About this product
The sender your tank gauge actually needs: a 316 stainless reed-switch level sender, built to your exact tank depth and sealed to IP67. The float rides a sealed stainless stem with no wiper contacts — nothing to wear out or corrode, the right choice for fuel, fresh water, grey water and diesel tanks in the tropics.
Standard resolution (21 mm steps) suits most fuel and water gauges. Need finer steps for shallow tanks or precise monitoring? See the High Resolution (10 mm) version.
