KAMBODA’s Thread Type Dn20 Thermal Gas Mass Flow Meter LCD Digital Rs485 Modbus OEM Customizable Stainless Steel is built for professionals working from home who need reliable, accurate gas flow measurement without fuss. This compact meter brings industrial-grade performance into small labs, workshops, and home offices where space is limited but precision matters. It measures mass flow directly, so readings are unaffected by temperature and pressure changes, giving you stable data every time.

The Dn20 threaded connection makes installation simple and fast. You can fit it into existing piping without special adapters. That saves time and reduces the chance of leaks. The stainless steel body is tough and resists corrosion, so the meter works well in a variety of environments. Whether you run a gas line for experiments, remote testing, or small-scale production, this meter stands up to regular use.

The clear LCD display shows readings at a glance. You do not need to hook up a computer to see immediate flow values. The screen is easy to read from a short distance and presents data in a clean, straightforward way. For more advanced setups, the Rs485 Modbus output gives you full digital communication. Integrate the meter into home lab monitoring systems, automation controllers, or custom dashboards. The Modbus protocol is widely supported, so connecting to data loggers or SCADA-lite software is straightforward. If you prefer analog signals or pulse outputs, KAMBODA offers customizable options through OEM services. Choose the outputs and settings that match your workflow. Customization extends to calibration curves, units of measure, and display preferences. This flexibility lets you tailor the device to specific gas types and flow ranges, ensuring accurate performance in your particular application.

Accuracy and repeatability are key features. Thermal mass flow technology measures the actual mass of gas passing through the sensor, eliminating the need for pressure or temperature compensation. This reduces measurement error and simplifies setup. The Dn20 size covers a common range of flows suitable for many home-based professional uses, such as small-scale manufacturing, analytical testing, and HVAC component evaluation. The meter handles a variety of gases commonly used in labs and workshops. KAMBODA provides guidance on compatible gases and offers gas-specific calibration to improve accuracy when needed. The stainless steel construction also helps maintain measurement integrity over time by resisting wear and contamination.

Installation is user-friendly. The threaded connections fit standard fittings, and the meter’s compact length makes it easy to place in tight spots. Wiring the Rs485 connection follows common industry practice, with clear labels for wiring terminals. The user manual is written in simple language and guides you step by step through installation, configuration, and basic troubleshooting. If you need OEM customization, KAMBODA can pre-configure units before shipping, saving you setup time. They can adjust settings like zero point, flow range, and output format to match your exact project needs. This is especially useful for professionals working from home who want a device that integrates smoothly into their existing test setups.

Durability is built in. The meter’s stainless steel wetted parts resist rust and handle typical contaminants better than many alternatives. The electronics are protected against typical electrical noise encountered in home workshops that may share power with tools and other devices. The robust design reduces downtime and the need for frequent maintenance. When maintenance is required, the modular design lets you access sensor elements without removing the entire meter from the line in many cases. That makes servicing quicker and minimizes disruption to ongoing work.

The KAMBODA brand stands for practical, dependable instruments for busy professionals. This Dn20 thermal gas mass flow meter balances real-world ruggedness with the ease of digital integration. It is suited to users who value accurate, traceable measurements but also need straightforward setup and low maintenance. Whether you monitor gas usage, control dosing systems, or validate flow in small production runs, this meter offers a solid combination of features. The LCD gives immediate feedback, while RS485 Modbus opens the door to networked data collection and remote monitoring.

Safety and compliance are also considered. The meter is designed to meet common safety expectations for use with non-corrosive gases in controlled environments. Proper installation and adherence to local standards ensure safe operation. KAMBODA provides documentation to help with compliance and recommends periodic checks to confirm continued accuracy. For professionals working from home who require both dependable data and peace of mind, this meter delivers.

KAMBODA’s Thread Type Dn20 Thermal Gas Mass Flow Meter LCD Digital Rs485 Modbus OEM Customizable Stainless Steel is a compact, accurate, and flexible solution. It combines straightforward installation with robust construction and modern digital communication. The meter suits a range of home-based professional applications, offering reliable mass flow measurement, easy integration, and options for customization to meet specific needs.
