Bürkert Type 8045 insertion electromagnetic flow meter

Bürkert’s Type 8045 insertion electromagnetic flow meter has been re-engineered.

The meter now has a cut-off feature which is claimed 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 menu-configured digital input has also been added to the meter, allowing control system initiated reset of totalising functions, hold mode go-to, zero-point calibration and other functions. This has been added to facilitate remote control capabilities via site control systems.

An adjustable backlit display for reading and programming in dim conditions has been added. The meter has integrated diagnostics to support local operation, with a simple and conspicuous green/orange/red LED status indication.

The 8045 flow meter is an all-purpose unit with no moving parts, making it suitable for a range of processes, including those with particulate contamination. Processes must be conductive, measuring >20 µs and up to 400 mm process pipe diameter.

Insertion mag flow meters insert 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 are claimed to be advantageous where the accuracy (~0.5%) of a full bore mag flow meter is not required and ~2% accuracy will suffice.

The flow meter is claimed to be easier to install and service than a full bore mag flow meter for this type of application.
