LU20 series integrated ultrasonic level gaugeDetailed product description：

LU20 series integrated ultrasonic level gauge (within 5.48 meters)

characteristic
☆ Non contact, 4-20mA output level gauge
Accurate and reliable measurement within 0.5 feet (15cm) to 18 feet (548cm)
☆ Equipped with full range automatic temperature compensation function
☆ 8-degree beam angle suitable for applications in limited installation space environments
☆ NEMA4X sturdy shell PVDF material all plastic structure
LCD digital liquid level display in inches or centimeters
☆ Easy Cal button calibrates all user set points
☆ Echo MAPTM filter eliminates incorrect echo signals
☆ Intelligent failure protection ensures that echo signals are not lost
application
Suitable for industrial agents including hydrochloric acid, hydroxides, wastewater, resin adhesives, waxes, alkaline solutions, and bleaching agents
Technical Principles
If there is agitation or foam in the liquid, a 2-12 standard catheter can be installed under the level gauge. With the support of Echo PipeTM software, the requirements of sound waves on the measurement space are reduced, so as to achieve accurate measurement.
