Onward Manufacturing 00030 Propane Tank Gas Level Indicator

Product Description

The ONWARD MANUFACTURING 00030 is a magnetic liquid crystal gas level indicator designed to show remaining propane fuel in LP tanks. The device attaches to the exterior of the tank and uses liquid crystal technology to detect fuel level through the tank wall. It gives a visual readout when propane levels are running low, allowing technicians and service pros to identify tanks that need replacement or refill before a job is interrupted. Weighing just 0.066 pounds, the unit is compact and easy to carry on a service truck or store with standard gas equipment.

This indicator is compatible with Type 1 propane tanks, which feature external threading on the tank collar. It is suited for residential and light commercial applications where standard LP cylinders are in use, such as outdoor cooking equipment, space heaters, and portable propane appliances. The unit works across all fuel levels, not just at full or empty, giving a usable readout throughout the tank life cycle. The indicator must be pressed on firmly and seated tightly against the tank surface to produce an accurate reading.
