OPTIBAR OP 4100

The OPTIBAR OP 4100 is an orifice plate with an integrated annular chamber and corner taps. It features a carrier ring that is split into two pieces to form the two ring chambers. Within the ring chambers an average of flow disturbances can be achieved and therefore a more stable pressure signal can be measured.The orifice plate with annular chamber is intended for installation between standard flanges.

Product highlights

  • Cost-effective DP flow element according to EN ISO 5167
