Drinking Water Test & Flow Meters

Your source for quality water flow meters

Shop at Discount Filter Store first, for a wide range of water flow meters & controllers, water leak sensors, and digital sensors, to help regulate the flow of your water and keep your water clean and safe.  Water flow is measured to assess how much water is available and to check the quantity of water flowing through a system.  A steady and consistent water flow is essential to effectively and efficiently disinfect drinking water, especially in a RO water filter system.  Every one of our flow meters is made with the highest-grade materials to guarantee its continued use.  Not sure which flow meter you need, our customer service experts can help you choose the right water flow meter from our wide selection of flow meters.

Need a stronger water flow, check out our selection of booster pumps, designed to increase the flow rate of water through your system.
