McCrometer has set the standard for liquid flow measurement performance, ease-of-use and value in the agricultural and turf markets since 1955. Our leading-edge propeller flow meters offer economical and versatile flow measurement. The McPropeller meter is especially suited to dirty water flows, municipal and other high-volume water applications.
Trusted by Farmers since 1955

Unlike traditional types of water meters, the McPropeller uses a flexible drive-train and sealed ball bearings. Its unique design makes it easy to service in the field and requires no external power or batteries. The McPropeller flow meters are designed to comply with AWWA C704-08. Standard features include an instantaneous flow rate indicator and six-digit totalizer. There are no tight tolerances in the McPropeller. It handles solids suspended in water without clogging. With its high accuracy, this flow meter is also a water management tool, helping to reduce water costs, preventing over-irrigation and reducing leaching of chemicals and fertilizers into the ground.

APPLICATIONS:

McCrometer's McPropeller flow meters operate in a wide variety of environments without damage or loss of accuracy. They deliver ± 2% of true accuracy and ± .25% repeat-ability over a flow range of 25 to 1. Whether measuring clean or dirty fluids, McCrometer's McPropeller flow meters excel in measuring turbulent flows, and their built in versatility makes them ideal for retrofits.

* Register options: forward/reverse flow; test hand/index wheel; anti-reverse totalizer; custom scale; extended digit totalizer
* Impeller options: high temperature resistant; acid and caustic resistant
* Line sizes: from 2" to 96"

ADDITIONAL INFORMATION:

How it Works:
* The McPropeller consists of a rotating device, a helical-shaped impeller, positioned in the flow stream
* When fluid passes through the meter, it contacts the impeller causing it to spin
* The impeller's rotational velocity is directly proportional to the velocity of the flow
* The rotation is translated through a magnetic coupling and flexible drive system to the register, which calculates the flow rate by multiplying the flow velocity with the cross–sectional area of the meter tube.
