Micro turbine flow meter with tiny DN4~DN50 sizes, compact threaded structure, 304 stainless steel body. It delivers high-precision measurement for low-flow clean liquids, supporting pulse, 4-20mA and RS485 signals for laboratory and small pipeline metering.
Ultra-small caliber DN4–DN50, compact threaded structure for narrow tiny pipelines
Sensitive mini impeller, fast response to slight flow fluctuations
Multiple signal outputs: pulse, 4-20mA, RS485 Modbus
Simple installation & disassembly, ideal for lab, instrument and small chemical lines
Wide turndown ratio, stable performance under small flow working conditions
