High-Precision Gear Flow Meter Water Sensor DN15/DN20 for Diesel Hall Flowmeter

Achieve precise flow measurement with the High-Precision Gear Flow Meter Water Sensor DN15/DN20, delivering ±1% accuracy for water, oil, and milk across DN15/DN20 connections.

Powered by a wide DC 3.5-24V supply and drawing ≤10mA at 5V, this PPS-bodied sensor offers four thread sizes—G1/4, G3/8, G1/2, and G3/4—for flexible plumbing in compact applications.

Benefits & Tips

• Versatile for non-corrosive, low-viscosity liquids (water, oil, milk) with a robust PPS construction for extended durability.
• Choose from multiple interface sizes (G1/4, G3/8, G1/2, G3/4) to fit common piping and ensure a secure seal.
• Monitor flow with high accuracy and interpret signals using the provided frequency formulas to estimate real-time flow rate across sizes.
