Actually I'm using awesomebox package to draw blocks around text. Here there is an example.

documentclass[a4paper,12pt]{article}

usepackage{awesomebox}

usepackage{fontawesome5}

usepackage{lipsum}



begin{document}

awesomebox[violet]{2pt}{faRocket}{violet}{lipsum[4]}

end{document}

Into the guide there is written that "The specific aim of this package is to use FontAwesome 5 icons to ease the illustration of these boxes."

Is there a font, a symbol to be inserted (instead of the fontawesome5 symbols) with a suitable strategy, to have three different types of speedometer without text like this image?

A simple pic with the "speed" as parameter may do.

documentclass[tikz,border=7pt]{standalone}

usetikzlibrary{decorations.text}

begin{document}

begin{tikzpicture}[pics/speedometer/.style={code={

 foreach X/Y [count=Z] in {green!70!black/low,orange/medium,red/high}

  {fill[fill=X] (240-Z*60:4) arc(240-Z*60:180-Z*60:4) -- 

    (180-Z*60:3) arc(180-Z*60:240-Z*60:3) -- cycle;

   path [decorate, decoration={text along path,

   text={|color{white}Hugesffamilybfseries|Y}, text align=center}] 

    (240-Z*60:3.2) arc(240-Z*60:180-Z*60:3.25);}

   fill (180-#1+8:0.3) arc (180-#1+8:180-#1+344:0.3) -- (180-#1-0.5:3.25)

   -- (180-#1+0.5:3.25) --  cycle;

  }}]

  path (0,0) pic{speedometer=45}

  (0,-5) pic{speedometer=80}

  (0,-10) pic{speedometer=160};

end{tikzpicture}

end{document}

An arguably more fancy version thereof is obtained when making the color transitions smooth. To this end we need to rotate and flip the color wheel that comes with the shadings library. This can be done using transform canvas, which has some side-effect, which is why the results get stored in a savebox and then reused.

documentclass[tikz,border=7pt]{standalone}

usetikzlibrary{decorations.text,shadings}

newsaveboxColorWheelRotated

sboxColorWheelRotated{begin{tikzpicture}

clip (180:4) arc(180:0:4) -- (3,0) arc(0:180:3);

    shade[shading=color wheel,transform canvas={

    rotate=-65,xscale=-1}] (0,0) circle [radius=4];

end{tikzpicture}}

begin{document}

begin{tikzpicture}[pics/speedometer/.style={code={

 path (0,0) node[above,inner sep=0pt] {useboxColorWheelRotated};

 foreach X/Y [count=Z] in {green!70!black/low,orange/medium,red/high}

  {

   path [decorate, decoration={text along path,

   text={|color{white}Hugesffamilybfseries|Y}, text align=center}] 

    (240-Z*60:3.2) arc(240-Z*60:180-Z*60:3.25);}

   fill (180-#1+8:0.3) arc (180-#1+8:180-#1+344:0.3) -- (180-#1-0.5:3.25)

   -- (180-#1+0.5:3.25) --  cycle;

  }}]

  path (0,0) pic{speedometer=45}

  (0,-5) pic{speedometer=80}

  (0,-10) pic{speedometer=160};

end{tikzpicture}

end{document}

In order to make this symbols you may want to kick out the texts.

documentclass[a4paper,12pt]{article}

usepackage{awesomebox}

usepackage{lipsum}

usepackage{tikz}

tikzset{pics/speedometer/.style={code={

 foreach X/Y [count=Z] in {green!70!black/low,orange/medium,red/high}

  {fill[fill=X] (240-Z*60:4) arc(240-Z*60:180-Z*60:4) -- 

    (180-Z*60:3) arc(180-Z*60:240-Z*60:3) -- cycle;}

   fill (180-#1+8:0.3) arc (180-#1+8:180-#1+344:0.3) -- (180-#1-0.5:3.25)

   -- (180-#1+0.5:3.25) --  cycle;

  }}}
