No need for pressure measurement, easy to operate! It is possible to determine the flow rate value by measuring only the pressure on the upstream side.
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.
