Call for pricing
The M-10000 Paddlewheel Flow Meters are smaller, easier to install, and more accurate than previous models. Optional outputs such as 4-20 mA, 0-10 VDC, or pulse are available the M-10000 Paddlewheel Flow Meter. Additionally, the M-10000 Paddlewheel Flow Meters can also be used as an adjustable flow switch and are available in both metal and plastic design configurations.

Paddlewheel flow meters, also known as tangetial turbine flow meters, continue to be the most common way to measure flow electronically in a wide range of industries. Enhancements to the M-10000 Paddlewheel Flow Meter created a flow-sensing device that is smaller, easier to install, and more accurate than previous models. Malema M-10000 Paddlewheel Flow Meters that utilize sophisticated circuitry to foster signal conditioning.
