Product Introduction:
The Hollysys HT57 Micro Flow Float Flowmeter is a compact, reliable instrument designed for precise measurement of low-volume liquid flows in industrial and laboratory environments. Utilizing a float-and-cone principle, it offers clear visual flow indication and stable performance across a wide range of media, including water, oils, and corrosive liquids. The HT57 is ideal for applications requiring accurate monitoring of small flow rates, such as chemical dosing, coolant systems, and process control.
Product Principle:
The HT57 operates on the variable area principle: as the fluid flows upward through the tapered tube, the float rises to a position where the upward force from the flow equals the float's weight. The float's position corresponds to the flow rate, which is visually indicated on the graduated tube. This mechanical design ensures minimal pressure loss and simple installation without external power.
