Description

The Badger Meter® M7600 flow meter combines the most advanced electromagnetic flow metering technology with a simple, yet robust, output for batching systems found in industrial applications. Based on Faraday’s Law of electromagnetic induction, M7600 meters can accurately measure and control most batching needs in the industrial market. Its completely open cross-section flow tube design with no moving parts, makes it the ideal metering device for batching of a wide range of industrial conductive fluids. While other metering technologies are hindered by the presence of suspended solids in the process fluid, the M7600 will continue to measure flow, provided the conductivity remains higher than 5 microhms/cm. Having a non obstructive flow-through pipe design allows particulates to pass through the meter body. The signal voltage, measured by the electrodes, passes through the entire cross sectional profile for improved accuracy. The M7600 meter features an intuitive PC interface used for selecting the scale factor, unit of measure and pules per unit, making these meters the most straight-forward metering systems available in the Industry.

Operation

The M7600 meters have stainless steel flow tubes with internal isolating linings. Two electromagnetic coils are located outside the flow tube, diametrically opposed to each other and protected by a carbon steel housing. Two electrodes, inserted into the flow tube, are positioned flush with the internal diameter of the tube and perpendicular to the coils. The coils are energized by a pulsed DC voltage provided by the electronic converter, and a magnetic field is generated across the flow tube section. According to Faraday’s law, when this magnetic field is cut by the conductive liquid flowing through the meter, a voltage is generated in the liquid. This voltage is directly proportional to the liquid flow velocity, and therefore to the actual volumetric flow rate of the liquid. The electronic converter measures this voltage, processes the signal, and provides two digital pulse outputs, scalable to the desired volumetric value. These digital pulse outputs can be connected to a batch controller, a totalizer display unit for monitoring purposes, or to both devices simultaneously. The operation of the M7600 meter is not affected by a moderate presence of most suspended solids in the liquid. Variations of liquid temperature, viscosity or density have no influence in the principle of operation.

Application

Because of its inherent advantages over other more conventional technologies, the M7600 meter can be used in the majority of industrial process batching applications and is the meter of choice for concrete batching operations. Whether the fluid is water or something very viscous, contains a moderate amount of solids or requires special handling, the M7600 meter will be able to accurately provide flow measurement.
