Upgrade Mechanical Level Measurement to Radar Level Transmitters

Introduction

Level measurement is essential for stable plant operation in tanks and silos storing raw materials or products.

Traditional mechanical level transmitters such as sounding type level meters have been widely used in industrial facilities. However, these contact-type instruments often require regular maintenance and may suffer from wire-rope wear, mechanical failure, or measurement instability.

To overcome these challenges, many plants are now upgrading to radar level transmitters. Radar technology enables reliable non-contact level measurement even in harsh environments such as dust, vapor, and high temperature conditions.

Contact type level transmitters may get damaged especially at portions where contact with the process in the long-term usage and then may raise the risk of facility damage and foreign matter contamination.

Periodical maintenance or replacement of consumable parts are required in case of contact type level transmitters (or the one which has mechanical movable portion).

Ultrasonic level transmitter (or the one which uses air as emitting media) may cause malfunction (wrong measurement) according to conditions (vapor, dusty, etc.) in the silo or tank.

Solution

Radar Level Transmitter can solve those problems:

Measurement through the tank is possible because of the electromagnetic wave characteristic.

It's useful for corrosive gas conditions.

Parameter setting and wave form observation is possible with the handheld adjustment unit (GRAPHIC COM) other than the adjustment via PC.

Compatible with HART adjustment equipment.

Productivity improvement is achieved because it can reduce down time, troubles or maintenance time due to malfunction (wrong measurement), and stable plant operation is possible.

Unnecessary cost for supervising, parts replacement or unwanted maintenance work is reduced.
