Description
Rotameter For Water – 0 to 200 LPH Water Flow Meter with Inlet Valve, 1/4″ BSP (M) Connection
Overview
-
The “Ji” Japsin Instrumentation Acrylic Tube Rotameter is a compact and reliable flow measurement device engineered specifically for measuring water flow in various industrial, commercial, and laboratory settings. With a flow range of 0 to 200 LPH (Liters Per Hour), this model is ideal for applications that require precision, simplicity, and durability. Constructed from high-grade acrylic, the rotameter for water provides excellent transparency and strength, allowing users to clearly observe the float’s movement and accurately read the flow rate.
Designed for vertical panel mounting, this rotameter for water features 1/4” BSP male threaded connections at the side top and bottom, allowing for easy integration into existing piping systems. It also includes a built-in inlet control valve to regulate the flow rate with precision. This valve eliminates the need for additional inline flow control valves, making the setup more efficient and compact. The valve allows operators to fine-tune the flow as needed, improving control in sensitive or variable process conditions.
The acrylic body is not only lightweight but also highly resistant to corrosion from water and many non-aggressive chemicals. Its clear construction makes it easy to inspect the internal float and flow scale, which is marked in LPH units for immediate, accurate readings. The float is typically made from stainless steel or PTFE, depending on the model, both of which offer excellent durability and corrosion resistance.
One of the biggest advantages of this rotameter for water is its non-electric nature. It does not require any power source or battery, making it a truly maintenance-free solution for continuous flow monitoring. This makes it especially useful in remote or space-constrained areas where wiring and electrical equipment may be impractical. The device functions on the variable area principle — as the flow increases, the float rises in the tapered tube, with its position indicating the corresponding flow rate.
In terms of performance, the rotameter for water offers a flow accuracy of ±2% of full scale, making it dependable for applications where flow consistency is crucial. The instrument can handle pressures up to 10 Kg/cm² (150 PSI) and temperatures up to 60°C, making it suitable for a wide range of standard water handling applications. Installation must be done in a vertical orientation, with the flow direction from bottom to top, as required by its working principle.
The 0 to 200 LPH acrylic tube rotameter is widely used in industries like water treatment, HVAC, pharmaceuticals, laboratories, chemical processing. Common applications include RO systems, cooling water circuits, pilot plants, test rigs, boiler feed monitoring, air washers, and effluent treatment plants (ETP/STP). The combination of accurate performance, simple design, and long service life makes this rotameter a preferred choice for engineers, plant technicians, and OEM system builders.

It is an ideal solution for engineers who require dependable and maintenance-free flow measurement tools without the complexities of digital electronics or complex calibration. The product is designed to be easily installed and operated, even by non-specialized personnel, reducing downtime and training costs.
This rotameter offers a compact design that fits well into small control panels and skids. Its clear scale and float visibility ensure easy readability even in dim lighting conditions, further improving its usability in various work environments. Additionally, the side-entry connections simplify tubing layout and allow for streamlined panel design.
When ordering this product, it is helpful to confirm the desired flow range, media compatibility (typically water), and float material if you are working with any special fluids. Japsin Instrumentation also provides customized options if your application requires different ranges, connection sizes, or specialized float materials for aggressive chemicals.
In summary, the “Ji” Japsin Instrumentation Acrylic Tube Rotameter for water is a proven and efficient solution for measuring and controlling low to medium water flow rates in a wide range of industrial and lab settings. Its transparent acrylic body, built-in inlet valve, durable float materials, and user-friendly design make it one of the most practical flow meters in its class. Supported by Japsin Instrumentation’s quality assurance and technical expertise, this rotameter delivers excellent value and performance in every application it serves.
