The "Sonic Nozzle" is a revolutionary flow meter with a Venturi shape that utilizes the properties of gas flow in the sonic range (critical flow). Its regularity has already been proven. Regarding the verification of flow rate values, we are constantly establishing reliability through cross-checks using ultra-precision machined nozzles and cross-checks with the calibration equipment of the National Institute of Advanced Industrial Science and Technology. 【Features】 ■ Easy to install and compact, making it simple to integrate into other devices ■ No wear parts or mechanical moving parts, resulting in excellent durability and reproducibility ■ Made of stainless steel, so there is almost no change over time ■ High accuracy and reliability allow it to be used as a constant flow generation device or flow reference gauge, and it can also calibrate other flow meters *For more details, please refer to the PDF document or feel free to contact us.

The "Assy." is a small gasoline high-pressure pump in which oil filled inside the piston acts on a diaphragm to deliver liquid at high pressure. All wetted parts are made of gasoline-resistant components. Additionally, there are no sliding parts, so there is no generation of wear particles. 【Features】 ■ Discharge pressure is typically 30MPa, with a maximum of 40MPa ■ All wetted parts are made of gasoline-resistant components ■ No generation of wear particles ■ Low pulsation ■ Excellent durability *For more details, please refer to the PDF materials or feel free to contact us.

The "laminar flow meter" is a high-precision differential pressure flow meter that utilizes the phenomenon known as the "Hagen-Poiseuille law," which states that when a fluid flows in a laminar manner through a cylindrical pipe or between two flat planes, the pressure drop over a certain distance is proportional to the volumetric flow rate. It has a wide measurement range and a linear relationship between differential pressure and flow rate. Additionally, it is highly accurate due to calibration with a master sonic nozzle. 【Features】 - Low pressure loss (MAX 2.6 kPa) - Excellent linearity and reproducibility - Good responsiveness (MAX 30 Hz) - Suitable for measuring small flow rates - Easy maintenance *For more details, please refer to the PDF document or feel free to contact us.
