This economy water flow meter is an ideal alternative to traditional water meters. The TM Series water meters offer flow rate and flow total indication that help monitor water flow in wastewater applications, water treatment, and sub-metering applications. The battery powered electronic display TM Series water flow meters are calibrated to read in gallons and liters per minute, and cubic feet. These water flow meters also have two totals in which case one is resettable and the other gives you cumulative flow totals.
