DN20 TO DN25 Flow Sensor Adapter | Dual Calibration | SAIER

SAIER DN20〜DN25 真鍮製流量センサー | 一体型減速機設計 | 100℃高温 | デュアルキャリブレーション（2〜45L/分）

Why waste space and risk leaks with extra brass reducers? The SAIER DN50-DN25 Integrated Brass Flow Sensor acts as both a high-precision meter and a structural adapter, transitioning your line from DN20 to DN25 seamlessly. This “leak-killer” design eliminates unnecessary threaded joints, making it perfect for cramped boiler cabinets and heat pump manifolds.

Engineered for precision, it features gravity-compensated algorithms for both orientations: Horizontal ( $F = [8.1Q - 5] \pm 10\%$ ) そして Vertical ( $F = [8.1Q - 3] \pm 10\%$ ). Crafted from heavy-duty brass for temperatures up to 100℃, it’s the ultimate G3/4 composite thread solution for engineers who refuse to compromise on data accuracy or system compactness.
