To better serve you, we will need your tank, level gauge and product details and the purpose/function your level readings are used for. Once you have these, please contact us and we will be happy to help.
If your level device is not manufactured by Paul Mueller Company but is only an instrument on a Mueller Tank, you may want to contact the Level Gauge vendor for assistance and guide lines.
Regardless, we are willing to help regarding our tanks, even if we are not the specific vendor of its components.
