LRR300 Electric Wave Type Level Meters

LRR300 Electric Wave Type Level Meters

The LRR300 electric wave type level meters is a measuring instrument that uses microwave technology to measure the level of the liquid surface having a dielectric constant. It measures the water levels of the city water and sewage facilities, waterway, tank and dams, and then converted to 4-20mA DC signal and sent out. Also, in a non-contact object that to be measured, because it contains no mechanical moving parts, it is a reliable instrument.

Feature

  • Because it uses feeble electric waves, there is no restriction to use it in locations such as cities, rivers, and seas (Feeble electric wave equipment confirmed)
  • Because it uses microwaves, the measuring object is not affected by the temperature, the pressure and the wind. It is possible perform measurement in an environment with a lot of water vapor.
  • Because it employs non-contact, no mechanical moving parts, it is a reliable and easy to maintain.
  • Because it has a built-in calculation functions, you can also calculate the storage capacity of the tank.
  • Because it adopts two-wire system, and the power supply voltage is 24V DC, installation is easy.
