LUDC\/S Series Small Diameter Vortex Flow Meter | High Precision for Liquids & Gases DN8\u2013DN15<\/p>\n\n\n\n

Meta Description<\/h2>\n\n\n\n

LUDC\/S micro\u2011bore vortex flow meter for DN8\/12\/15 small pipes. Measures liquids & gases, 4\u201320mA + RS485\/Modbus, 316SS, IP65, low pressure loss. Ideal for precision industrial flow monitoring.<\/p>\n\n\n\n

\n\n\n\n

1. Introduction<\/h2>\n\n\n\n

For small\u2011diameter pipeline flow measurement, traditional meters often face issues like large pressure loss, poor low\u2011flow sensitivity, and unsuitable dimensions. The LUDC\/S Series Micro\u2011Bore Intelligent Vortex Flow Meter<\/strong> from Suzhou Beite Smart Instrument<\/strong> solves these pain points. Designed for DN8, DN12, DN15 small pipes, it delivers stable, accurate flow measurement for both liquids and gases with long\u2011term reliability.<\/p>\n\n\n\n

2. Working Principle<\/h3>\n\n\n\n

Based on the von K\u00e1rm\u00e1n vortex street principle<\/strong>, the meter uses a piezoelectric stress sensor to detect vortex frequency, which is directly proportional to flow velocity. The meter converts frequency into standard output signals, nearly unaffected by fluid density, pressure, temperature, or viscosity. With no moving parts, it ensures high stability and minimal maintenance.<\/p>\n\n\n\n
