Liquid flow switch with a stainless steel flow body. OSMIUM Series flow switches are highly robust thermal flow switches with a precision engineered flow body to create a reliable, cost-effective flow monitoring solution that requires minimal set-up and is easy to install.
McMillan Flow Products introduces the OSMIUM Series, a highly robust thermal flow switch with a precision engineered flow body to create a reliable, cost-effective flow monitoring solution that requires minimal set-up and is easy to install.
Designed to achieve optimal flow conditions in a compact package, the OSMIUM thermal flow switch has options available to cover a wide range of flow rates and can be paired with an assortment of different process connections, providing flexibility for a variety of applications. The OSMIUM’s technology features microprocessor-based temperature compensation, ensuring reliable flow monitoring even in the presence of temperature fluctuation.
McMillan Flow Products offers a unique calibration service for this product to ensure exceptional performance and repeatability for each customer’s specific application.
The OSMIUM thermal flow switch provides a simple and efficient solution for customers in need of reliable and cost-effective flow monitoring for their non-viscous water-based liquids.
Flow bodies are designed to achieve optimal flow conditions in a compact package and are available aluminum (8721) or stainless-steel (8723) construction. Flow ranges as low as 150 – 1000 mL/min to as high as 1.2 – 50.0 L/min are supported.
Process connections are available in a wide variety of sizes and material construction. Range 1L | 10L | 20L units units come stock with 3/8” FNPT ports, and Range 50L units come stock with 3/4” FNPT ports. Consult the Product Configurator for more details.
The system achieves superior temperature compensation during the measuring cycle using a microcontroller. This ensures accurate correction of flow measurement even when liquid temperature changes occur.
This device utilizes a PNP open collector that is either normally open or normally closed. The normally open option enables a high-resistance state when flow is below the setpoint. The normally closed enables a high-resistance state when flow is above a setpoint.
Units come standard with a 4-Pin Micro DC connection. Optional mating cables with various lengths are available.
Our expert technicians can set up the device based on individual application parameters, including adjusting the flow range and setting the switch point to a desired rate. This service helps minimize installation and setup time, allowing for a more streamlined and efficient workflow. For optional custom calibration services, please contact the factory or an authorized representative for more information.
Optional steel mounting hardware is available. The mounting kit includes a fixed set screw that aligns with a socket feature on the device to insure optimum positioning.
An array of 8 LEDs is used to visually monitor general flow rate. A blinking setpoint LED function can be adjusted along the array to indicate when the device should switch.
