The molecule consists of one chlorine atom and two oxygen atoms represented in the chemical formula ClO2. /Vyl2q. Chlorine dioxide measurement Chlorine dioxide (ClO2) is an instable, non-storable, toxic gas with a characteristic scent. Something to keep in mind, is that due to the nutating discs nature, the accuracy of this type of flow meter can be adversely affected by fluctuations in liquid viscosity. 2 g/l ClO2 that can be safely handled and stored for several days. 0000001570 00000 n

A multiphase flow meter is a device used to measure the individual phase flow rates of constituent phases in a given flow (for example in oil and gas industry) where oil, water and gas mixtures are initially co-mingled together during the oil production processes. /DecodeParms [null <>] There are inherently more leak, A combination of Venturi tube and orifice plate, it features the same tapering intake portion of a venturi tube but has a shoulder similar to the orifice plates exit part to create a sharp pressure drop.

flow transmitter yokogawa multivariable mass rate orifice measurement example figure valve control actuators principle xref )%\%? Conceptually, a magnetic resonance multiphase flow meter consists of three sequential steps: 1.Creating a net magnetization by aligning the magnetic moments of hydrogen atoms in an applied, constant magnetic field. The position of the disc divides the chamber into compartments containing an exact volume.

Multiphase streams are typical of the O&G fields, since the producing wells normally generate mixture of liquid and gaseous hydrocarbons with a variable quantity of water. 32 0 obj<> endobj pb%PYi&xn|giUAAL//G2V\sx7! mms manifold dl3 msp albacora HVn0_jI(vsl:/yxL$%$bq3"YF /qEI~1H*h#G]eO7tgMTH-"J{[[6o,8h Since oil, gas and water all contain hydrogen atoms, multiphase flow can be measured using magnetic resonance. 0000000716 00000 n Knowing single rates of gas liquid and water is crucial for the production industry in order to monitor the reservoir, to improve the well performances and to optimize the production. 0000000776 00000 n 0000002609 00000 n This motion is translated into rotary motion by means of a ball and shaft, which is attached to the disc. Since these meters have significantly lower permanent pressure losses than orifice meters, Dall tubes are widely used for measuring the flow rate of large pipe works.
