Clamp-on ultrasonic flowmeters
The SITRANS F US clamp-on ultrasonic flow technology offers several advantages, number one being the utilization of external transducers. These are quickly and easily mounted on the outside of the pipe, making them the perfect choice for retrofit applications and applications where corrosive, toxic or high pressure liquids and gases rule out the option of cutting the pipe.
With the use of the WideBeam technology, clamp-on flowmeters from Siemens have proven their superiority in both the field and the lab. They offer several benefits such as measurement of practically any liquid and gas; performance unaffected by viscosity, flow rate, pipe size, solids and aeration content; high accuracy and repeatability through automatic temperature compensation and zero drift correction; and installation flexibility on pipe sizes up to DN9140 (360 inches). They are available in six families: two geared towards general industry solutions and four tailored to energy, liquid hydrocarbon, gas and portable installations.
Combine this with flexible configuration options that allow you to either customize your flowmeter or to order complete systems, you can rest assured that we have the right solution for you.

Portable ultrasonic flowmeter FLUXUS F601 is ideal for troubleshooting, plant optimisation and for control of permanent meters.
Features
* Wide application range thanks to the ability of the transmitter to work with shear wave AND lamb wave transducers at all frequencies
* A single pair of shear wave transducers fits a wide pipe diameter range
* Rapid installation without process interruption
* Bi-directional measurement
* High measurement dynamics
The FLUXUS ® G ultrasonic flowmeters use the proven "clamp-on" technology. The flow transducers are simply clamped onto the outside of the pipe. The measurement can hence be put into operation without cutting into the pipe and without production stop. The installation costs are low, retrofitting is not a problem.
Since the transducers are not in contact with the gas, there is no possibility of chemical attack. There are no moving mechanical or pressure loaded parts and thus no wear an tear. FLUXUS G is ideal for measurements at high pressures or on lines with pressure peaks.
Two transducer types for a uniquely wide application range
All FLUXUS® G transmitters support both lamb wave and shear wave transducers at all transducer frequencies. In this way the measuring system can be optimized to even the most demanding applications.
The Lamb wave transducers are ideal for measurement at high flow velocities, in natural gas pipelines for example, or at low pressures, amongst others in compressed air circuits. The shear wave transducers cover a wide range of pipe diameters and wall thicknesses. They are the best choice for mobile measurement or for high pressure systems.

General description :
M 200 C Rotameters are gas flow meters that can regulate flow. They consist of a base plate, measuring tube holders, a dosing valve and a measuring tube. The size and type of the measuring tube varies according to the flow range and gas type.
The dosing valve is designed for accurate regulation of the desired gas flow which is read by means of the measuring tube.In order to ensure uninterrupted operation when dosing smaller amounts of gas (up to 25 g/h), additional filtration has been installed in the system.
Dosing valves are made of technically pure silver. Acicular fabrication ensures high precision of dosing.

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.

Gas density controllers
These operate mechanically. The density of the sample gas is compared via a bellows system with the gas density in a reference gas chamber. If the density of the sample gas alters, the bellows system actuates one or more micro switches. Gas density controllers function independent of any power supply.
Trafag gas density controllers are employed internationally in gas-insulated, high-voltage switchgear in power distribution networks. Their performance record is worldwide is unique. Even at climate-related temperature fluctuations of over 135°C, they provide precise measurement results and function reliably and maintenance-free. They are therefore to be found all around the world, in the ice-cold polar regions or under the blazing desert sun.
Gas density sensors
function electronically. The consistent resonant frequency of a quartz oscillator under vacuum is compared with the resonant frequency of an identical quartz situated in the sample gas. The difference in the resonant frequency is proportional to the density of the sample gas. This difference is processed into a digital or analogue output signal.
