Burkert Type 8045 Insertion Magflow electromagnetic flow meter

Burkert has re-engineered its insertion electromagnetic flow meter Type 8045 to deliver more features for modern processing environments.

The flow meter now has a cut-off feature, designed to optimise use in low-flow applications. This function allows the operator to set a lower limit, under which the measurement value is set as zero. This parameter feeds through to display, totalisers, outputs and downstream process conditions.

A digital input has also been added to the electromagnetic flow meter. This allows control system initiated reset of totalising functions, Hold mode go-to, zero-point calibration and other functions. This feature has been added to facilitate remote-control capabilities, via site control systems. The extension of remote monitoring and control functionality in the magnetic flow meter reflects wider Burkert trends to use expanding mobile technologies for simple and cost-effective process monitoring.

The unit has been updated with an adjustable backlit display for reading and programming in dim conditions. The re-engineered mag flow meter features integrated diagnostics to support local operation, with a simple and conspicuous green/orange/red LED status indication.

The all-purpose unit with no moving parts is suitable for demanding processes including those with particulate contamination. Processes must be conductive, measuring > 20 µs, and up to 400 mm process pipe diameter. Electromagnetic flow meters, also known as magnetic flow meters, use the principles of Faraday’s law with proportional mathematical algorithms to derive flow rate and flow volume.

Insertion mag flow meters poke a sensor finger with integrated electronics into the process flow, rather than replacing a portion of the pipework as full bore mag flow meters do. Insertion mag flow meter types have therefore proven highly advantageous where the extreme accuracy (~0.5%) of a full bore mag flow meter is not required and ~2% accuracy will suffice. Where an insertion mag flow meter may be used, up to 75% cost saving and far simpler installation and servicing result.

The mag flow meter is used extensively in the water treatment industry and water applications, as well as cleaning-in-place (CIP) systems.
