Innovative measuring technique with ultrasonic Refers and Explanations to applications and potentially applications from the industries: Oil & gas Natural gas extraction and storage Fastidious uses of level measurements are measurements of receivers with medium mixtures in the oil and gas industry. Light and heavy hydrocarbons, from the gas oil to the wax, oils from compressors, in addition, additives for water connection such as glycol or methanol and water can be a component of the medium which can be measured. Where procedure admitted, how float switches and capacitive probes failed or cause with certain operating conditions faulty measurements, can be worked favourably with ultrasonic. Radar requires an antenna in the gas area of the container and is gas-tight only up to certain maximum pressures (64 bar). Conventional ultrasonic is for pressures off approx.. 4 bar no longer applicably. For measurements of containers under vacuum ultrasonic systems from above are not usable. Measurements with ultrasonic through the container wall are here an interesting alternative. Measurements with ultrasonic by the container wall do not require openings, since the ultrasonic transducers couple directly on the wall. No changes at the existing receivers are necessary. Without putting out of operation of the components new measuring points can be installed, since no emptying of the containers is necessary. Since likewise no weldings must be accomplished, all safety-relevant permissions remain. With measuring procedures by the container wall all problems are gone around with pressure tight executions for sensors. Different dielectric constants for condensate mixtures from hydrocarbons and water, the capacitive procedures sensitively disturb are without influence on the result of measurement. Hanging floats, that make measurements with magnet flaps useless, can be replaced. Existing bypass pipes are equipped additionally with the system for measurement. The make of the bypass pipes is not thereby of importance. For nearly each conventional measuring technique there is replacement without profound change at the existing containers and technological mechanisms. Often only the thermal insulation at a part of the container is to be removed. Existing flanges can be modified for certain measuring tasks. Potential application type result at all preparation and drying units for natural gas Continuous level measurement of lying and standing containers loaded by pressure. Level measurement of condensate separators of gas dressing plants (gas filter separators) Level measurement of condensate collecting pipes from eddy tubing separator to hydrocarbon the dew point lowering, gas more dry on oil/gas fields, where typical joules Thomson valves are used and on upper day plants for natural gas storage with the drying process of the natural gas. In plants for glycol regeneration on upper day plants of underground storage. Level measurement at compressor oil reservoirs on natural gas compressor plants. Additional assembly of existing magnet flap indicators With bypass magnet flap indicator the indicator locally with an independent and maintenance-free a level regulation or measurement can be equipped in simple way. Altogether very favourable solutions result regarding the necessary costs. Safety-relevant the new measuring points that can be available parallel switched and be increased thus by redundancy the availability. From each other the independent effect principles ensure also in case of failure of a system the plant safety. Condensate separator in natural gas nets Level-control of condensate collectors of slidegate valve and distribution systems The absolutely maintenance-free enterprise of the border condition switches by the container wall offers optimal protection of the plants on a manless distribution systems in connection with a remote data communication. The level or border condition data can be transmitted thus together with the remote maintenance and monitoring of stop valves into natural gas pipelines. The data communication can take place by means of radio modem in the GSM net. Diagnostig Tools can be initiated problem-free over GSM or fiber cable. Subsequent changing of measuring point parameters makes remote monitorings possible. Increasingly frequently stop valves are automated also outside by compressor or memory act ions. Off the land development the out and/or re-equipment is connected with an electric drive operated by remote control due to the missing EVU connection usually with substantial costs. An automation concept independent of the current and telecommunications net is made possible by the employment of the Photovoltaik as well as the GSM technology also in hard-to-travel areas. Odoriermittelstationen Level control and continuous level measurement of fully automatic gas plants Measurements with ultrasonic through the container wall are here particularly favourable, since no openings are needed. Since the ultrasonic transducers couple directly on the wall, the strongly smelling sulfides (Thioether) or Thiole (Merkaptane), used to the smell formation, cannot arrive into the environment. Problems with seal materials can be neglected thereby. No changes at the existing receivers are necessary. The dissolution of approx., reached with the devices the available. 1 mm is completely sufficient for the enterprise of the Odorier-plants (smell-plants). There these devices over appropriate interfaces (RS232 or RS485) order, are the integration problem-free possible into fully automatic stations. The remote supervision of the assigned level measuring technique permits remote monitorings. Also to the measuring point conveyed instructions the function on-line can be examined. Alarm functions can be examined by changing the measuring point parameters for effectiveness. Without putting out of operation of the components new measuring points can be installed, since no emptying of the containers is necessary. Weldings are not necessary for the installation of the measuring points.
