The accuracy is an impressive ±0.1% R.S. with a maximum flow rate of 7500 L/min! A high-precision flow meter that is also used as a secondary standard!

The "OMG Series" screw meter volumetric flow meter has a structure that allows fluids to flow linearly, resulting in significantly lower pressure loss compared to conventional gear-type meters, and it also reduces the load inside the flow meter. The measurement accuracy is very high at ±0.1 RS, making it suitable for use as a flow reference instrument. It can measure a wide range of fluids, including high-viscosity liquids such as adhesives, sealants, PVC, and polyols, as well as low-viscosity fuels like gasoline, diesel, and kerosene. Additionally, with a variety of pickup sensors, it can accommodate a temperature range of up to -40 to 200°C. 【Do you have any of these concerns?】 - The data during high-temperature tests is poor, making accurate measurement difficult. - It breaks down quickly within 3 to 5 years due to high temperatures, necessitating replacement. - I want to measure high-viscosity fluids such as grease, adhesives, and sealants.
