Rotarymeters

Rotarymeters
Wide turndown and high accuracy in a body far smaller than the flow suggests.
Two precisely machined impellers displace a fixed volume per revolution, giving the MT-R excellent accuracy right down to very low flow. Turndown up to 1:250 makes it the natural choice for industrial sites where demand collapses overnight and peaks during production — exactly the profile that defeats a turbine meter.

Frequently asked questions
What engineers most often ask when specifying this equipment.
It follows the flow profile. Wide turndown with low minimum flow favours rotary; high, steady flow favours turbine on cost; internal consumption monitoring that needs no fiscal approval is best served by a quantometer. Send us a load profile and we will size against it.
