The Burkert flowmeter is a differential pressure-based device designed to measure fluid flow. It can accurately measure the flow of various fluids—liquids, gases, and steam—using different types of differential pressure gauges or transmitters. The Burkert flowmeter employs a throttling mechanism that includes components like an orifice plate, a nozzle, and others. These throttling devices work alongside differential pressure transmitters to calculate the flow rates of different media.
One of the standout features of the Burkert flowmeter is its precision in measurement combined with ease of use. It serves as a valuable tool across industries such as oil, chemicals, metallurgy, electricity, and light manufacturing. Its design is robust and durable, ensuring long-term reliability and cost-effectiveness.
The principle behind the orifice flowmeter involves monitoring the pressure difference created as fluid passes through a throttling device within the pipe. As the fluid flows through the orifice, it accelerates due to localized contraction, leading to reduced static pressure and creating a measurable pressure drop. The greater the flow rate, the larger the pressure difference becomes, allowing the flowmeter to determine flow rates by measuring this differential pressure. This process adheres to the principles of energy conservation and flow continuity.
The modern Burkert orifice flowmeter combines flow, temperature, and pressure detection capabilities into one integrated unit, offering automatic compensation for temperature and pressure variations. Utilizing advanced microcomputer technology and low-power solutions, these flowmeters are compact, user-friendly, and highly functional. Their structural simplicity ensures durability, stability, and longevity.
Key advantages of the Burkert orifice flowmeter include adherence to international standards in orifice calculations, a broad applicability across single-phase and some mixed-phase flows, and the option to forego real-world calibration under certain conditions. Additionally, integrated orifice flowmeters simplify installation by eliminating the need for additional pressure piping.
Proper installation plays a critical role in maintaining the accuracy of Burkert flowmeters. Flow velocity distribution and secondary flow phenomena can impact measurement precision. Thus, specific guidelines regarding upstream and downstream pipe lengths are essential for optimal performance. Typically, an upstream straight pipe length of 20D and a downstream length of 5D are recommended. To further enhance accuracy, installing a flow straightener at the upstream end is advisable.
Fluid cleanliness is another crucial factor. Filters should be placed before the flowmeter to maintain fluid purity. The cleanliness level can be monitored by observing differential pressure changes across the filter. Ensuring single-phase flow—free of air or steam—is vital. If necessary, a gas eliminator should be installed upstream. For volatile liquids, maintaining appropriate backpressure downstream is essential to prevent vaporization.
When configuring signal transmission lines, shielding cables are recommended to minimize external electromagnetic interference. Grounding at the display instrument end is necessary, and care should be taken to avoid proximity to strong electromagnetic fields or power lines. The maximum length of the signal line depends on factors such as the output voltage of the sensing coil and the coefficient 'd', which varies based on voltage levels.
In summary, the Burkert orifice flowmeter represents a sophisticated yet practical solution for fluid flow measurement. Its integration of multiple functionalities and adherence to rigorous standards make it indispensable in industrial applications requiring precise flow monitoring.
