We can’t measure the flow value directly.

First create diff pressure in flow line using orifice,
annular pipe, venturi meter etc…

Then measure the diff pressure using any diff pressure
transmitter take square root get flow value.

Flow value = Sq.Root (Diff Pressure)

There are two chlorination tonners both are connected to two pressure swithes and the pressure switch is connected to SOV which operates the valve to changeover the tonner selection i.e if pressure one tonner goes low the other tonner should come in line if it is inautomatic selection design a circuit using relays ?
