Fellow Kogyo LIU-330 Ultrasonic Level Meter

Manufacturer: Fellow Kogyo Co., Ltd
Model: LIU-330

Description

This device measures a wide range of materials, including cement, dust, chemicals, ores, water, and snow. Its non-contact design reduces sensor pollution and resists corrosion from vapor, gas, or chemicals. The converter, featuring IP-66 waterproofing, withstands noise, surges, and thyristor interference, ensuring continuous output.

Equipped with noise eliminators, it offers stable performance. The analog output ranges from DC 4 to 20 mA, and the isolated circuit supports customizable displays in units like %, m, or mm. A bar graph enhances site checks, while the test mode simplifies loop checks. ZERO and SPAN adjustments are easy, and CPU-controlled settings enable quick on-site tuning.

The converter installs easily on walls or stanchions with a 50a pipe, suiting various work environments with minimal maintenance. The explosion-proof model enhances safety when measuring chemicals and flammable materials.
