Generally Voltmeter shows the Potential Difference between two points in a circuit ; That is the reason why it is connected parallel to the circuit connecting two points
If It is connected in series it cannot measure the Potential difference .
So , It is connected parallel to the circuit
If It is connected in series it cannot measure the Potential difference .
So , It is connected parallel to the circuit

Ammeter:-
An ammeter is just a converted Galvanometer and measures the current flowing through the circuit by showing proportional deflection. An ammeter is formed by connecting a Galvanometer with a low resistance in parallel.
So the Ammeter is connected in series with the circuit elements and measures the current flow in a circuit.
Voltmeter:-
A Voltmeter is also a converted Galvanometer which measures the amount of Voltage (or) in other words the potential difference accross two points in a circuit. A voltmeter is formed by connecting a Galvanometer in series with a high resistance.
So the Voltmeter is attached in parallel in a circuit and measures the voltage in a circuit.
And if this is not maintained then there is a high chance for the ammeter to get damaged due to low resistance
