liters per hour, making it good for detailed monitoring. Applications - On small engines or test benches to monitor exact fuel consumption. - In automated systems for precise chemical dosing or additive mixing. - For tracking oil and lubricant dispensing in industrial machinery. Key Functions A flow meter measures the rate of flow of a fluid, such as a liquid or gas, through a pipe or conduit. This particular Gear Flow Sensor is designed for flow control applications. It provides an electronic RS485 digital output, enabling precise monitoring and control of fluid movement. The sensor is compatible with various fluids including diesel, gasolines, urea, and water, making it versatile for different industrial and commercial uses where accurate flow measurement is critical. Common Types of Flow Meters Flow meters are essential tools for accurately measuring the movement of liquids and gases. They come in various designs, each suited to different applications and fluid types. This product, an Oval Gear Flowm, uses a positive displacement method. Other common types include ultrasonic, electromagnetic, and vortex flow meters. While a peak expiratory flow meter is used in medical settings to measure airflow from the lungs, industrial flow meters like this one are used for process control and monitoring in pipelines. Key Types & How They Work Flow meters operate on various principles to determine fluid velocity or volume. For instance, the Gear Flow Sensor described here is an Oval Gear Flowm, which falls under the positive displacement category. These meters work by trapping and displacing a known volume of fluid with each rotation of their gears, directly measuring the volume passing through. This method provides high accuracy, especially for viscous fluids. Other types include turbine meters, which measure flow by detecting the rotational speed of a turbine within the flow path. Velocity-Based Meters Velocity-based flow meters calculate the flow rate by measuring the speed at which a fluid moves through a pipe. These meters infer the volume by knowing the pipe's cross-sectional area and the fluid's velocity. Examples include ultrasonic flow meters, which use sound waves, and vortex flow meters, which detect vortices created by an obstruction in the flow. This Gear Flow Sensor, however, is an Oval Gear Flowm, which directly measures volume rather than relying on velocity calculations. Differential Pressure (DP) Meters Differential pressure (DP) meters measure flow by creating a pressure drop across an obstruction in the flow path. Devices like orifice plates, venturi tubes, or nozzles are used to create this pressure difference. The flow rate is then calculated based on the measured pressure differential and the known characteristics of the obstruction. While effective for a wide range of fluids, this Gear Flow Sensor operates on an oval gear principle, directly measuring fluid volume rather than relying on differential pressure.
