A flow sensor is a device that measures the rate or volume of fluid flowing through a pipe or conduit. It is commonly used in various applications, including industrial process control, water management, and medical equipment. In this article, we will explore what a flow sensor is, the problems it solves, applications that use it, technical data, and the main manufacturers.
What is a Flow Sensor?
A flow sensor is an electronic device that measures the rate or volume of fluid flowing through a pipe or conduit. It typically consists of a flowing body with an inlet and outlet, a sensing element such as a turbine or paddle wheel, and an electronic circuit that processes the signal from the sensing element. The sensing element rotates as the fluid flows through it, generating a signal that is proportional to the flow rate. This signal can be used to control the fluid flow or measure the amount of fluid that has passed through the sensor.
Problems Solved by Flow Sensors:
Flow sensors solve a range of problems in various industries. In industrial process control, flow sensors are used to monitor the flow rate of fluids such as gases, liquids, and slurries, ensuring that production processes operate at optimal levels. In water management, flow sensors are used to measure the flow of water in pipes, detect leaks and control water usage. In medical equipment, flow sensors are used to monitor the flow rate of gases and liquids, ensuring that patients receive the correct amount of fluids during treatments.
