JC-P
JIECHUANG
Overview
The JC-P type balanced flow meter is a breakthrough in flow measurement technology, providing exceptional improvements over traditional throttling devices. Unlike conventional flow meters with a single aperture that can disrupt the ideal flow state, the balanced flow meter employs multiple functional apertures that optimize and stabilize the flow, resulting in an ideal fluid flow state. This innovation maximizes the advantages of differential pressure flow meters, offering more precise and reliable measurements.
Widely used across industries such as petroleum, chemical, metallurgy, natural gas, and water treatment, the balanced flow meter is capable of handling a broad range of fluid types, including complex media like two-phase flows, mixed gases, and cryogenic gases. It stands as a revolutionary advancement in fluid measurement technology, providing high precision and reliability in even the most demanding industrial applications.
Operating Principle
The balanced flow meter operates on the same fundamental principles as traditional differential pressure flow meters. The core principle relies on the fact that in an ideal fluid, the flow rate within a sealed pipeline is proportional to the square root of the differential pressure. By measuring the differential pressure and applying Bernoulli’s equation, the flow rate can be accurately calculated.
Equipped with a multi-ported orifice plate, the balanced flow sensor effectively rectifies and balances the flow. Each port is carefully designed and distributed based on specific formulas and testing data. The fluid passes through these functional apertures, which eliminate turbulence and ensure that the flow is as ideal as possible. This not only improves accuracy but also enhances the performance of differential pressure flow meters in complex or varying conditions.
Product Features
High Linearity and Repeatability
The balanced flow sensor features a symmetrical multi-port structure that greatly reduces turbulence, vibrations, and signal noise. This optimized flow field stabilizes the readings, improving linearity by up to 5 to 10 times compared to traditional orifice plates. The repeatability of measurements is enhanced by 54%, achieving 0.15% accuracy. These performance metrics classify the balanced flow meter as a high-end flow measurement instrument, offering industry-leading precision.
At a 5:1 turndown ratio, the linearity is ±0.3%.
At a 10:1 turndown ratio, the linearity is ±0.5%.
At a 30:1 turndown ratio, the linearity is ±1.0%.
Low Straight Pipe Length Requirements
Due to the stable flow field and twice faster pressure recovery compared to orifice plates, the balanced flow sensor significantly reduces the need for long straight pipe lengths. Typically, it requires only 3D upstream and 1D downstream straight pipe lengths, with minimum cases requiring less than 0.5D. This design saves a significant amount of pipeline space, making it especially beneficial in applications with specialized materials or limited space.
Reduced Permanent Pressure Loss
The symmetrical multi-port balanced design helps reduce turbulent shear forces and vortex formation, effectively lowering kinetic energy loss. This results in a 2.5 times reduction in permanent pressure loss compared to traditional throttling devices under similar conditions, which leads to significant energy savings and lower operational costs.
Dirt Resistance and Reduced Clogging
The design of the balanced flow meter minimizes dead zones, which reduces the likelihood of clogging when measuring dirty media. The multi-port symmetrical structure ensures smooth flow through various complex media like slurries and viscous fluids, maintaining high accuracy even in challenging environments.
Direct Orifice Plate Replacement
The balanced flow meter is designed to be a direct replacement for traditional orifice plates, making it easy to install without requiring any changes to the piping or related instruments. This feature makes it an ideal solution for energy management systems (EMS) upgrades, allowing for seamless transitions without disrupting existing operations.
Wide Flow Measurement Range
The balanced flow meter can measure flow rates as low as sonic speeds. With the ability to handle Reynolds numbers from 200 to over 10⁷ and β values ranging from 0.25 to 0.90, it offers an extensive measurement range. This capability makes it suitable for a wide variety of applications, including high flow rate and low flow rate environments, ensuring accurate measurements in both high viscosity and low viscosity fluids.
Excellent Long-Term Stability
With no moving parts, the balanced flow meter is highly durable and provides exceptional long-term stability. The design minimizes friction between the fluid and the throttling element, ensuring that the β value remains constant over time, even in harsh operating conditions. This makes it a reliable choice for applications that require consistent, long-term performance.
High Temperature and Pressure Capability
The balanced flow meter is capable of operating at temperatures up to 450°C and pressures as high as 25 MPa. This makes it suitable for high-temperature and high-pressure applications in industries such as petroleum, chemical processing, and natural gas measurement, where extreme conditions are common.
Measurement of Complex Media
Thanks to its innovative design, the balanced flow meter excels at measuring complex media such as two-phase flows and mixed gases (e.g., biogas, coal gas) and even cryogenic gases like LNG, liquid nitrogen, and liquefied petroleum gas (LPG). This versatility makes it ideal for a wide range of industrial sectors, including energy, chemicals, and food & beverage.
Cost-Effective: By reducing pressure loss and energy consumption, the balanced flow meter offers significant cost savings over time.
Versatile Measurement: Its ability to handle a wide variety of fluids and gases makes it suitable for industries ranging from oil and gas to food and beverage and water treatment.
Efficiency: The balanced design ensures that the flow is rectified and stabilized, leading to more accurate flow measurements with less interference from external factors.
Low Maintenance: The lack of moving parts reduces the need for frequent maintenance, lowering the total cost of ownership.
The JC-P balanced flow meter represents a cutting-edge solution for industries requiring precise flow measurement under high temperature and high pressure conditions. Its innovative design and superior performance make it an excellent choice for companies looking to optimize their flow measurement processes and reduce operational costs. With its ability to handle a variety of complex media, high accuracy, and exceptional long-term stability, the balanced flow meter is a must-have tool for modern industrial applications.
