Rossonix Co., limited, established in 2011, is a professional trading company specializing in high-quality flow measurement instruments. With an annual export value of US$5-10 million and a global market presence spanning North America, Europe, Asia, and Oceania, we are committed to delivering reliable and cost-effective solutions for industrial fluid monitoring. The AUTO FLOW Differential Pressure Area Flow Meter ALT-N-10-1-A1 is a precision pipeline fluid flow indicator device designed to provide accurate, direct-reading flow measurements for a wide range of media, including liquids, gases, and steam. Its robust construction and simple operation make it an ideal choice for applications where reliability and ease of use are paramount.
This flow meter operates on the well-established differential pressure area principle, where a variable-area orifice creates a pressure drop proportional to the flow rate. The resulting differential pressure displaces a float or piston, which is directly coupled to a visual indicator, allowing operators to read the flow rate instantly without the need for external power or complex electronics. This inherent simplicity reduces maintenance requirements and enhances long-term stability.
Key features of the ALT-N-10-1-A1 include:
Direct Flow Indication: No external power source needed – the mechanical indicator provides a clear, continuous reading of the flow rate.
Wide Applicability: Suitable for clean liquids, gases, and low-viscosity steam, with optional materials for corrosive media (e.g., 316 stainless steel, PTFE lining).
High Pressure & Temperature Resistance: Standard models handle up to 10 MPa and 200°C, with higher ratings available upon request.
Simple Installation: Available in flanged or threaded connections to match existing piping systems, and the compact design saves space.
Low Maintenance: No moving electrical parts, reducing the risk of failure in harsh environments; the float mechanism is self-cleaning for most applications.
Customizable Options: Choose from different scale ranges (e.g., 0-100 L/min, 0-500 m³/h), connection sizes (DN15 to DN200), and indicator materials (aluminum, stainless steel).
The following table summarizes the typical technical specifications of the ALT-N-10-1-A1 differential pressure area flow meter. Please note that all parameters are customizable to meet specific process requirements.
| Parameter | Standard Range | Remarks |
|---|---|---|
| Measured Media | Liquid, Gas, Steam | Viscosity |
| Accuracy | ±1.0% of full scale | Higher accuracy available |
| Pressure Rating | Up to 10 MPa | Customizable to 25 MPa |
| Temperature Range | -20°C to +200°C | Extended range up to 400°C |
| Connection Size | DN15 – DN200 | Flange or threaded |
| Wetted Materials | 304/316 SS, Carbon steel | PTFE, Hastelloy optional |
The ALT-N-10-1-A1 is particularly advantageous in applications where power supply is unavailable or unreliable, such as remote pipelines, offshore platforms, and chemical processing plants. Its mechanical design ensures zero drift and consistent performance over time, reducing the need for recalibration. Additionally, the indicator can be scaled in any engineering unit (e.g., GPM, L/min, m³/h) according to customer requirements.

Frequently Asked Questions (FAQ)
Q: What types of fluids can the ALT-N-10-1-A1 measure?
A: It is suitable for clean liquids (water, oil, chemicals), gases (air, nitrogen, natural gas), and low-viscosity steam. For corrosive or high-viscosity fluids, please consult our technical team for material and design options.Q: Is the flow meter suitable for high-pressure applications?
A: Yes, the standard model supports up to 10 MPa. Custom versions can handle up to 25 MPa or higher depending on the connection and material selection.Q: Does the meter require an external power supply?
A: No, the ALT-N-10-1-A1 is a purely mechanical flow indicator. It operates on the differential pressure principle and provides a direct visual reading without any electrical power.Q: What is the typical accuracy of this flow meter?
A: The standard accuracy is ±1.0% of full scale. Higher accuracy (e.g., ±0.5%) is available as an option.Q: Can the indicator scale be customized?
A: Absolutely. The scale can be printed in any engineering unit (L/min, m³/h, GPM, etc.) and with any range you specify. Please provide your desired flow range and unit when ordering.Q: How do I install the flow meter?
A: It can be installed either horizontally or vertically, but the orientation must be consistent with the indicator design. Flanged or threaded connections are available to match your pipeline. Detailed installation and maintenance instructions are provided with the product.Q: What maintenance is required?
A: Minimal maintenance is needed. Periodically check for any blockage or contamination in the float mechanism. For clean media, the float is self-cleaning. In harsh environments, occasional cleaning of the sight glass is recommended.Q: Do you offer customization for special materials or connections?
A: Yes, we offer a wide range of customization including wetted materials (316L SS, PTFE, Hastelloy), connection sizes, pressure ratings, and special coatings. Contact us with your specific requirements.
