GALONMETER GL-MJ-AWWA is magnetically driven multi jet (Velocity) water meter with Super Dry Type Register from size 5/8X1/2” to 2” designed by GALONMETER and meets to AWWA C708.
OPERATION:
Water flows through the meter’s strainer and into the measuring chamber where it drives the impeller. A driving magnet transmits the movement of the impeller to a driven magnet located within the hermetically sealed register. The magnet is connected to a gear train which translates the impeller rotates into volume totalizators displayed on the register dial face.
CONSTRUCTION:
GALONMETER PMN bottom loaded Water Meter consists of three basic components: main case, measuring chamber and a sealed register. The main cases of all sizes are constructed using Brass Alloy or Bronze Alloy or Lead free Brass Alloy. Measuring Chambers are constructed of a durable synthetic polymer. Bottom plates are Brass Alloy. Registers are available as either direct read or electronic output with Plastic Register Cover and plastic Register Shroud, Brass Register Cover and brass Register Shroud AS OPTION.Dimension and Dial Plate Design for USG (CF and m3 AS OPTION):
