compact version 2-wire series / HLT
- HLT series compact 2-wire ultrasonic level meters power supply (DC24V) and signal output (DC4-20mA) share a common return circuit, using only 2 wires.
Use: Measurement for the liquid location or the material location.
Applications: It can guarantee the ultrasonic wave to traval to the occasion of measured liquid or material surface effectively. For instance: Store pot , material trough , pond , well , ditch , measuring case , granary , material storehouse ,etc..
Features:
• Integrated design, installed conveniently
• 2 wire transmitter standard, guarantee that the powerful sound wave is launched , that measurement is steady and reliable
• Protected in the excessive voltage and current , protected in the thunder and lightning
• The big show window of LCD is easy to debug and observe
• Intellectual signal treatment technology, guarantee that the instrument meets various kinds of operating occasion
• All plastic outer cover ( IP67 ), airproof and alkali-resisting, meet the abominable environment
• Flexible support or flange are used to install
Measuring Range ：
Liquid level: 4m 6m 8m 10m 15m 20m 30m
Solid level: 3m 5m 7m 10m 15m
When using to measuring solid level, the most energy of ultrasonic is absorbed or scattered by solid level, so the back wave is very little, the valid measuring range of solid level is about 50% of liquid level.
Whole Structure:
There are three kinds of forms in level meter:
