Review on Uxcell A11072800Ux0014 Black Adjustable LZM 15 by Steve Harris

This is an excellent water flow meter! It uses a thin needle valve for very precise and consistent flow control, not "hissing" as air is sucked in when water is flowing through it. Perfect fit for a panel I designed and built for myself. I mounted it on a 5/16 inch thick nylon cutting board where the mounting screws on the gauge are 3/8 inch thick so they barely work. The rear connectors have 1/2" plastic pipe threads that are perfect for the regular brass adapters you need to use, but don't over tighten! Highly recommended for very thin and accurate water flow measurements.
