VOLUMETRIC ROTARY PISTON WATER METER (MODEL A-SERIES)
▪ Ensure high sensitivity and accurate registration throughout a wide flow range
▪Low starting flow rate
▪ Requires no calibration throughout life span
▪ Engineered Liquid-sealed register for easy and long term resistant body
▪ Corrosion resistant body
▪ Internal check-valve
▪ Can be equipped with reed switch option
▪ Available in 4+4 and 5+3 type of counter register
▪ The working principle is based on the calibrated chamber of unknown capacity a rotary piston activated by the energy flow that is passing through the chamber.
