overview

The LWGY turbine flow sensor is paired with a display instrument to form a turbine flow meter. Sensors have the characteristics of high accuracy, good repeatability, long lifespan, and simple operation. It can be widely used in industries such as petroleum, chemical, metallurgy, and papermaking to measure the instantaneous flow rate and total volume of liquids.

characteristic

The pressure loss is small, and the impeller has anti-corrosion function.

Has high resistance to electromagnetic interference and vibration, reliable performance, and long working life.

Adopting advanced ultra-low power single-chip microcomputer technology, the whole machine has strong functions, low power consumption, and superior performance. Intelligent flow display with non-linear accuracy compensation function. The accuracy of the correction formula is better than 0.02%.

The instrument coefficient can be set online through buttons and displayed on an LCD screen, which is intuitive, clear, and highly reliable.

Using EEPROM for power down protection of accumulated flow and instrument coefficient. The protection period is greater than 10 years.
