Precise Measurement with Micro Flow Meters for Water

Micro flow meters are the unsung heroes in accurately measuring tiny water flows. The LC-M Series, a positive displacement flow meter, excels in detecting ultra-mini water flow, as low as 0.5 ml/min, while maintaining an outstanding accuracy of 0.5%F.S.

Working Principle of micro water flow meter

At the heart of these micro flow meters are gear-like rotors within a cavity. As the gears rotate, they create fixed volumes within the chamber. By counting the number of rotations within a set time, these micro water meters precisely measure the flow of water passing through.

The LC-M micro flow meters boast impressive technical specs for low flow water measurement:
  • - High Accuracy: +/-0.5FS
  • - Operating temperature range: -30~80°C (extendable to 250°C)
  • - Pressure handling: Up to 14503 PSI, can be used as high pressure micro water flow meter
  • - Output options: Hall pulse output, NPN or PNP
  • - Power supply: 4-26V DC
  • - Material options: Stainless steel 316L, aluminum, or PPS
  • - Suitable for various water pipeline sizes: 3/8", 1/4", 1/2", 3/4", 1"

Features and Technology of micro water flow meter

  • Sensitive Measurement Mechanisms: These micro water flow meters often use sensitive sensors to measure tiny flow rates accurately.
  • Compact Size: Designed to be small and compact, fitting into systems where space is limited or where the measurement area is confined.
