LUDC miniature vortex flow meter adopts piezoelectric sensor and stainless steel body for tiny pipelines. It measures gas & liquid with ±1.5% precision, supporting isolated 4-20mA and RS485 Modbus for micro liquid flow monitoring.
Mini DN8/12/15 small-caliber design, NPT male thread compact connection
Piezoelectric detection, no moving parts, low pressure loss, minimal maintenance
±1.5 measurement accuracy, independent of medium density & viscosity
Dual isolated output: 4-20mA analog + RS485 Modbus RTU communication
LCD bilingual display, shows instantaneous & cumulative flow values
Adjustable damping and small signal cut-off to eliminate zero drift
IP65 protection, DC24V power supply, integrated compact structure
Configurable flow unit, density & temperature-pressure compensation parameters
Password-locked menu to avoid unauthorized parameter modification
