The "OMR type" is an orifice meter designed to measure flow with higher accuracy. To ensure high-performance accuracy, we not only welded pipes upstream and downstream of the orifice assembly but also finished the inner diameter of the flanges and pipes smaller than the required dimensions. Additionally, after welding, we performed boring and honing processes on the flanges and pipes as a single unit, ensuring that the finishing condition of the flange and pipe inner surfaces, as well as the dimensional tolerances, are within specified ranges. 【Features】 ■ Measures flow with higher accuracy ■ Finishing condition of the flange and pipe inner surfaces, as well as dimensional tolerances, are within specified ranges *For more details, please refer to the PDF document or feel free to contact us.

The "VT type" is a venturi that has extremely low pressure loss, allowing for measurement without accumulating mud or sediment in the constriction, and it also possesses durability. It can accommodate a wide range of applications, from small-diameter integrated machine-finished venturis to medium and large-diameter welded sheet metal venturis (wrapped venturis). The standard connection methods to piping are butt-welded steel pipe type and flange connection. 【Features】 ■ Extremely low pressure loss ■ Durable ■ Standard connection methods to piping are butt-welded steel pipe type and flange connection *For more details, please refer to the PDF materials or feel free to contact us.

The "FN/FNP type" is a flow nozzle suitable for measuring high temperature, high pressure, and large flow rates. It can measure fluids containing some solid particles without issues compared to an orifice. Additionally, under the same measurement conditions, it can allow more than 60% more fluid to flow than an orifice of the same diameter, and it also has excellent mechanical strength. In addition to standalone production, we also manufacture products that include short pipes for upstream and downstream. Please feel free to consult with us. 【Features】 ■ Suitable for high temperature, high pressure, and large flow rate measurements ■ Capable of producing standalone units as well as products that include short pipes for upstream and downstream ■ Many achievements in the production of low-reduction throat tap nozzles according to ASME PTC6/PTC19.5 *For more details, please refer to the PDF materials or feel free to contact us.

The "OB type" is an orifice block used for fluids that are high temperature, low temperature, high pressure, and prone to leakage. Similar to the "orifice ring," there are standard wafer types that are easy to install and replace, as well as welded connection types that are more resistant to leakage. The differential pressure extraction method can be either corner tap or flange tap. 【Orifice Types】 ■ Concentric sharp edge orifice ■ Quadrant orifice ■ Eccentric orifice ■ Notched orifice *For more details, please refer to the PDF document or feel free to contact us.

The "OF type / OFJ type" is an orifice flange that combines an orifice plate with a differential pressure take-off port, along with bolts, nuts, and gaskets. Flange standards include JIS standards, ASME standards, and JPI standards, and the connection methods to piping are butt welding and socket welding. Additionally, depending on the shape of the gasket seat, there are flat face, raised face, and ring joint options. [Seat Shapes] ■ OF type: RF - Flat Seat ■ OFJ type: RTJ - Ring Joint Seat *For more details, please refer to the PDF document or feel free to contact us.

The "OR type" is an orifice ring used for measuring the flow rate of fluids with relatively low operating pressure. It is inserted between pipe flanges, making installation and replacement easy. It is a ring with a differential pressure take-off, and when combined with an orifice plate and gasket, it forms an orifice ring assembly. The differential pressure take-off method is a corner tap. 【Features】 ■ Used for measuring the flow rate of fluids with relatively low operating pressure ■ The differential pressure take-off method is a corner tap *For more details, please refer to the PDF document or feel free to contact us.

The "Orifice Plate OP Type" has a simple shape, making installation and replacement easy. It is also inexpensive and has high reliability despite its low cost, which is why it is widely used as a flow element. There are various types, including concentric orifices, eccentric orifices, elliptical orifices, quarter-circle orifices, and rectangular orifices.
