The Neptune 4D-MD meter has long been the standard for accuracy and reliability in LPG dispensing applications. At Red Seal Measurement, we value our customers’ suggestions for product improvement. Based on feedback from the field, we’ve identified several modifications to enhance the performance and durability of the 4D-MD, and after rigorous evaluation, we’re pleased to announce their implementation. Some of these changes have already been incorporated, and the remainder are being introduced into production beginning May 1, 2018.
