1.1 minutes to understand the difference between balanced flowmeter and orifice flowmeter
The core difference between balanced flowmeter and orifice flowmeter lies in their working principle, structural composition, performance characteristics, and application scenarios, as follows:
1. Working principle Balanced flowmeter: designed based on the energy balance positive roll principle, it belongs to a new type of differential pressure flow instrument. Through unique Reynolds number design, increased thickness of throttling components, and high-precision machining, the fluid flow performance approaches that of a Venturi tube, resulting in a concise structure and significantly improved performance. Orifice flowmeter: It calculates the flow rate by measuring the pressure difference generated when the fluid flows through the orifice plate. The pressure difference is proportional to the flow rate and is a typical conventional differential pressure flowmeter.
2. Structure and Composition Balance flowmeter: It consists of a pipeline and a flowmeter body, and contains a porous disk throttling rectifier (balance flow sensor) inside.
. The size and distribution of the holes on the disc are customized based on special formulas and test data, known as function holes, to ensure a stable flow field when the fluid passes through. Orifice flowmeter: It consists of a circular plate and a central hole. The circular plate is installed at the center of the pipeline, and the hole is located at the center of the plate surface. The types include standard type, notch type, or convex type, with a simple and fixed structure.III. Performance Characteristics Balance flowmeter: High temperature and high pressure resi
Fourth, Application Scenarios: Balanced flow meters are preferred for industries such as petrochemicals, power, and pharmaceuticals, especially suitable for scenarios that require high-precision and long-term stable measurements (such as trade settlement and process control).
. Orifice flowmeter: commonly used in civilian fields such as tap water, gas, and air conditioning, and also suitable for process control and basic measurement in industrial sectors such as petroleum and chemical industries. Summarizing that balanced flow meters have better performance (such as energy saving, accuracy, and straight pipe requirements), but higher costs; Orifice flow meters are characterized by their simplicity, low cost, and strong versatility. When making a selection, it is necessary to comprehensively evaluate factors such as measurement accuracy requirements, wor
