The LMA tank plugs from F.lli Giacomello are liquid level visual indicator plugs realized with a body in aluminum alloy D11S. The devices have an oil proof gasket, also available in aluminum or fibre on request. For adequate quantities, the company is also able to supply the tank plugs in anodized aluminum or brass OT 58 on request.
The sight window is manufactured in thermoplastic material ensuring optimum shock proofness, dimensional stability and not subject to aging. The transparency of the sight window does not change at high temperatures. The particular profile of the trim, in white prepainted aluminum, makes reading the liquid level very easy, also allowing rapid downflow if the quantity of the liquid decreases.
Maximum operating temperature is 80° C, and the pressure is 5 bar. On special request, the LMA can be supplied with internal O-ring in Viton and with sight window in pyrex, with maximum temperature of 200° C and pressure 10 bar.
