Master Meter’s PD meter’s whisper quiet chamber is engineered to accurately measure even when pressure is low.

Science Backed Measurement Design

By using the latest Computational Fluid Dynamic (CFD) design principles; our engineering department surpassed performance benchmarks which have been ignored by our competition for more than a 100 years.

New Meter Accuracy After a Lifetime of Use

In independent accelerated lifetime accuracy testing conducted by The Utah Water Research Laboratory conducted an accelerated lifetime accuracy test using our MMPD. The MMPD maintained new meter exactness after 35 years of simulated wear which was 4,000,000 USG of usage. The MMPD achieves these results by improved chamber design, using new materials design, and by using bleeding edge design software.
