1.1 Function
The 6600 Series is a low cost, Electromagnetic Flowmeter that combines ease of use and reliability to accommodate
a wide range of applications.
In the standard 6600 Series of Magnetic flowmeters, the SENSOR and the ELECTRONICS form one mechanical
entity. In the optional high temperature version for temperatures up to a maximum of 248° F (120° C) or for fluid
temperatures exceeding 176° F (80° C), the electronics are remotely mounted, and can be installed up to 330 feet
away from the sensor depending on conductivity.
The SENSOR consists of a metering tube, electrodes and coils. The electrodes and coils are in a welded fully
encapsulated sheet metal enclosure that is filled with polyurethane. This prevents the internals of the sensor from
becoming exposed to moisture and environmental conditions. The SENSOR rating with integrally mounted
electronics is IP67 (protection against entry of dust and low pressure jet of water from all directions, NEMA 4X), with
Remote Electronics IP67 (protection against entry of dust and submersion in water, NEMA 6P).
The conditioning ELECTRONICS circuitry is housed in a cast aluminum box with IP67 (protection against dust and
limits submersion to 3.2feet/1 meter, NEMA 6) protection. The termination of the electronics is given in an adjacent
cast aluminum housing with ½-inch NPT fittings for the required interface cables
The flanged meter is available from 1/2 to 24 inch sizes. Hastelloy Stainless Steel electrodes (150#,carbon steel
flanges) are standard, but several other electrode materials such as 316SS, Titanium, Monel, Platinum Rh etc. are
available.
The 4-20 mA output proportional to flow can be fed to a PLC, DCS or remote mounted indicator. An optional 24 V
DC pulse or frequency output can be connected to external devices such as a totalizing counter.
The complete instrument consists of a sensor and a controller.
Sensor: The sensor consists of the metering pipe, electrodes and magnetic coils. It is encapsulated in a fully
welded sheet steel enclosure that is filled with polyurethane to prevent exposure to moisture and environmental
conditions.
Controller: The controller contains the electronics that is used for driving the magnetic coils, conditioning the
electrode signal and providing the outputs. It may be mounted integral with the sensor or on a wall.
Compact Version: In the compact unit, the controller and the sensor form a single mechanical entity.
