(iii) Auxiliary equipment
(1) Oil sealing and air purging
If it is not possible to guide the measured fluid directly to this device due to suspension,
high viscosity, high temperature, corrosiveness, etc., use sealing or purging. For information
regarding sealing and purging methods, please consult with the relevant personnel
at our company.
(2) Throttle valves for pulsation flow prevention
If there is high-speed pulsation flow in the process fluid, or high levels of pressure fluctuation,
fluctuations can be suppressed by installing a throttle or the like in the connecting pipe.
