So if connected in series, a very small current will flow or no current will flow. An ideal voltmeter draws $0$ current from the circuit. So when we arrange it in series, It doesn't work as a voltmeter but as resistance and also the reading is shown by the voltmeter is the voltage across its terminals.
The voltmeter reading will be $12 V$.
