Product Application

Widely used in urban sewage, water resource management, agricultural irrigation, garden management, industrial production, industrial automation control and other industries, it is a major innovation in water management technology.

Product Features

• Protection level IP68
  Whole machine: The whole machine is sealed to IP68 protection level
  Components: Each component individually achieves an IP68 protection level,
  Even if the watch body is flooded, it can still work for a long time.
• Built in quantitative controller and time-sharing accumulator
  Automatically start the controller at the set time to achieve automatic timed and quantitative water supply or irrigation;
  Accumulate traffic in a timed manner within a set time period to achieve gradient rates.
• Thermal measurement
  Equipped with dual PT1000 temperature measurement function, it can achieve heat metering,
  Especially suitable for the air conditioning and refrigeration industry.
• High-precision measurement
  Fluid layering dual channel measurement, accurate measurement.
  Ultrasonic measurement, no rotation, no worn parts, long-term guarantee of measurement accuracy, high reliability of the whole machine.
  Suitable for various water qualities, including those containing gravel and weeds.
