Researches of Plunger Flowmeter with the Line Decoder as a Component of an Odorizer

Abstract

In the article there are results of researches of plunger liquid flowmeter with the aim of creation of device of volume measurement and volume flow rate of odor substance with high metrology characteristics and possibility of construction of effective odorizers on their base. For the strict registration of volume and volume flow rate of liquid it is proposed to determine moving of piston of plunger meter by means of line decoder and to apply this principle of fixing of the linear moving for determination of level of float sensor. This proposed solution is realized in odorizer of FLOUTEC-TM-D. This scientific study is directed on the decision of vital task of providing of safe conditions of the use of such important power resource as natural gas in the systems of preparation, transporting, distribution and consumption by its odorization, i.e injection of the substance with a strong specific smell. Important thing is providing of precision and reliability of odorization because while «overdose» by an odorant of natural gas there is a danger to the health of individual in consequence of poisoning by the hydrogen sulfide even in case of absence of gas leakage. During «underdose» effluxes of gas do not appear, the dangerous concentration of gas mixture appears with air that results in explosions in domestic and other apartments, In view of this it is necessary to provide reliable and effective identification of effluxes of natural gas that secure an auxiliaries and consumers from accidents and harm to their health and negative operating on an environment.
