Description

Изобретение относитс  к измерени м расхода жицкости с помощью турбинных датчиков расхода. Известно устройство дл  непрерывного измерени  расхода жидкости, содержащее последовательно включенные в об.щую магистраль датчики большого и малого расходов , обводную магистраль последнего с электроклапаном, электронный коммутатор и блок управлени , вход которого св зан с выходом датчика большого расхода, а выходы - со входами управл ющей обмотки электроклапана и электронного коммутатора 1. Однако датчики расхода известного уст ройства не имеют линейного суммарного коэффициента передачи в диапазоне расхода , перекрываемом обоими датчиками. Целью изобретени   вл етс  расширение диапазона работы путем получени  линейного суммарного кoэqJфициeнтa передачи в диапазоне расходов, перекрываемом обоими датчиками. Это достигаетс  тем, что предлагаемое устройство дополнительно содержит  вухканальный блок масштабного преобразоваHiiH , вхоцы которого св заны соответственно с выходами электронного коммутатора и блока управлени  и один из каналов которого имеет коэффициент передачи, равный отношению коэффициента передачи датчика большого расхода, а другой - равен единице , На чертеже представлена структурна  схема предлагаемого устройства. Устройство содержит датчики 1 и 2 большого и малого расходов, обвоаную магистраль 3 с электроклапаном 4, электронный коммутатор 5, блок 6 управлени  .и блок 7 масштабного преобразовани . Устройство работает следующим образом . В исхоцном состо нии электроклапан 4 находитс  в положении, при котором обводна  магистраль 3 датчика 2 малого расхода перекрыта.This invention relates to measuring the flow of lash with turbine flow sensors. A device for continuous measurement of fluid flow is known, comprising high and low flow sensors in series with a common line, a bypass line of the latter with an electro-valve, an electronic switch and a control unit, the input of which is connected to the output of the high flow sensor and the outputs of the solenoid valve and the electronic switch 1. However, the flow sensors of the known device do not have a linear total transfer coefficient in the flow range covered by both by sensors. The aim of the invention is to extend the range of operation by obtaining a linear total transmission coefficient in the range of costs, overlapped by both sensors. This is achieved by the fact that the proposed device additionally contains a two-channel large-scale conversion unit HiiH, the inputs of which are associated respectively with the outputs of the electronic switch and control unit and one channel of which has a transmission coefficient equal to the ratio of the transmission coefficient of the high flow sensor The drawing shows a block diagram of the proposed device. The device contains sensors 1 and 2 of high and low flow rates, a wired line 3 with an electro-valve 4, an electronic switch 5, a control unit 6 and a scale conversion unit 7. The device works as follows. In its original state, the solenoid 4 is in a position in which the bypass line 3 of the small flow sensor 2 is closed.
