LFD-420

The LFD-420 series are non-invasive transit ultrasound flowmeters for liquid fluids in pipes at full load.

This type of flowmeter is the ideal solution for flow measurement in products that are impossible to measure by other methods, or that it is not feasible to intervene in the duct, or there is a risk of leaks, such as with hydrocarbons or liquid fuels.

The LFD-420 measures fluid velocity by calculating the transit time between two separate transducers that function as both ultrasonic transmitters and receivers. The difference in transit time measured is directly and exactly proportional to the velocity of the liquid in the pipe.

Description

  • Fluid velocity m/sec. (positive or negative)
  • LCD display with accessible keyboard (IP67)
  • Instantaneous flow m3/h (configurable)
  • Total accumulated flow m3
  • Elapsed time (real time clock)
  • Automatic calculation of sensor position
  • Selection of pipe parameters, fluid and units
  • Output 4..20mA and Pulses of the instantaneous flow
  • RS485 Modbus communication
  • 24 Vdc power supply (or optional battery)
  • For ducts from DN25 to DN3000 in 3 versions

The LFD-420 transmitter allows the measurement of liquid flow in a wide range of pipes or ducts made of different materials, containing everything from ultra pure water to liquids with suspended solids, as well as viscous liquids, etc.

  • Water (hot or cold, drinking water, sea water, etc.)
  • Waste water containing small particles
  • Oil (crude oil, lubricant, gasoline, diesel, etc.)
  • Productos químicos (alcohol, ácidos, etc.)
  • Wastewater treatment plants
  • Ultrapure waters, Beverages, Liquid foods
  • Solvents and viscous products
  • Creams, Gel, Molasses, etc.
