Abstract

Изобретение относитс  к измерительной технике. Цель изобретени  состоит в повышении точности измерени  расхода за счет выполнени  трубопровода в форме трубы Вентури и обтекаемого тела в виде цилиндра с конусными насадками на концах. Поток контролируемой среды, поступающий на вход расходомера, испытывает сжатие со стороны конфузора 1, переход щего в цилиндр 2, и конусного насадка 4 с цилиндром 5. В результате сжати  между входным и суженным сечени ми образуетс  перепад давлени , воспринимаемый измерительным прибором. Диффузор 3 и конусна  насадка 6, смонтированные на выходе расходомера, позвол ют потоку плавно и симметрично расшир тьс , что уменьшает потери энергии. 2 ил.

  1. Формула изобретения
    Расходомер, содержащий обтекаемое тело, помещенное в трубопровод соосно с ним, отличающийся тем, что, с целью повышения точности измерения расхода, обтекаемое тело выполнено в виде цилиндра с коническими насадками на концах, трубопровод имеет ввд трубы Вентури, длина цилиндрической части которой равна длине цилиндрической части обтекаемого тела, а конусные начадки расположены в конфузорной и диффузорной частях трубы Вентури, при этом углы насадков равны соответствующим углам конусности конфузора и диффузора трубы Вентури.
