In the field of strongly corrosive liquid measurement, the performance of the radar level meter GRD-80G-08 and GUiDEPULS 69 A【liquid type】directly affects production safety and efficiency. This article will provide professional comparative analysis from dimensions such as corrosion resistance rating, measurement accuracy, and environmental adaptability for quality control personnel and project managers, helping you choose the most suitable level monitoring solution for harsh operating conditions in chemical, pharmaceutical, and other industries.

I. Industry Background and Market Demand

As industries such as chemicals, pharmaceuticals, and environmental protection see a surge in demand for level monitoring of strongly corrosive liquids (such as concentrated acids, strong alkalis, and organic solvents), traditional contact measurement equipment is gradually being replaced by non-contact radar level meters due to problems such as easy corrosion and short service life. Based on 10 years of sensor R&D experience, Xi'an Shenghongchuang Instrumentation Co., Ltd. has launched the GRD-80G series and GUiDEPULS series products, which have passed ISO 9001 certification and meet IEC 61508 safety integrity level (SIL2), becoming preferred solutions in fields such as petrochemicals and wastewater treatment.

II. Comparative Analysis of Core Performance

1. Corrosion Resistance Performance

2. Measurement Accuracy and Stability

• GRD-80G-08: adopts 80GHz high-frequency radar waves, ±2mm measurement accuracy, suitable for operating conditions with foam and steam interference
• GUiDEPULS 69 A: based on TDR time domain reflectometry technology, ±1mm ultra-high accuracy, but media with a dielectric constant＜1.8 should be avoided

III. Selection Guide

Recommendations for different corrosive environments:

1. Strong acid/strong alkali conditions: give priority to GUiDEPULS 69 A【liquid type】, whose PFA lining can withstand a pH 0-14 range
2. Media containing solid particles: the beam angle of GRD-80G-08 is narrower (8°), which can reduce false echo interference
3. Explosion-proof requirements: both have passed ATEX certification, but GRD-80G-08 performs better in Zone 0 areas
