EDM Electronic Water Meter
The EDM series water flowmeter is excellent for accurately totalizing water and other low viscosity liquids. It features an economical PVC body and lithium battery powered LCD display. The display has a resettable batch totalizer and a non-resettable grand totalizer, as well as rate indication. These displays are accessed by a toggle push button on the face. The EDM is factory calibrated for water flow. This calibration is valid for low viscosity liquids up to 10 centistokes viscosity. For higher viscosity liquids, a field calibration mode exists allowing the user to dispense a known volume of liquid in order to calibrate the EDM’s computer for the higher viscosity liquid.The EDM electronic water meter is available in line sizes from 1/2 to 4 inches. Fittings available are PVC socket or NPT threads (150 LB ANSI Flanged connections also available for 3" and 4" units). The EDM series combines economy with a full featured electronics making it an excellent and economical replacement for metal body mechanical water totalizers.
