楔形流量计是一种差压式流量仪表，利用其内部安装的特殊节流件，迫使管道中的流体的流动发生变化，在节流件的前后产生压力差，从而达到测量流量的目的。

　　楔式流量计工作原理Working principle

　　流体通过模形流量计时，由于模块的节流作用，在其上、下游侧产生了一个与流量值成平方关系的差压，将此差压从楔块两侧取压口引出，送至差压变送器转变为电信号输出，再经专用智能流量计算仪运算后，即可获知流量值。

　　When the fluid passes through the wedge-shape flowmeter，a differential pressure in square relationship to the value of the flow on the upstream and downstream sides due to the throttling effect of the wedge occurs.Divert the differential pressure from the pressure-tapping holes on both sides of the wedge and send it to the differential pressure transmitter to be converted into electric signals before output，which are then calculated by a special intellignet flow calculator，ａnd the value of the flow can be acquired.
