The "Orifice Meter" is installed in the middle of the piping and easily measures the flow rate within the pipe by measuring the pressure (differential pressure) between two pressure measurement points. The installation is done via threaded piping, but the main body has a bolted flange design, allowing for the removal of the orifice plate. Switching between gas types can also be accommodated by exchanging the plates. When installed on the gas line of a burner, it allows for easy monitoring of combustion volume, making it convenient when there is no space for a gas meter or digital flow meter, or when measurements are needed in existing piping. 【Features】 ■ Inexpensive ■ Lightweight and very easy to install ■ Simple and robust structure ■ Useful for preventing vibration combustion in cases of low burner head pressure ■ By installing on both gas and air, air-fuel ratio management is possible, which is convenient during trial operation adjustments. ■ Contributes to energy savings through proper management of air-fuel ratios! ■ Since the plate diameter can be set to achieve any desired differential pressure, it can be used to adjust pressure loss in piping and as a high cut to prevent gas burner over-input. ■ For individual flow monitoring of multiple burners *For more details, please refer to the PDF document or feel free to contact us.
