A flow-rate measurement assembly for measuring a flow rate of a medium through a measurement pipe, comprising at least one differential-pressure producer, and comprising a differential-pressure measurement transducer for providing a differential-pressure measurement signal, which depends upon the ...
Piezoresistive Differential Pressure Measurement: The working principle of a piezoresistive differential pressure transmitter is based on the piezoresistive effect, a phenomenon where the electrical resistance of a material changes when subjected to stress. The main structure of the sensing element includes ...
When the fluid flow getting bigger, the pressure difference getting bigger at the same time, so the flow rate can be measured based on the pressure difference. This measurement method is based on the Continuity equation(Law of conservation of mass) and the Bernoulli's principle(Conservation of...
The principle of capacitive pressure measurement is based on the measurement of the capacitance, which is dependent upon the plate separation. The physical principle of capacitive pressure measurement consists of using a main body with a metallic diaphragm, which forms one of the two plates of a d...
The Deltabar PMD75 differential pressure transmitter with piezoresistive sensor and welded metallic membrane is used in all industries for continuous measurement in liquids, vapors and gases. The 3-key operation enables simple and reliable commissioning
Measuring one-phase fluid flows on the basis of differential pressure methods is the most often used principle for measurement of flows in industry. In the... I Bajsic,I Dolenc 被引量: 0发表: 1994年 UPPER CRUST REGIME OF STRESSES ACCORDING TO THE BOREHOLE MEASUREMENTS COMING FROM THE TRANS...
pressure sensors are made with intermediate transducers (pressure stress → displacement) and terminal transducers (stress → measurement of electrical parameter). The intermediate types include liquid manometric transducers, springs, membranes, and bellows; among the terminal types are rheostatic, inductive...
(2)Differential vapor pressure measurement The differential method can be compared under some aspects with the absolute method, but there are some advantages. The measuring principle is to obtain the vapor pressure difference between the pure solvent and the polymer solution at the measuring temperature...
When measuring air flow using the differential pressure principle, a probe with an average Pitot tube structure can be used. The average Pitot tube has multiple measurement holes on both the total pressure and static pressure sides, allowing for an average of the air flow inside the tube. For...
