Turbine flowmeter (TUF of the following abbreviation) it is impeller type discharge (velocity of flow) plan main breed, impeller type flowmeter still has anemometer, water meter to wait.
In flowmeter of type of the TUF in all sorts of flowmeter, cubage and family family name mass flow plan it is product of first-rate of 3 kinds of repeatability, accuracy, and the characteristic that TUF has him again, like the structure component of simple, treatment little, weight light, maintenance convenient, throughput capacity is large (the flow that similar line of action can pass is large) and can get used to tall parameter (high temperature, high pressure and low temperature) etc. Up to now, product of this kind of flowmeter can amount to technical parameter: Caliber 4-750mm, pressure amounts to 250MPa, temperature is - 240-700 ℃ , other like such technical parameter two kinds of flowmeter are achieved hard.
TUF applies extensively at a few more the following measure an object: Oil, organic liquid, inorganic fluid, liquid gas, natural gas, gas wait with microtherm fluid. The have a change of luck that waits in oil of foreign liquefied petroleum gas, finished product and light qualitative crude and collect lose a station, large crude oil carries an end of cop to stand to use it to have trade close an account in great quantities. In Europe and American TUF it is the natural gas that is next to orifice plate flowmeter metric appearance, only Holand adopted all sorts of many 2600 measure on natural gas cop, pressure arrives from 0.8MPa the aeriform TUF of 6.5MPa, they already became admirable natural gas flowmeter.
Although the admirable and metric character of TUF gets the favour of people, but give the person's impression,be by mobile component, operating period is brief, unavoidable when choose hesitate, through the indefatigable effort of people, should say the circumstance has greatly change.
TUF serves as the most general flowmeter, its product already expanded the scope that produces for batch of much breed, whole set, much norms. Should point out, outside industrial department is being narrated to apply in great quantities before TUF is divided, also get applied extensively in a few special sections, be like science and technology of scientific research experiment, national defence, metric branch, the use of these domains kept away from fitly its weakness (unwell at be being used for a long time continuously) , develop its characteristic adequately (high accuracy, repeatability is good, can use at the condition such as high pressure, high temperature, low temperature and small discharge) . In these domains, it is according to be being measured the special requirement of the object undertakes special structure is designed mostly, they are special appearance does not undertake batch is produced.
