The Grill Gauge vs. The Competition

Grill Gauge Features & Benefits

Features  Benefits 
E-Z ‘auto-check’ indicator Hook Grill Gauge to tank, lift slightly, return tank to ground and black arrow automatically sets at propane level
Re-enforced handle Ease and comfort
Used and recommended by propane professionals Product integrity and reliability
Propane levels are “weight-calibrated” Consistent w/propane industry which measures & fills by weight
Hand-held Portable; can take to store and verify propane contents of next tank
Instant read-out Works immediately – on-demand; no “pre-conditions” for operation
Simple to use Hook, lift, and look
Used when tank valve is open or closed  Versatile/flexible
Colored indicator face gauge Works like gas gauge in car – w/dark red indicating tank is near empty
Versatile Can be used even w/tank connected to hose

The Competition

Low End (stick-on tapes “cheap”)

High End (pressure gauges or pressure valves “costly”)

Stick on / or magnetic tape
– Flimsy
– Methodology not used or recommended by propane industry
– Generally unreliable
– Temperature sensitive; doesn’t work without hot water
– Wears out; limited shelf life
– Requires time to work
– Tedious to use
– Impractical

Pressure Valves
– Methodology not used or recommended by propane industry
– Temperature and volume sensitive
– Requires constant connection between tank and hose
– Gas valve must be open at all times to work
– Poor performance and reliability resulting in false readings (aka FALSE POSITIVES)
– Not portable – can’t take to LP exchange dealer to check next tank purchase

The Small Trailer Enthusiast Reviews The Grill Gauge

Periodically I may let you know about some camping & RV gadgets that I’ve come across that I use & like. First up on the list is The Grill Gauge.

I’ve had a few devices that claim to measure the propane in your tank, including an inline gauge….

and a magnet you slap on the side of your tank that changes color according to the amount of propane in the tank.

Both gauges technically worked, but the readings were unreliable at best. When I first had an inline gauge, it read that I was on the line between red & yellow. I decided to have the tank topped off at Camping World in Indianapolis while on our way to a weekend camping trip. After the tech filled it, the bill was just $9 & change. Expecting the bill to be in the $15 range, I asked him if he filled it, and he told me that it was already half full. So, that’s when started looking for something else. I picked up the magnet thinking maybe this would do the trick. Well, I’m not sure if it did or not. The magnet is a series of bars that change color as the propane level drops. But figuring out which column of bars you’re supposed to read was a little confusing and made for a lot of guesswork.

Consumer Information

Tanks (or cylinders) that propane dealers most often fill are identified as “20.0 lb. tanks” – the most commonly used tanks for gas grills, bug zappers, and patio heaters.

The propane industry fills propane tanks by weight.

  • The Grill Gauge was engineered and custom calibrated to measure the “maximum allowable fill weight” of liquid propane for standard 20.0 lb. grill tanks.
  • The “maximum allowable fill weight” (determined by DOT regulations) ranges between 18 1/2 and 19 3/4 lbs. of liquid propane per 20.0 lb. tank (depending on the tank’s water capacity).
  • Not all propane dealers fill 20.0 lb. LP tanks to their “maximum allowable fill weights.”
  • Check the label on the propane tank to see what the net weight fill amount is:
    – For an example: a tank only filled to 15.0 lbs. of liquid propane is actually under-filled by approximately 25% of its “maximum safe-fill capacity.”
    – Propane fillers must label their cylinders with the lowest amount of gas that might be in their cylinders, not the maximum allowed capacity.
  • The darkest green (“F”) area of the Grill Gauge scale is calibrated for “net fill weights” between 18.0 and 19 3/4 lbs. of liquid propane – indicating the “maximum allowable net fill weight” for 20.0 lb. tanks
    – A 20.0 lb. tank that is “filled” less than the “maximum allowable net fill weight” will show less than FULL on the Grill Gauge, again because the Grill Gauge is calibrated for the maximum allowable net fill weight!
