HLGZD德尔塔巴流量传感器是运用差压式的工作原理，插入式的安装方法设计而成的一种流量传感器。就工作原理，这是一种特殊的节流装置，其输出是差压。该传感器通过探头（或探针）取压，探头前后有两排不均匀分布的若干个引压孔。通过两排引压孔将管道从上到下（从左到右）的不同压力（流速）平均后形成了差压，进而可以计算出质量流量或体积流量。
Delta bar flow sensor is designed a kind of flow sensor which use differential pressure type work principle, plug-in installation method. Just working principle, it is a special kind of throttle device, its output is differential pressure. The sensor through the probe (or probe) take pressure, before and after the probe there are two row of uneven distribution of several lead pressure hole. Through the two rows lead pressure hole will formed a differential pressure through pipe from the top down (from left to right) of different pressure (flow) average, and can be calculated mass flow or volume flow.

德尔塔巴流量传感器是检测杆、取压口组成，它横穿管道内部与管轴垂直，在检测杆迎流面上设有多个总压检测孔，在检测杆背流面上设有多个静压检测孔，分别由总压导压管和静压导压管引出，根据总压与静压的差压值，计算流经管道流量。
Delta bar flow sensor is composed of detection bar, the pressure tapping points，it across the pipeline internal and pipe axis, in the detection bar meeting current surface is equipped with multi-holes for the total pressure detection, in the detection bar back flow surface is equipped with multi-holes for the static pressure detection, respectively by the total pressure connecting pipe and static connecting pipe eduction, according to differential pressure value caused between the total pressure and the static pressure, the pipe flow can be calculated.
