Burkert 8026 Insertion Rotor Flow Meter 561860

The Burkert 8026 insertion rotor flow meter (model 561860) is an ELEMENT design. This Burkert 8026 flow meter features a compact design and is suitable for a variety of applications (water, wastewater monitoring, chemical treatment, etc.), especially for liquids without solids.

The Burkert 8026 turbine flow meter is available with: - 2 outputs: NPN output and 4...20 mA (2-wire) - 3 outputs: NPN and PNP outputs and 4...20 mA (2-wire) - 4 outputs: NPN and PNP outputs and two 4...20 mA (3-wire) The Burkert 8026.

insertion rotor flow meter can convert measurement signals to display different values on different devices (if a display/configuration module is installed).

Output signals can be calculated after connecting via one or two M12 connectors. With one or two outputs, the Burkert flow meter can control solenoid valves, activate alarm systems, and establish one or two control loops.

The Burkert 8026 turbine flow meter features: PN10, configurable for pipe diameters from DN20 to DN400; outputs include one or two transistor outputs and one or two 4...20 mA current outputs; a detachable backlit display/module displays instantaneous flow and total flow via two flow accumulators; and an automatic.

calibration function that allows checking all output signals without flow requirements.

German Burkert flow meters come in many types, with vortex flow meters and elbow flow meters being particularly effective for steam measurement. Therefore, accurate measurement is crucial, and proper selection of the flow meter is essential. directly related to product selection.

The Burkert 8026 insertion rotor flowmeter (model 561860) from Germany can measure flow rates and eddies, but with the limitations of measurement error, this method of measurement is widely used and can be applied to measure high-temperature and high-pressure fluids. It can also be used for dirty media.

Some instruments also measure flow rates.

The working principle of the Burkert rotor flowmeter is as follows: The Burkert rotor flowmeter consists of two parts: a tapered tube that gradually widens from bottom to top; and a rotor placed inside the tapered tube that can move freely up and down along the tube's centerline.

When measuring the flow rate of a fluid, the fluid flows in from the lower end of the tapered tube.

The fluid flow impacts the rotor, generating a force on it (the magnitude of this force varies with the flow rate). When the flow rate is large enough, the generated lift forces the rotor, raising it.

Simultaneously, the fluid being measured flows through the annular cross-section between the rotor and the conical tube wall.

At this point, three forces act on the rotor: the dynamic pressure of the fluid on the rotor, the buoyancy of the rotor in the fluid, and the rotor's own weight.

When the Burkert flowmeter is installed vertically, the rotor's center of gravity coincides with the axis of the conical tube, and the three forces acting on the rotor are all parallel to the tube axis.

When these three forces reach equilibrium, the rotor floats smoothly at a certain position within the conical tube. For a given rotor flowmeter, the rotor's size and shape are fixed; therefore, its buoyancy and weight in the fluid are known constants.

Only the dynamic pressure of the float on the fluid varies with the incoming flow velocity.

Therefore, when the incoming flow velocity increases or decreases, the rotor will move upward or downward, and the corresponding flow cross-sectional area will change until the flow velocity reaches the equilibrium velocity, at which point the rotor stabilizes at the new position.

For a given rotor flowmeter, the rotor's position within the conical tube corresponds one-to-one with the flow rate of the fluid passing through the conical tube. Precautions for the use and maintenance of BURKERT turbine flow meters:

• Before putting the BURKERT turbine flow meter into operation, the instrument coefficient must be set, and a careful check must be performed to ensure that the flow meter wiring is correct and the grounding is good before powering on;
• The BURKERT flow meter should be cleaned, inspected, and recalibrated regularly. The condition of the filter can be judged by the increase in the pressure difference between the inlet and outlet pressure gauges. If blockage occurs, it should be cleared in time;
• For BURKERT turbine flow meters used for trade settlement, regular calibration is necessary to ensure accurate and reliable measurement.
