Trudesign Aqualarm surface mount panel 12V

Designed and made in New Zealand, TruDesign Tank Monitors are a simple and reliable solution for detecting tank level. The Tank Monitor is designed to trigger when (for instance) a holding tank is nearly full, warning of tank overflow. Or by simply reversing the float on the sender, the tank monitor light will turn on when the tank level is below the float.
