Inline propane tank level indicator gauge for Type 1/QCC1 or POL propane connections, with an easy-to-read glow-in-the-dark dial and multi-color level display.
The Flame King YSN212B is an inline propane tank level indicator gauge designed to help show when a propane cylinder is running low. It installs between the propane tank and fuel line with no tools required on compatible Type 1/QCC1 or POL propane connections.
The glow-in-the-dark dial and multi-color level indicator make it easier to check propane level at a glance when grilling, camping, heating, or running compatible outdoor propane equipment. This gauge is a level indicator, not a digital flow meter or total usage monitor.

Easy-to-read dial helps with low-light propane checks
Works with compatible Type 1/QCC1 or POL propane connections
Attaches between the tank and fuel line on compatible setups
Flame King YSN212B indicates approximate propane level based on pressure/conditions. It does not measure exact gallons, pounds, runtime, flow rate, or total propane usage. For exact fill level, propane should be checked by weight or by a qualified propane supplier.
Turn off the propane cylinder before installation. Attach the gauge between the propane tank valve and the appliance fuel line, regulator, or adapter on compatible Type 1/QCC1 or POL connections. Tighten by hand where applicable, then slowly open the tank valve and leak-test all connections with approved leak detection solution before use.
Package Contents: • 1 Flame King YSN212B propane tank level indicator gauge NOT Included — May Also Need: • Propane cylinder • Propane regulator • Propane hose or pigtail • Appliance-specific adapter • Leak detection solution • Digital flow meter or total usage monitor This listing is for the propane level gauge only unless otherwise stated.
Confirm the propane tank and appliance line use a compatible Type 1/QCC1 or POL connection and that there is enough clearance to install the gauge without putting strain on the hose or regulator. Gauge readings are approximate and can vary with temperature, cylinder size, and propane pressure.
Propane is flammable. Turn off the tank before installing or removing the gauge, use only compatible propane fittings, and leak-test all connections before use. If propane odor is detected, shut off propane if safe, ventilate the area, avoid flames/sparks/electrical switches, and have the system inspected before use.
