Turbine Flow Meter YYTB Series

YOYI YYTB series product view

YOYI YYTB Series · precise, economical metering of clean liquids

Proven Technology for Custody and Batching

The YOYI YYTB series turbine flow meter converts the rotational speed of a free-turning rotor into a flow-proportional pulse train. Simple, precise and economical, it remains the workhorse for clean, low-viscosity liquids from fuels to water.

How It Works

Fluid passing the meter spins a multi-blade rotor whose speed is proportional to velocity. A magnetic or inductive pick-up counts blade passes and generates a pulse train, so each pulse represents a fixed volume.

Because the signal is digital and resolution is high, turbine meters integrate cleanly with batch controllers and totalizers — the reason they remain standard on loading arms and dosing skids.
