They all leak. ### ⭐ Flowmeter design does not work *by D***G on August 22, 2023* The rotary blades used within this hall effect flowmeter are tapered such that they have a variable width. Because of this, water can easily pass through gaps between these blades and the flowmeter casing which basically renders flow data as garbage. Digiten also utilizes this completely useless design.
