KAMBODA 4-20mA Swirl Diaphragm Vortex Flowmeter is a reliable and versatile instrument designed for accurate flow measurement of gases, compressed air, liquids, saturated steam, LPG, biogas, and other industrial fluids. Built for durability and ease of use, this flowmeter combines proven vortex-shedding technology with a sensitive diaphragm sensor to deliver consistent, repeatable readings across a wide range of process conditions. Professionals working from home, plant technicians, and field engineers will appreciate its straightforward installation, low maintenance, and clear 4-20mA output that integrates seamlessly with control systems and data loggers
The flowmeter’s core sensing element generates vortices as fluid passes an obstruction. Each vortex sheds at a frequency proportional to flow velocity. The diaphragm detects these pressure fluctuations and converts them into a precise electrical signal. This signal is then processed and output as a standard 4-20mA current loop, making it compatible with most PLCs, SCADA systems, and industrial controllers. The simple analog output avoids complex wiring and provides noise-resistant transmission over long distances. This is especially useful in remote setups or small home-based labs where reliable signal integrity matters
KAMBODA designed this vortex flowmeter to handle both gases and liquids with equal reliability. It measures compressed air and industrial gases with good sensitivity, providing stable readings for process control and energy monitoring. For saturated steam applications, the device tolerates high temperatures and fluctuating conditions while maintaining accuracy. In liquid service, the unit handles water, oils, and other common fluids. LPG and biogas flows are measured accurately as well, supporting applications such as fuel management, energy recovery, and environmental monitoring
Installation is straightforward. The meter requires a straight run of pipe upstream and downstream for stable vortex formation, but KAMBODA provides clear guidelines that minimize space needs. Compact housing and standard flange or threaded connections fit easily into existing piping. The flowmeter is suitable for inline installation in both horizontal and vertical runs, though orientation notes are provided to ensure optimal performance. Once installed, commissioning is quick: power the unit, confirm the output with a simple loop test, and the device is ready to report flow data
Durability is a key feature. KAMBODA uses robust materials for wetted parts to resist corrosion and wear from various fluids, including aggressive gases and hydrocarbons like LPG. The electronics are protected in a sealed enclosure to prevent moisture ingress and dust. This rugged design reduces downtime and lowers lifetime maintenance costs. For professionals working from home or in compact facilities, the low-maintenance nature of this flowmeter means fewer site visits and less routine servicing
Performance-wise, the KAMBODA vortex flowmeter offers a good combination of accuracy, range ability, and stability. It delivers repeatable measurements and can handle pulsating or variable flows commonly found in compressed air systems and biogas plants. The 4-20mA output represents a normalized and easy-to-interpret signal: 4mA typically indicates the low end of the flow range, and 20mA the high end. Users can map this current range to actual flow units using simple calculations or with controller scaling functions. This makes data integration and trend analysis straightforward for energy audits, leak detection, or process optimization
The meter’s response time and frequency characteristics are suitable for most process control loops. It captures changes in flow quickly enough for many control applications, yet provides stable averaged readings that eliminate false fluctuations. This balance helps control algorithms perform better and minimizes unnecessary valve movements or compressor cycling. For professionals running small operations from home, this translates to more consistent outcomes and more efficient use of equipment
Safety and compliance are also addressed. KAMBODA engineers the device to meet common industrial standards for electrical interfaces and pressure containment. When used with proper installation and piping, the flowmeter supports safe operation in systems carrying steam, LPG, and biogas. The design includes provisions for grounding and shielding to reduce electromagnetic interference, which is important when installing the device near other electronics or in electrically noisy environments
Calibration and diagnostics are user-friendly. The flowmeter can be zeroed and scaled through accessible adjustments, and basic diagnostics are available via the 4-20mA signal behavior. If the loop current is outside expected bounds, technicians can quickly identify wiring or sensor issues. For more advanced needs, KAMBODA offers optional configuration tools and documentation to help users fine-tune settings for specific fluids or process conditions
Energy efficiency is an added benefit. By accurately measuring compressed air and gas consumption, businesses can identify waste and optimize systems, reducing operating costs. In biogas facilities, reliable flow data supports better control of digester processes and gas upgrading systems. For steam systems, knowing exact saturated steam flow helps balance heat delivery and improve boiler efficiency. The KAMBODA vortex flowmeter provides the actionable data needed to drive these improvements
The KAMBODA 4-20mA Swirl Diaphragm Vortex Flowmeter is a practical, dependable choice for measuring gases, compressed air, liquids, saturated steam, LPG, and biogas. It blends proven vortex technology with a diaphragm sensor to produce a robust, low-maintenance instrument that integrates easily with existing control systems via a standard 4-20mA output. Its durable construction, ease of installation, and reliable performance make it suitable for professionals working from home, small plants, and industrial facilities seeking accurate flow measurement and better process control
