KAMBODA Industrial Modbus DN25 Insertion RS485 Thermal Mass Gas Flow Meter is a reliable and practical choice for professionals working from home who need accurate flow measurement for compressed air, oxygen, and other clean gases. Built with the needs of technicians, engineers, and small lab operators in mind, this thermal flowmeter offers straightforward installation and durable performance. It brings industrial-grade capability into compact systems without complicated setup
This insertion-style meter fits a DN25 port and mounts easily into existing pipelines. Its compact insertion probe reduces disruption to your system and allows for quick deployment. The meter measures gas flow directly using thermal mass sensing technology, which provides fast response and stable readings even at low flow rates. This makes it suitable for monitoring compressed air lines, oxygen supply, inert gas feeds, and similar applications where consistent measurement is important
Communication is flexible. The RS485 Modbus interface gives you remote access to flow data and integrates smoothly with data loggers, PLCs, and SCADA systems. For analog systems, the 4–20 mA output mirrors the measured flow and is compatible with a wide range of controllers and recorders. This dual-output design makes it easy to connect the meter to modern or legacy equipment without extra converters
Accuracy and repeatability are strong points. The thermal sensing element detects mass flow directly, so measurements are not affected by changes in temperature or pressure to the same degree as volumetric meters. This quality is especially beneficial for processes where gas density fluctuates. The KAMBODA flowmeter provides stable data and minimizes the need for frequent recalibration, saving time and reducing maintenance costs
Construction focuses on reliability. The probe and flange are made from corrosion-resistant materials suited to industrial environments. The flange mounting provides a secure, leak-resistant connection that holds up under regular use. Internal electronics are protected against electrical interference, ensuring clean signals even in busy electrical settings
Installation is user-friendly. The insertion probe mounts through the DN25 flange and can be positioned to sample flow at an appropriate depth. For professionals working from home, this simplicity is valuable; you can install the device with basic tools and minimal downtime. Clear wiring for the RS485 and 4–20 mA outputs is provided, and the meter supports common baud rates and Modbus registers, making setup straightforward with existing software
The meter is versatile. It handles a range of flow rates typical for DN25 lines and is suitable for applications such as air compressors, lab gas manifolds, small pneumatic systems, and oxygen supply lines. Use it for leak detection, system monitoring, preventive maintenance, or process control. Its fast response time helps detect transients and brief events that other meters might miss
Maintenance needs are low. The insertion probe can be removed for inspection or cleaning without dismantling large sections of piping. The thermal sensor has a long service life under normal operating conditions. When calibration is needed, it follows standard procedures that most technical users can perform or arrange with calibration services
Safety and compliance are considered. The meter is designed to operate safely with non-corrosive gases like compressed air and oxygen. Appropriate materials and sealing reduce the risk of leaks and contamination. When used within specified limits and installed according to guidelines, it contributes to safe operation of gas systems
For data-driven workflows, the RS485 Modbus output supports continuous monitoring and historical logging. This enables trend analysis, alerts for abnormal conditions, and better decision-making about system operation. The 4–20 mA signal provides a reliable analog option for control loops and simple displays. Together, these outputs ensure the KAMBODA meter meets diverse interfacing needs
The KAMBODA Industrial Modbus DN25 Insertion RS485 Thermal Mass Gas Flow Meter is a practical, accurate, and easy-to-install device for professionals working from home who manage compressed air, oxygen, or similar gas lines. It blends robust construction with flexible outputs and reliable thermal measurement technology. The meter saves time on installation, reduces maintenance, and integrates well with both modern digital systems and traditional analog controls. Choose KAMBODA when you need a trustworthy flow measurement solution that performs well in everyday industrial and lab environments
