HLGZD德爾塔巴流量傳感器是運(yùn)用差壓式的工作原理，插入式的安裝方法設(shè)計(jì)而成的一種流量傳感器。就工作原理，這是一種特殊的節(jié)流裝置，其輸出是差壓。該傳感器通過探頭（或探針）取壓，探頭前后有兩排不均勻分布的若干個引壓孔。通過兩排引壓孔將管道從上到下（從左到右）的不同壓力（流速）平均后形成了差壓，進(jìn)而可以計(jì)算出質(zhì)量流量或體積流量。
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.

德爾塔巴流量傳感器是檢測桿、取壓口組成，它橫穿管道內(nèi)部與管軸垂直，在檢測桿迎流面上設(shè)有多個總壓檢測孔，在檢測桿背流面上設(shè)有多個靜壓檢測孔，分別由總壓導(dǎo)壓管和靜壓導(dǎo)壓管引出，根據(jù)總壓與靜壓的差壓值，計(jì)算流經(jīng)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.
