[Tex/LaTex] Remove arrow from ammeter in circuitikz

Question

I'd like to remove the arrow from the ammeter symbol in circuitikz so that the symbol matches the one below. Is this possible?

Answer 1

Since Version 0.9.0 (2019-05-10), the generic meter type rmeter (round meter) has been added which allows you to set the internal symbol with the t=... option.

You might then use that to create a circuit consisting of a battery, one resistor, an ammeter, and a voltmeter to measure the current and voltage of that circuit like this:

\documentclass{article}
\usepackage{circuitikz}
\begin{document}
\begin{circuitikz}
\draw (0,2)   to[battery]       (0,0)
      (0,2)   --                (2,2)
      (2,2)   to[R=\(R_1\)]     (2,0)
      (2,2)   --                (4,2)
      (4,2)   to[rmeter, t=V]   (4,0)
      (4,0)   --                (2,0)
      (2,0)   to[rmeter, t=A]   (0,0);
\end{circuitikz}
\end{document}

Which should produce the following output:
