A Rotameter 20000 LPH Online is a precision flow measuring device used in water treatment systems to monitor and control water flow rates up to 20,000 liters per hour. It operates on the variable area principle, where a float moves within a tapered tube according to the flow rate. The clear acrylic or glass body allows easy visual reading, and it can be installed directly in the pipeline for continuous, real-time flow monitoring. Ideal for industrial and water treatment applications, it ensures accurate flow measurement, efficient process control, and system optimization for reliable water management and performance.
The Rotameter 20000 LPH is a precision flow measuring instrument designed for accurate and continuous monitoring of water flow in online water treatment systems. Built with durable materials such as acrylic, glass, or stainless steel, this device ensures long-term reliability and resistance to corrosion and chemical exposure, making it ideal for industrial, municipal, and commercial applications.
Operating on the variable area principle, the rotameter consists of a tapered tube and a float. As water flows upward through the tube, the float rises to a point where the area between the float and tube wall allows the flow rate to stabilize. The position of the float directly indicates the flow rate on a calibrated scale, typically measured in liters per hour (LPH). With a capacity of up to 20,000 LPH, this rotameter supports medium to high flow rate applications, ensuring efficient monitoring of treatment plant operations.
The online rotameter is easy to install and maintain, with optional features such as flange or threaded connections and a clear, direct-reading scale for quick visual monitoring. It is suitable for use in reverse osmosis (RO) plants, effluent treatment plants (ETPs), cooling towers, and industrial water supply systems.
By providing precise real-time flow measurement, the Rotameter 20000 LPH enhances system performance, reduces wastage, and supports accurate process control—making it a vital component in any modern water treatment facility.
