What are the differences between vortex flowmeter and balance flowmeter? When to choose vortex street and when to use balance? The main differences between vortex flowmeter and balance flowmeter are measurement principle, applicable medium, pressure loss characteristics, straight pipe section requirements, and cost; When choosing, if measuring a clean single medium and pursuing low maintenance costs, vortex flowmeter is preferred; If the working conditions are complicated, the requirements for the straight pipe section are low, and a high initial investment is accepted, then a balanced flowmeter should be selected. The difference between vortex flowmeter and balance flowmeter. Measurement principle of vortex flowmeter: Based on the Karman vortex principle, when the fluid flows through a non streamlined vortex generator, two regular vortices will be alternately generated on both sides. The frequency of the vortices is proportional to the flow velocity of the fluid, and the flow rate can be calculated by measuring the vortex frequency. Balanced flowmeter: It belongs to differential pressure flowmeter, which uses a unique structural design to generate a stable differential pressure when the fluid passes through the flowmeter, and measures the flow rate using the functional relationship between differential pressure and flow rate. Applicable medium vortex flowmeter: suitable for measuring single media such as clean gases, steam, or liquids, and the measurement results are basically not affected by factors such as fluid density, pressure, temperature, and viscosity. Balanced flowmeter: capable of measuring various media, including gases, liquids, and steam, with strong adaptability to media, especially suitable for flow measurement at high temperatures and pressures. Pressure loss characteristics of vortex flowmeter: With low pressure loss, it has less resistance to the fluid during the measurement process, which can reduce energy loss and lower operating costs. Balanced flowmeter: By optimizing the design, it achieves high and stable differential pressure with lower permanent pressure loss under short straight pipe conditions, further reducing pressure loss compared to conventional throttling devices. The straight pipe section requires a vortex flowmeter: there are certain requirements for the straight pipe section, and generally a longer straight pipe section is needed upstream to ensure stable fluid flow and measurement accuracy. Balanced flowmeter: reduces the requirements for straight pipe sections and can achieve accurate flow measurement even under shorter straight pipe conditions, making it suitable for applications with limited installation space. Precision and Range Vortex Flow Meter: With high precision and wide range, it can meet the measurement needs of different flow ranges and performs excellently in the field of trade settlement. Balanced flowmeter: improves measurement accuracy, expands range, and can more accurately measure the flow rate of media at different flow rates. Maintenance and reliability of vortex flowmeter: It has a simple structure, no moving parts, strong combustible branches, low maintenance, good long-term stability, and can reduce maintenance costs and workload for enterprises. Balanced flowmeter: solves the problems of easy blockage and frequent maintenance of standard throttling devices, with convenient installation, safety and reliability, high temperature resistance, and strong universality, reducin
