Manual measuring cup for measuring water flow in liters per minute, ideal for checks and adjustments on plumbing systems, boilers, and water distribution systems.
The cup is equipped with an adjustment lever that slides along a graduated scale from 0 to 17 L/min.
By moving the lever, an internal hole is progressively opened or closed to regulate the water flow.
To take the measurement, simply place the cup under a constant water stream and adjust the lever until reaching the balance point, where water flows in and out without the cup filling or emptying.
The value shown on the scale corresponds to the actual water flow in liters per minute.
Simple, practical, and reliable tool that does not require electrical power and is designed for quick use during inspection and maintenance.
