This eliminates cost of installation of Differential Pressure Transmitter with impulse piping up to the orifice assembly. The transmitter is mounted on the orifice assembly through a 3-Valve H-type manifold. Available with line sizes of 2" & below. However due to process temperature limits of the transmitter , this assembly cannot be used for process temperatures above 120 Degrees Centigrade.
