Gas flow meter deltaflowC
Measuring gas mass flow via differential pressure
Gas flow meter deltaflowC2 at a glance
The deltaflowC2 from systec Controls is a revolutionary gas mass flow meter that operates on the advanced differential pressure (dp) principle for measuring gas massflow. This device is possibly one of the smallest and fastest multivariable transmitters for real-time, precise differential pressure flow metering of gas massflow. This gas flow meter masterfully integrates highly sensitive sensors for differential pressure, static pressure, and temperature, along with a powerful processor, all compactly assembled on a minimal surface area.
The deltaflowC2 performs up to 2,000 measurements per second, and is capable of processing and filtering the physical variables dp, pabs, and T ultra-fast. This provides users with accurate gas massflow signals and concurrent pressure and temperature readings, making the differential pressure flow meter deltaflowC2 not only suitable for measuring stationary flows but also for managing high measurement dynamics and pulsations found e.g., in compressors or combustion engines.
3 in 1: Gas Flow Meter, measuring Gas Massflow and Volume, as well as Pressure and Temperature in one device
The gas flow meter deltaflowC2 offers a comprehensive solution, providing gas massflow measurements in a single device while also monitoring process temperature and pressure. As a gas flow meter, it is specially designed for the measurement and control of ventilation systems and other gases in pipes and ducts. The deltaflowC2 is the ideal solution for differential pressure flow metering, including applications as a compressed air meter and gas massflow meter.
Details of the gas flow meter deltaflowC2
Differential pressure flow meter deltaflowC2 is available in two models: an insertion probe for pipes starting from 28 mm inside diameter (1 in) and a screw-in venturi for smaller pipes with diameters ranging from 3/4 to 1.5 inches. Installation is straightforward, with the probe version requiring just a connection piece on the pipe, and the venturi version easily screwed into a pipe section.
Gas flow meter deltaflowC2 has analog outputs (4..20mA and 0..10VDC), a pulse output, CAN-bus and Modbus RTU. It fits perfectly into all electrical environments. The analog outputs can not only be used to transmit the gas massflow, but also for differential pressure (dp), temperature or pressure (pabs) signals.
Differential Pressure Flow Meter vs. Thermal Mass Flow Meter
The differential pressure flow meter deltaflowC2 offers multiple advantages, also in comparison to a thermal mass flow meter. It compensates for the effects of pressure and temperature on flow measurement, offering users a compensated gas massflow. Unlike a thermal mass flow meter and other gas mass flow meters, the deltaflowC2 is remarkably less sensitive to surface fouling by e.g. oil films, condensates and particles...
The deltaflowC2 gas flow meter is virtually maintenance-free, low on drift and suitable for a wide range of flow rates, temperatures, pressures and gases, including compressed air. Furthermore, the deltaflowC2 gas flow meter fits almost all pipelines and ducts with just one installation length, making it quickly available and easy to stock. In contrast to a thermal mass flow meter, the deltaflowC2 differential pressure flow meter can be easily adapted to various gases without the need for recalibration. The gas massflow meter can simply be recalculated to any gas using the physical principles described in the ISO 5167.

Frequently Asked Questions about the Gas Flow Meter deltaflowC
Differential pressure flow measurement has enormous advantages: it is highly accurate, very robust and delivers precise measurement results at all times, whether for gases, compressed air or other media. deltaflowC measures the gas mass flow accurately at all times, even under difficult environmental conditions.
In short, a thermal flow meter is less robust and much more expensive to purchase, maintain and operate. The robust deltaflowC gas mass flow meter is insensitive to contamination and compensates for pressure and temperature fluctuations. It requires virtually no maintenance and can be fitted to almost all pipes and ducts with just one pipe length.
This means it can be delivered very quickly.
Another useful feature is that the deltaflowC can be easily converted to any gas. A thermal flow meter must be recalibrated each time the gas is changed.
deltaflowC is therefore clearly superior to a thermal flow meter.
deltaflowC is ideal for industrial gas applications, such as compressed air, natural gas, biogas, CO₂ and exhaust air, wherever a durable, maintenance-free gas mass flow meter is required.
Yes, deltaflowC can also measure compressed air flow. In addition to measuring mass flow, it also provides data on process temperature and pressure. It is also virtually maintenance-free.
Depending on the application, the deltaflowC gas flow meter has an accuracy of up to ±1–2% of the measured value. This level of accuracy is similar to that of a thermal flow meter.
However, if there are pressure and temperature fluctuations, a differential pressure flow meter provides a significantly more stable measurement than a thermal flow meter.
Yes. Unlike thermal flow meters, differential pressure measurement with the deltaflowC is insensitive to condensates, moisture and dust, making it ideal for harsh industrial environments.
Thanks to the differential pressure principle, the deltaflowC provides precise gas flow data at all times, even in the presence of high measurement dynamics, contamination or pulsations.
deltaflowC can also measure the mass flow up to 2000 times per second thanks to its combination of highly sensitive sensors and a powerful processor, providing values for differential pressure (dp), static pressure (pabs) and temperature (T) in near real time.
The deltaflowC gas flow meter is available in two variants:
- As a plug-in probe for diameters from DN32
- As a screw-in venturi for smaller pipes with diameters between 0.75 and 1.5 inches.
Both versions are easy to install; a pipe connection is sufficient for the probe. The Venturi meter is screwed directly into a pipe section.
Depending on the version, the deltaflowC can be used at temperatures of up to 180° C and pressures of up to 16 bar, making it suitable for many industrial gas applications.
Standard: 4–20 mA; optional: Modbus RTU or HART for easy integration into control systems.
