A centrifugal pump draws an incompressible fluid (water) from a buffer tank and distributes it via a membrane control valve and rotameter to two pipe sections with different flow sensors: a paddle flow meter, electromagnetic flow meter, and vortex flow meter on one section; a Venturi tube and normalised orifice plate (both connected to a differential pressure sensor) on the other. The fluid circulates in a closed loop back to the buffer tank.

One tank with drain and draw-off point; one three-phase stainless steel centrifugal pump.
One variable speed drive allowing pump speed regulation based on a flow setpoint from one of the flow meters.
One rotameter.
One pipe section with selector valve containing: a paddle flow meter (for low-viscosity liquids) — a plastic vane turbine rotates under the effect of flow; a detector transmits the rotational speed, and the associated electronics convert the frequency to instantaneous flow; a vortex flow meter — a body inserted in the flow generates downstream vortices whose shedding frequency is proportional to volumetric flow; transmitter with 4–20 mA output and local display.
One pipe section with selector valve containing: a Venturi tube, DN25, in acrylic with U-tube manometer and differential pressure sensor port; a normalised orifice plate, DN25, in acrylic with U-tube manometer and differential pressure sensor port; a differential pressure sensor, 4–20 mA output, connected to an indicator with square-root extraction for flow determination.
One vertical pipe section with an electromagnetic flow meter for conductive liquids — a voltage induced in the fluid is picked up by two measurement electrodes and the signal converter determines fluid velocity; transmitter with 4–20 mA output and local display.
One IP55 sealed electrical cabinet containing: a lockable isolator, power indicator light, key-operated emergency stop, variable speed drive; a 4-position selector to choose the flow meter input to the controller.
