BLS 100 Orifice plate acc. DIN 19206 or ANSI Construction Orifice plate with welded-on handle/spade that can be installed directly between flanges with smooth sealing or tongue or RTJ faces. Available as a sharp edged, rounded or segmental orifice according to the conditions of use.It can delivered as single plate or as complete Flange Union with Flanges acc. DIN 19214 or Flanges acc. ANSI B 16.36 BLA 200 Ring Chamber Orifice Plate Construction Two-part Carrier-Ring with pressure-taps acc. DIN 19205 and exchangeable orifice plate.This can be supplied as an orifice (ISO 5167), a quarter circle nozzle or as a double coned orifice, according to the requirements. Carrier-ring and orifice plate are supplied with a flat seal. The seal ischosen to suit the medium and the working conditions, and the ring chamber orifice plate secured against damage during transport and installation Advantages As the orifice plate is easily exchangeable, alterations in the criteria of measurement are greatly simplified. The ring chamber tapping reduces faults caused by installation, and provides a good median between the plus and minus values.

构造

焊接在把手上的孔板可以直接安装在光滑密封法兰，榫槽法兰或RTJ表面
法兰之间。根据用途分为尖边孔板，圆形孔板或圆缺孔板。它可作为单件
孔板供应，也可和DIN19214法兰或ANSIB 16.36法兰一起提供

压差测量
压差测量一般通过法兰叶片或在管道里的量孔a1和a2的距离之间进行。
当使用调整系数计算节流孔时，要考虑上述的距离，所以要告知我们测
量点的位置。可供使用以下测压器：

　

　

　

　

　

　

　

法兰测压器(图1)
带光滑密封表面的法兰，PN 10-PN 100, 和DN 50-DN 500(根据DIN
19214第一部或ANSI B16.36)。

管道测压器(图2)

放压孔装在管道里。当密度少于200，a1和a2的距离与管道直径的比值超过
0,8时，要避免使用这种装置。在这种情况下调整系数变得不可靠，会出现
较大的测量偏差。

　

法兰弯角测压器(图3)

此装置几乎与ISO 15167的弯角排出孔相同。如果法兰叶片里有孔眼，
不能使用此装置。避免使用管线排出孔
