The 2500 LPH Rotameter (1" size) is a precision flow measurement instrument designed for monitoring water flow in treatment systems. It features a clear, durable acrylic or glass body with a calibrated scale for accurate real-time flow indication. Suitable for flow rates up to 2500 liters per hour, it ensures reliable performance in various industrial and water treatment applications. The rotameter operates on a variable area principle, providing visual flow measurement without external power. Easy to install and maintain, it offers excellent chemical resistance, ensuring long service life and efficient water process control. Ideal for online flow monitoring.
The Rotameter 2500 LPH Online 1" is a precision flow measuring device designed to accurately monitor and control the flow rate of water and other compatible fluids in water treatment systems. With a capacity of 2500 liters per hour (LPH) and a 1-inch connection size, it is ideal for medium-scale applications, including filtration units, reverse osmosis (RO) plants, softeners, and industrial water treatment processes.
This rotameter operates on the variable area principle, where a float moves inside a tapered, transparent tube in response to the flow rate. The flow is indicated directly on the calibrated scale, allowing for easy visual monitoring. Constructed from durable materials such as acrylic, glass, or polycarbonate with SS-316 or PVC end fittings, it ensures long service life, chemical resistance, and corrosion protection, even under continuous operation.
Designed for online installation, it can be mounted directly onto pipelines without interrupting system flow, ensuring real-time measurement and process efficiency. The device offers low pressure drop, easy installation, and minimal maintenance, making it a reliable and cost-effective choice for operators.
Commonly used in industrial water treatment plants, effluent treatment plants (ETP), sewage treatment plants (STP), and process industries, the Rotameter 2500 LPH 1" provides dependable performance, high accuracy, and clear readability. Its robust design, simplicity, and accuracy make it an essential instrument for ensuring optimal water flow management and system performance in water treatment operations.
