M7K1 meter system from Liquid Controls, built on the M7 rotary positive displacement platform with electronic LCR2 registration and an internal pulser. Flow runs right to left in 1/10 gallon increments, with Buna seals, a block valve, mechanical air eliminator, metal inlet, and a hi-cap 40 mesh strainer; the system carries NIST conformance. The M7 element uses three synchronized rotors that turn with no metal-to-metal contact, so hydraulic sealing comes from a stationary boundary layer of liquid rather than wiping mechanical parts, which keeps accuracy from deteriorating with wear.
