Product Information

[Discontinued Product]Ultrasonic Level Meter LIU-320

Product Description

● Description
Differ from old type supersonic level meters, LIU-320 permits measuring all type of measured matters such as ores, bulk level, slurry, and refuse.   In addition, "higher-safety explosion-proof model" has been improved to measure chemicals, combustible materials, etc.

● Features

・ It can measure a wide range of measured matters such as fines (cement, collected dust, etc.), chemicals, ores, water supply and drainage, and snow.
・ Less polluted electrode because of non-contact with measured matters, and not affected by chemical changes due to vapor, gas, or chemicals because of its corrosion resisting structure.
・Using high water-proof IP-54 for the converter.
・It equips noise eliminator, and is designed to be high resistance to noise, surge, and thyristor noise. This permits continuously output.
・A self-diagnostic function using upper and lower contacts and many sensors is mounted.
・The output is an analog output of DC4 to 20 mA . The output circuit is isolated. Regarding the display, any desired unit such as %, m, and mm can be set as a value unit. Analog display can also be promoted by bar at the same time. This facilities checks in the work site.
・ Loop check simplified by using the test mode
・Easy ZERO SPAN adjustment.
・ With the CPU and memory mounted, any adjustment can be made by simple button operation according to the work site.
・ The converter can be installed on the wall or installed on a stanchion by using 50a pipe. They can be adapted to any work site by simple installation work and require only simple maintenance.
