DR6421 Non-Contact Radar Level Transmitter for Chemical Tanks
The $30,000 Mystery: Why Our Chemical Inventory Didn’t Match
The bubbler read half full, while the dip tape said empty. Our chemical tanks were a mystery, with $30,000 of valuable reagent unaccounted for. This discrepancy wasn’t just a measurement error—it was a costly blind spot that threatened production planning and safety. We needed a solution that could provide accurate, reliable level data without the risk of contamination.
What Our Bubbler and Dip Tape Didn’t Tell Us About Tank Level Accuracy
Bubblers rely on hydrostatic pressure, which can be skewed by density changes, temperature gradients, and gas absorption. Dip tapes, on the other hand, are prone to human error and require tank entry, increasing safety risks. In our case, the bubbler’s reading drifted due to reagent vapor condensation in the purge line, while the dip tape was misread by an operator. Consequently, we were operating with false data, leading to over-ordering and waste. Radar technology, however, uses time-of-flight of electromagnetic waves, which are immune to such process variations. This means a non-contact level sensor like the DR6421 can measure through tank roofs without process penetration, eliminating contamination risks and providing true level data.
How DR6421 Solved Our Chemical Level Measurement Inaccuracy
After an extensive investigation, we identified the issue as a combination of inaccurate bubbler readings and misleading dip tape measurements. The DR6421 radar level transmitter offered a reliable alternative that could accurately measure liquid levels in high-temperature tanks without physical contact. Its 4-20mA or RS485 output options integrate seamlessly with our existing DCS. Moreover, the sensor has no moving parts, ensuring low maintenance even in corrosive environments.
$30,000 Recovered: How Accurate Radar Level Measurement Paid for Itself in Six Months
We installed several DR6421 units across our chemical tanks and corrosive liquids storage areas. The results were immediate: the DR6421 provided consistent, accurate measurements that correlated with our production volumes. The cost savings from reduced material waste alone paid for the upgrade within six months. Additionally, we eliminated unsafe tank entries and reduced maintenance downtime.
