Circuitikz uses \textbf inside, which is a LaTeX macro. Unfortunately, this is
hardcoded within the ammeter and voltmeter nodes, so you can't easily change
it. Instead you can simply provide a macro that does the correct thing.
\usemodule[circuitikz]
\let\textbf\bold % <---
\starttext
\starttikzpicture
\draw (0,0)to[ammeter, t=A, i=$i$] ++(3,0);
\draw (0,4) to[rmeter, t=V, v>=$v$] ++(3,0) ;
\draw (0,2) to[voltmeter, l=$U$] (++3,2);
\stoptikzpicture
\stoptext
