Flow Indicators

RHFS provides a comprehensive selection of visual and rotor flow indicators designed for monitoring liquid flow. These visual indicators are available in various sizes, ranging from ¼ inch NPT to 1 inch NPT, and can accommodate flow rates of up to 20 gallons per minute (GPM), making them suitable for a wide range of applications. Additionally, we offer sight glass indicators, which are available in both single and double-wall construction to ensure enhanced safety and durability. These sight glasses come in sizes from 1/2 inch to 8 inches and are crafted from a variety of materials, each selected to withstand and handle aggressive and corrosive fluids effectively. Our products are designed to provide accurate and reliable flow monitoring, ensuring optimal performance and safety in industrial processes. They deliver immediate visual confirmation of flow presence and direction, helping operators quickly verify system status during start-up, commissioning, and routine inspections. Options for body, lens, and seal materials allow customization to specific media and temperature or pressure requirements, while multiple end-connection choices support straightforward installation and retrofits. Built for demanding environments, each unit is engineered for long service life and low maintenance, helping reduce downtime and total cost of ownership. RHFS application specialists are available to assist with sizing and material selection to ensure you get the right indicator for your process.
