The rotor is magnetically connected to a shaft which in turn is connected through gears to a readout register The turns of the rotor are indicated on the register Meter Operation See M306 Cross section View on previous page The process liquid enters the metering chamber through the inlet connection As the liquid follows the 360 degree loop it is separated into two equal streams These two streams are forced into a series of vortices in the body and cover inserts and cause the rotor to rotate in proportion to the rate of flow Rotation of the rotor is transmitted through the shaft and gears to the register assembly where the liquid flow is indicated Both liquid streams rejoin at the meter outlet which is in direct line with the meter inlet Startup Procedure A Practical Considerations The following practices should be observed when installing and starting a Flotrac meter See cross sectional illustration above and by pass location drawing at the top of the next page 1 Strainer A strainer should be installed upstream from the Flotrac meter if rock fragments weld slag or debris may be introduced into the flow line Some sand is permissible Water Treatment If dissolved calcium carbonates CaCO3 or salts are excessive treat ment is required to prevent scale buildup on the rotor journal and housing parts Air Eliminator If the liquid stream contains substantial amounts of dissolved gas or vapors an air eliminator sho
