120 LPH Rotameter

The 120 LPH Rotameter  is a flow meter designed to measure the flow rate of liquids, specifically water. It is commonly used in reverse osmosis (RO) systems to monitor the flow of permeate (filtered water) and concentrate (wastewater).

120 LPH Rotameter Features and Specifications 

Flow rate 120 Liters Per Hour (LPH)


Material Acrylic body


Connection size 1/2 inch
Maximum operating temperature 50°C
Dimensions: 15 x 24 x 29 cm



  1. We provide the best rotameters for flow measurement in RO systems.
  2. Consumes zero electricity as it uses the pressure buildup from fluid flow along with gravity to provide accurate flow measurement.
  3. Uses clear glass so very resistant to thermal shocks and chemical reactions.
  4. This is one of the most cost effective solutions for low pressure and non-corrosive fluids.

Rotameter LPH 120 Advantages

  1. Affordable:Compared to other types of flow meters, rotameters are a relatively inexpensive option.
  2. Easy to read:The flow rate is displayed on a clear scale, making it easy to read even in low-light conditions.
  3. Simple to install:Rotameters require minimal installation and can be easily integrated into existing RO systems.
  4. Low maintenance:They have no moving parts that can wear out, making them virtually maintenance-free.

Considerable Factors before buying

  • Accuracy: Rotameters are not as accurate as some other types of flow meters, and their accuracy can decrease over time.
  • Limited flow range: They are only suitable for measuring flow rates within a specific range.
  • Pressure sensitivity:The flow rate reading can be affected by changes in pressure.


  • Monitoring permeate flow in RO systems
  • Measuring flow rates in other water treatment applications
  • Industrial applications where a simple and affordable flow meter is needed
