What is the diameter of straight piping of IN side?
Be sure to allow straight pipe length that is minimum 8 times the port size upstream and downstream of the switch piping to measure flow rate accurately.
When anything is installed such as throttle valve, it should be placed on the secondary side. When throttle valve is installed on the primary side, be sure to allow sufficient length of straight pipe.
