| Racine Vortex offers high-accuracy vortex-shedding flow meters for a number of liquids and gases. The product line is quite unique: by incorporating ultrasonic technology, the meter's bluff body ("strut") has a considerably smaller footprint compared with other vortex-shedding flow meters. This results in very low pressure drop in the system. Meters are available in wafer (in-line, 1/2" to 4" size) or insertion styles (4" line size and higher). This vortex-shedding technology involves no moving parts, and the meters are virtually maintenance-free. Loop-powered gas flow meters offer HART communications, temperature compensation for mass flow measurement and gas flow standardization, CE-mark and optional ATEX hazardous area certification. Liquid flow meters also carry the CE mark. |

The deltaflow flometer is continiously developed and inprooved and we hold several patents on the deltaflow Technology. But we do not only rely on our own know-how %u2013 systec is furthermore co-operating with well known partners sich as the institute for flow mechanics of the University of Erlangen oder the PtB in Braunschweig.
Due to the special probe profile the deltaflow can assure a high level of precision and excellent process viability, even in extreme conditions causing the lowest residual pressure loss. The deltaflow has been installed several thousand times.
Typical Applications are flow measurement of steam, perssurized air, water, liquids, stack gas, flare gas, natural gas.
Typical industries where our deltaflow integrating pitot tubes are used are Manufacturers of power plants, Chemistry, Petrochemistry, Gas- and Oil Exploration, waste water plants.
The program to size and design the deltaflow is very self-explanatory and you can download it for free from our web-page as a Windows file (Windows 9x, 2000 and NT).

The ST75 from Fluid Components International (FCI) is an accurate, no moving parts, direct mass flow measurement and monitoring solution for fuel gases, air, pneumatics, inert and other gas flows within industrial processes. It is available in nine different sizes for direct, in-line installation in line sizes from 1/4 to 2 inch [6 to 51mm].
Combining precision lithography structured platinum RTD detection embedded in FCI's equal mass thermowells with microprocessor electronics and precise actual gas calibration, the ST75 achieves outstanding flow measurement performance. ST75's direct mass flow measurement eliminates costs and space of additional sensors required by inferred technologies.

| The RWG and RWBG Series meters are wafer-style in-line flow meters designed to offer high accuracy gas flow measurements with very low pressure drop. The meters have no moving parts and are virtually maintenance-free once installed. The RWG series is suitable for most gas types. The RWBG series is similar in construction but optimized for low-pressure "wet gas" or "BioGas" applications, typically CH4 + CO2 mixtures. All meters in these series are loop-powered devices with standard HART® communications, CE mark and optional ATEX hazardous area certification. Through the use of an internal INDUSTRIAL RTD and an external pressure sensor specification (optional), the flow meter software will compensate for changes in pressure and temperature, to achieve an accurate mass flow measurement. |

RITTER drum-type gas meters are universally applicable for measuring the volume of flowing gases and are particularly effective when measurements demand the highest precision.
The major advantage and the superiority of volumetric Gas Meters (like Drum-type Gas Meters) over other measurement principles, which determine gas volume using secondary measurable variables such as speed, heat capacity, hot-wire resistance or similar, is that the volume is directly measured. That means that the condition and the composition of the gas has no influence on the measurement accuracy. |
|
Massflow under control
Massflow gas measurement is independant of temperature and pressure, thus controlling a process gas can be stable and reproduceable. Massflow controllers contain a PID-controller and can be driven through norm signal or field bus. Massflow meters are without manufacturers of actuators and are only for measuring massflow. |
