Sometimes things need to change - the best way would be to use our Continuous Level Probe but cost may be a deciding factor.
So - the unit to the right is available with one to seven stations with most connection options in all our materials.
On this model, a set screw tightens on the sliding tube and adjust to any height. Other models use compression fittings or strain relief options.
Choose from one of our multi level switch options - and ask for adjustable length.
