M-Series® 7500S

Sanitary Meter

DESCRIPTION

The M-Series 7500S Mag Meter, is a successful combination of the most advanced electromagnetic flow metering technology with the simplicity and ruggedness of proven batching systems for industrial applications requiring sanitary equipment.

Based on Faraday's Law of electromagnetic induction, the 7500S can accurately measure and control almost any batching requirement. The completely open cross-section flow tube design with no moving parts makes this meter the ideal device for batching of a wide range of industrial fluids.

Where other metering technologies fail due to the presence of solids in suspension in the process fluid, the 7500S is designed to perform for many years of trouble-free operation with an accuracy of ±0.5% or better.

The built-in Pulse Scaler features easy-to-use rotary switches for batch accuracy compensation, making the 7500S the most straightforward metering system available in the industry.

OPERATION

The 7500S Mag meter is a stainless steel flow tube with an internal isolating lining. Two electromagnetic coils are located outside the flow tube, diametrically opposed to each other and protected by a stainless 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 conductive liquid flows through this magnetic field of 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.

APPLICATION

Because of its inherent advantages over other more conventional technologies, this meter can be used in the majority of industrial sanitary flow applications. Whether the fluid is water or something very viscous, contains a moderate amount of solids or requires special handling, this meter will be able to accurately measure it. Today M-Series meters are successfully being used in many industries including food, beverage and pharmaceutical, handling fluids such as milk, beer, pastes, syrups, and many other hard to measure fluids.
