Differential pressure (DP) flowmeters are flowmeters with a restriction mechanism, such as an orifice (plate), in the flow path and measure the flow rate by detecting the pressure difference (differential pressure) that occurs before and after the restriction element due to the flow.

ORIFLOMETER
DP flowmeters that measure the liquid or gas flow rates in main pipes by providing branch pipes with orifices and equipped small-diameter variable area flowmeters or differential pressure gauges to the branch pipes.
Easy to install and economical to measure flow rates even in medium to large diameters due to its bypass design.
Wide range of products, from local indication type without power supply to various alarms, flow signal outputs and explosion-proof certified products.

V-cone® Flowmeters/Wafer Cone® Flowmeters
A V-shaped cone is used as the restriction mechanism, and it fundamentally eliminates the need for straight pipe length, achieving lower pressure loss compared to an orifice.
Suitable for liquids, gases and steam applications.
