The document describes the Oval gear mechanical flow meter produced by JSN. It provides precise volumetric flow measurement of clean liquids across a variety of industries. Key features include a compact and economical design, high accuracy and repeatability, and measurement of both high and low viscosity liquids without requiring flow conditioning. The chief engineer is formerly from Siemens and the equipment uses Siemens CNC machines to achieve high performance standards with minimum flow rates as low as 0.1ml/min and pulse ratios of 1ml/pulse.
