oval gear flow sensor

The oval gear flow sensor represents a sophisticated yet reliable solution for precise fluid flow measurement across various industrial applications. This innovative device operates on a simple yet effective principle: two oval-shaped gears rotate within a chamber, creating precise measurement cavities as fluid passes through. Each rotation corresponds to a specific volume of fluid, enabling highly accurate flow rate calculations. The sensor's design incorporates high-precision manufacturing techniques, ensuring minimal friction and wear while maintaining exceptional measurement accuracy typically within ±0.5% of reading. These sensors excel in measuring medium to high-viscosity fluids and can handle a wide range of flow rates, from 0.5 to 500 liters per minute. The robust construction, typically featuring stainless steel or engineered thermoplastics, ensures durability and chemical compatibility with various fluids. Advanced models include integrated temperature compensation and digital output capabilities, allowing seamless integration with modern control systems. The sensor's bi-directional flow capability and ability to maintain accuracy regardless of fluid viscosity changes make it particularly valuable in process control applications.

New Products

The oval gear flow sensor offers numerous compelling advantages that set it apart in the flow measurement industry. First and foremost, its exceptional accuracy and repeatability make it ideal for applications where precise measurement is crucial, such as in chemical processing or fuel distribution. The sensor's simple mechanical design, with only two moving parts, results in minimal maintenance requirements and extended operational life. This translates to lower total cost of ownership and reduced downtime for maintenance. The sensor's ability to measure various fluid types, from oils to chemicals, provides versatility that eliminates the need for multiple specialized instruments. Its self-draining capabilities and resistance to entrained air ensure reliable operation even under challenging conditions. The compact design allows for easy installation in confined spaces, while the absence of straight pipe run requirements provides flexibility in system design. The sensor's low pressure drop characteristics help maintain system efficiency, reducing energy costs. Additionally, the device's ability to operate in any orientation and its immunity to flow profile disturbances make it particularly user-friendly. The digital output options enable easy integration with modern control systems, while the high turndown ratio ensures accurate measurements across a wide range of flow rates.

Superior Measurement Accuracy and Reliability

Superior Measurement Accuracy and Reliability

The oval gear flow sensor achieves exceptional measurement accuracy through its precisely engineered oval gear mechanism. The design ensures that each gear rotation displaces an exact volume of fluid, resulting in measurement accuracy typically better than ±0.5% of reading. This high precision is maintained across a wide range of operating conditions, including variations in temperature and pressure. The sensor's ability to handle viscosity changes without requiring recalibration makes it particularly valuable in applications where fluid properties may vary. The robust construction and careful material selection ensure long-term stability and repeatability of measurements, making it an ideal choice for critical process control applications.
Versatile Application Compatibility

Versatile Application Compatibility

One of the most significant advantages of the oval gear flow sensor is its remarkable versatility in handling different fluid types and operating conditions. The sensor effectively measures low to high viscosity fluids, from light oils to heavy lubricants, and maintains accuracy across varying flow rates. This adaptability extends to its chemical compatibility, with materials options including stainless steel, PPS, and other engineered materials suitable for aggressive chemicals. The sensor's ability to operate bidirectionally and handle entrained air or gas bubbles without losing accuracy further enhances its application range. This versatility reduces inventory requirements and simplifies specification processes for facility managers and engineers.
Low Maintenance and Cost-Effective Operation

Low Maintenance and Cost-Effective Operation

The oval gear flow sensor's simple yet effective design translates into exceptional reliability and minimal maintenance requirements. The two-gear mechanism represents the only moving parts in the system, significantly reducing wear points and potential failure modes. This simplicity results in extended service intervals and lower maintenance costs compared to more complex flow measurement technologies. The sensor's self-cleaning action during operation helps prevent buildup and reduces the need for regular cleaning. Additionally, the device's ability to operate without external power in mechanical versions provides energy savings and increased reliability in remote locations. The combination of long service life, minimal maintenance requirements, and high accuracy delivers an excellent return on investment for users.
