Oval

These flowmeters used to measure minute flow rate are precisely adjusted in the factory, so it is necessary to take special care when unpacking, installing in the piping and testing. Never let foreign materials enter into the measuring chamber. Flush the piping well enough before installation. It is essential that you always avoid violently spinning the rotor by flushing air or an excessive flow rate in a short period of time. Only use Oval's strainer dedicatedly designed for these flowmeter.
