Radar Level Gauge: 5-Minute Quick Start Guide

I. What is it?

A radar level gauge is like a "smart ruler" for storage tanks:

Working Principle: An antenna transmits microwaves, which are reflected by the material, and the liquid level is calculated by calculating the time difference.

Key Features:

✅ No contact with the material (measuring in mid-air)

✅ High-temperature and high-pressure resistant (operable from -200°C to 400°C)

✅ High accuracy (minimum error ±1mm)

II. When is it used? (Applicable Scenarios)

Scenarios: Pain Points of Traditional Instruments; Advantages of Radar Level Gauges

Chemical Storage Tanks: Corrosion Damage; Stainless Steel Housing Resists Corrosion

Food Tanks: Difficult to Clean; Smooth Surfaces Offer One-Click Cleaning

Dust Silos: Dust Interference Failure; Microwaves Penetrate Dust

Highly Foamy Liquids: Measurement Jumps; Intelligently Identify the True Liquid Level

III. Three-Step Model Selection

Frequency:

Small Tanks → 26GHz (High Accuracy)

Large Tanks → 6GHz (Large Range)

Viscous Media → 80GHz (Anti-Adhesion)

Antenna Selection:

Liquids/Particles → Horn Antenna (General Purpose)

Thin Gases → Waveguide Probe (Strong Signal)

Function Selection:

Explosion-Proof Areas → Select with Ex Certification

Food and Pharmaceuticals → Select Hygienic Type

IV. Installation Guidelines

✅ Correct Operation:

Vertical Installation (Tilt < 3°)

Avoid the Inlet (Prevent False Echoes)

Leave a Blind Spot (Leave 0.3m Clearance at the Tank Top)

❌ Prohibited Operations:

Installing next to a blender

Ignoring the thickness of the foam layer

Using without calibration

V. Super Simple Maintenance

Cycle

Operation

Tools

Monthly

Wipe the antenna with an alcohol wipe

Soft cloth + alcohol

Quarterly

Check the signal strength (>-20dBm)

Instructions

Annual

Calibrate the zero point

Press the SET button

VI. First Aid Kit

No signal: Clean the antenna first, then check the power supply.

Data jumps: Enable the "Filtering" function.

ERR display: Restart and recalibrate.

In short: Radar level gauge = non-contact + durable + accurate. Choose the right model for ten years of peace of mind!
