deltaflowC

Differential pressure flow meter
for precise gas massflow measurement

Differential pressure (dp) flow meter: The deltaflowC from systec Controls is a revolutionary gas flow meter that operates on the advanced differential pressure (dp) principle for measuring gas massflow. This device stands out as possibly one of the smallest and fastest multivariable transmittes for real-time, precise differential pressure flow metering of gas massflow. It 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 deltaflowC measures gas massflow, performing 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 deltaflowC 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: Differential Pressure Flow Meter, Gas Massflow and Volume Measurement, as well as Pressure and Temperature Measurement in One Device

The differential pressure flow meter deltaflowC 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 deltaflowC is the ideal solution for differential pressure flow metering, including applications as a compressed air meter and gas massflow meter. It is available in two models: an insertion probe for pipes starting from 28mm inside diameter (1in) 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.

deltaflowC 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. Using a digital bus, it includes all measured and calculated physical


Gas Flow Meter deltaflowC: Advantages Over Thermal Mass Flow Meters

The deltaflowC offers multiple advantages, including compared to thermal mass flow meters. It compensates for the effects of pressure and temperature on flow measurement, offering users a compensated gas massflow. Unlike thermal mass flow meters and other gas massflow meters, the deltaflowC is remarkably less sensitive to surface fouling by e.g. oil films, condensates and particles... The deltaflowC 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 deltaflowC 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 thermal mass flow meters, the deltaflowC 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.

Easy Parameterization of dp Gas Flow Meters - even for high flow rates, high temperatures, etc.

The deltaflowC is user-friendly and makes field parameterization very easy. Users can define process parameters using the free Excel design tool and then input three specific parameters on the deltaflowC's display in just moments. It is highly resistant to contamination and oil films, operates with minimal maintenance and drift. It is also suitable is suitable for extensive ranges of flow, temperature, and pressure.

Suitable for a Wide Range of Diameters

The deltaflowC is a universal solution, offering standardized installation lengths for all pipelines and ducts. This dp gas mass flow meter has a simple, standardized design and is readily available from stock, making it highly convenient for various applications. It comes standard with analog outputs (4..20mA, 0..10VDC) and can be optional supplied with pulse output, CAN, and Mod-Bus. OEM and private label solutions are available on request.
