FM-40 Flow Meter (1-in)

METER’s new flow meter offerings combine the accuracy of positive displacement meters with the reliability and economy of nutating disc technology. Constructed out of engineered polymer, our flow meters are user serviceable and certified to NSF/ANSI Standards 61 and 372. The meters include a magnetically driven register, a pulse transmitter for digital output (no power required), and meter connection fittings. These meters offer minimal pressure loss making them ideal for retrofitting existing irrigation systems.
