Design and applications
The DDM-DS11 metering orifice measures and monitors the flow rate of liquids.
The device works according to the principle of differential pressure.
At the orifice, a differential pressure drop occurs, which is square proportional to the volume flow rate passing the conduit.
The user mounts the orifice between flanges or with Rp pipe unions into the conduit. The unimpeded, straight tube length has to be 6 DN before and 4 DN behind the mounting position.
The DS11 gauge contains a rugged and uncomplicated diaphragm system. The differential pressure generates a unilateral force at the membrane which moves the diaphragm system against the measuring range springs. A centre-mounted tappet transfers motion of the diaphragm system to indicator movement and to initiating elements of the microswitches. Due to the completely mechanical functionality, no external power supply is needed. The applications of DDM-DS11 are engineering and process technology such as the monitoring of coolant streams in plants.
The display pressure gauge can be equipped with one or with two microswitches.

根據(jù)DIN EN 1092-1在法蘭之間進(jìn)行安裝，根據(jù)DIN EN ISO 228進(jìn)行內(nèi)外螺紋連接，或者根據(jù)ISO 7-1進(jìn)行管道連接
一臺(tái)用于所有安裝情況和流向的設(shè)備
適用于液體和氣體
無(wú)活動(dòng)部件，無(wú)磨損
校準(zhǔn)標(biāo)準(zhǔn)測(cè)量范圍或根據(jù)客戶要求
測(cè)光范圍1：6

設(shè)計(jì)與應(yīng)用
DDM-DS11計(jì)量孔板可測(cè)量和監(jiān)控液體的流量。
該設(shè)備根據(jù)壓差原理工作。
在孔口處會(huì)出現(xiàn)壓降，該壓降與通過(guò)導(dǎo)管的體積流量成正比。
用戶可以將孔口安裝在法蘭之間或通過(guò)Rp管接頭安裝到導(dǎo)管中。暢通無(wú)阻的直管長(zhǎng)度必須在安裝位置之前6 DN，在安裝位置后面4 DN。
DS11壓力表包含堅(jiān)固耐用的隔膜系統(tǒng)。壓差在膜片上產(chǎn)生單向力，使膜片系統(tǒng)靠著測(cè)量范圍彈簧移動(dòng)。中心安裝的挺桿將隔膜系統(tǒng)的運(yùn)動(dòng)傳遞至指示器的運(yùn)動(dòng)以及微動(dòng)開(kāi)關(guān)的啟動(dòng)元件。由于完全具有機(jī)械功能，因此無(wú)需外部電源。 DDM-DS11的應(yīng)用是工程和工藝技術(shù)，例如監(jiān)測(cè)工廠中的冷卻劑流。
顯示壓力表可以配備一個(gè)或兩個(gè)微型開(kāi)關(guān)。
