TruDesign Short Tank Monitor Sender

Monitor your tank levels effortlessly with the TruDesign Short Tank Monitor Sender, a reliable float switch manufactured in New Zealand from durable, composite materials. Designed for 12 V or 24 V systems, this sender lights up to warn when your holding or freshwater tank is nearly full—or, by flipping the float, alerts you when it’s nearly empty—helping avoid overflows and dry runs 

Compact in size (approx. 103 mm long, 76 ± 2 mm trigger depth), it fits into a 28 mm hull fitting or flange and seals tightly with a gasket or BSP thread to ensure leak-free operation . Purpose-built to resist chemicals, it’s ideal for marine sanitation environments and works seamlessly with TruDesign Tank Monitor Display Panels. Low-power draw ensures it won't drain batteries during extended cruises
