How do you calculate the output volume of a lift station with valve flap
Hello, how can I calculate the overflow volume discharged by a lift station whose pipes are fitted with valve flaps to prevent backflow in the event of a flood? What flowmeter do I install (height - speed)…? What brand? Thank you
