These indicators are capable of handling a wide range of liquids and gases, including safe gas.
Their comprehensive range of flow indicators is designed to cater to any flow monitoring application, be it simple or complex.
What is a flow rate indicator?
A flow rate indicator is a device designed to measure and display the rate at which a fluid (liquid or gas) is flowing through a system. It provides real-time information about the quantity of fluid passing through a particular point, often expressed in units like gallons per minute (GPM) or cubic meters per hour (m³/h). Flow rate indicators are commonly used in various industries, including manufacturing, process control, and fluid systems, to monitor and manage the flow of substances within a specified range.
How flow rate indicator works?
A flow rate indicator works by having something in the flow of the liquid or gas that reacts to how fast the fluid is moving. For example, a spinning wheel or paddle may turn faster when more fluid is flowing. This reaction is then turned into a display, like a number on a screen or a position on a gauge, showing how quickly the fluid is moving through the system. Calibration ensures that the displayed information is accurate.

Paddle Flow Switch
The FS 20 and FS 25 New-Flow paddle switch flowmeter is a type of flowmeter manufactured by New-Flow, a company known for its instrumentation and flow measurement devices.
The FS 20 and FS 25 model specifically may have certain specifications or features unique to it, such as flow range, operating temperature range, pressure ratings, and the types of fluids it can measure.
What is a flow switch?
Paddle switches are commonly used in various industries and
applications, including industrial machinery, woodworking tools, and power
tools. They are designed to provide a convenient and safe way to turn equipment
on and off, often featuring a large, easily accessible paddle that can be
pressed or toggled with minimal effort.
How does flow switch works?
A paddle switch flowmeter typically consists of a housing with a flow channel through which the fluid flows. Inside the flow channel, there is a paddle that is free to move with the fluid flow. As the fluid flow rate increases, the paddle is pushed further by the flow. The movement of the paddle triggers a switch mechanism, which can be used to signal flow conditions, such as detecting flow presence, flow rate changes, or reaching a certain flow rate threshold.
