  3. 1. Application purposes of modern level gage Why is the level gage bought: • increasing ofmeasuring accuracy; • elimination of possibilities of individual errors at measuring; • automation of measuring process – refusal fromgauge stick; • use of measured data inautomated accounting systems; • obtaining of information aboutproduct density; • use as signalling device in system of EDES; • use as a device for automatic calibration of tanks; • continuous observation of life cycle of tank and product in it • during the whole storage period

  4. 2. Review ofUkrainian market of level gages • According to the used measuring method: • magnetostriction • (“float”) ~ 64% • capacity ~ 0,3% • - radio frequency ~ 12% • ultrasonic • (only “ND”) ~ 17% • - others~ 6,7% * All known types of objects are taken into account (filling stations, petroleum storage depots, industry, railway, etc.)

  5. 2. Review ofUkrainian market of level gages • The main brands, used in Ukraine: • - Veeder-Root (TLS…) • OPW (Site Sentinel…) • Struna (PSD…) • “ND” (UUS, UUP…) ~ 24% • - othermanufacturers ~ 18% ~ 58% * All known types of objects are taken into account (filling stations, petroleum storage depots, industry, railway)

  6. Characteristic features of ultrasonic level measuring method Background of creation and developmentof method: • conversion of method frommilitary production ofUSSR; • deeplong-term theoretical and practicalinvestigation of • ultrasound extension properties in liquid medium; • application practice on hundreds of objects of varioussections and • areas of practice (filling stations, petroleum storage depots, • utility companies, industry, etc.)

  7. Characteristic features of ultrasonic level measuring method Positive side of the use of ultrasound as“measuring device”: • possibility of use of noncontact measuring method throughmetal walls of tanks; • possibility of determination of weight characteristic of fuel of standardized types*, • percentage ratio of propane/butane for liquefied gas; • absence of high requirements to wear resistance and strength of equipment design • at realization of method ; • - simplicity of transducer design and method for their installationin/on tanks, • as a result– simplicity of service maintenance andsimplified service support procedure, • absence of necessity of expensive SPTA; • - durability of ultrasonic sensors is not less than14 years *There is a possibility of identification of oil product manufacturer

  8. Characteristic features of ultrasonic level measuring method Principle of operation of ultrasonic method: • based ondetection and ranging of reflecting surface by means of ultrasound • throughsound transparent media; • - level gage carriers out time measuring between radiation of acoustic signals and • arrival of echo signals fromreflecting surfaces; • according to the results of detection and ranging a boundary line of material • (liquid level) or two unmixed liquids of various density (level of bottom water) • is determined, • in case ofstratification– levels for separation of liquids; • self-diagnostic check– presence of “measuring base”, automatic regulation of signal • amplification level, etc.

  9. Characteristic features of ultrasonic level measuring method Unquestionableadvantages of ultrasoniclevel gages, to which it is necessary to pay attention: • - calibration interval of 2 years (rivals– 1 year); • periodic verification can take place directly on object - • special imitator is developed for this purpose and verificationcan be carried out without • dismantling of probes (rivals– dismantlingandexport); • central block of level gage isunified: more than 64 probes of different types • (immersion, surface contact, air, OPW probes) can be simultaneously connected to one • central block; • - absence ofmoving elements, exception of mechanical wear

  10. 4. Review of models of ultrasonic level gages Level gages with SURFACE CONTACT electroacoustic transducers: • - used for noncontact measuringof liquid leveland estimate of density; • are essential for control of tanks with liquefied gas ortoxic aggressive liquids; • allow carrying out measuring without opening of tanks onrailway vehicles; • - while working with gas– determination of propane/butane ratio Stationarylevel gageUUS-00* withsurface contact transducers Portable level gageUUP for railway tanks** * There are no any analogs in Ukraine ** estimation measuring of product density without opening of tank is possible

  12. 4. Review of models of ultrasonic level gages Level gages withIMMERSION electroacoustic transducers • for operative liquid level instationary SHTandSVT; • calculation ofweighted volumetrically density *; • measuring of separation of level of two material • (bottom water); • calculation of liquid mass and volume; • signaling of limiting and given levels of liquids; • determination oftemperature cut throughout the height • of probe; • number of serviced probes– more than64 * base delivery set comprises a functional for estimation of density
