The helical rotor flow meter works by moving a fixed volume of fluid through its rotor mechanism. The helical rotors, positioned inside the meter, create a swirling effect as the fluid enters and is measured. As the fluid flows, the movement of the rotors generates a constant torque, allowing for accurate measurement of the volume displacement. This ensures precise flow rates for liquids, making it ideal for a variety of applications. Its positive rotor displacement capabilities make it a good choice for industries seeking reliable and accurate flow measurement solutions.
Manufactured by Broil Sensotek Industries, this flow meter features an integrated display for easy reading and monitoring. It offers multiple output options, including RS 485, HART, 4-20 mA, and pulse output. This versatility allows for seamless integration into existing systems while accommodating a variety of industrial communication protocols.

The pulse output function of the helical rotor flow sensor enhances its functionality by providing digital signals related to volumetric flow rate. Each pulse represents a specific volume of fluid, allowing users to easily monitor and control flow rates in real time. This feature is particularly useful in industrial settings, where accurate flow measurement is essential for process control.
