ESMK28 Oval Gear Flow Meter for Diesel gasoline kerosene methanol water

The K28 oval gear flow meter is a micro-volume digital flow meter that relies on a pair of precisely meshed oval gears. Driven by the fluid pressure difference, the gears rotate, dividing the liquid into measurement chambers of fixed volume, and accurately measuring cumulative flow through the gear rotations. It has a built-in Hall sensor to collect signals, paired with an LCD screen to display instantaneous and cumulative flow in real time, supports unit switching and data reset, making operation intuitive.

The product has a compact structure and lightweight design, uses threaded connections, and does not require straight pipe sections for installation, fitting various piping scenarios. The main body is made of engineering plastics or stainless steel, withstands a pressure of 2.0MPa, and has an IP65 protection rating, suitable for industrial oil and dust environments. It has a measurement accuracy of ±1%, a flow range of 1–50L/min, and strong compatibility with high and low viscosity liquids such as diesel, gasoline, engine oil, and methanol. The higher the viscosity, the less leakage and the more stable the measurement.

It does not require an external power supply, powered by a built-in battery with long endurance, widely used in fuel filling, small flow chemical transport, lubrication oil measurement, and other scenarios. It is a cost-effective choice for small-diameter, high-precision liquid measurement.
