## Overview

The Groz 55-Gallon Drum Level Indicator is a rugged polyethylene gauge that mounts on a 3/4" NPT bung to provide an easy-to-read 0-55 gallon analog scale. Featuring a planetary gear-driven dial and an adjustable water-filled float, it accurately indicates fluid levels across oils, fuels, coolants, and water-based liquids. Its design frees the main 2" bung for pumps, making it ideal for industrial, automotive, and agricultural settings where timely fluid monitoring prevents downtime.

## Description

Stop opening drums just to check what's left. The Groz 48003 Drum Level Indicator threads into the 3/4" bung of a standard 55-gallon drum and gives crews an at-a-glance indicative reading from 0 to 55 gallons, so you know when to schedule the next drum before production stops.A planetary gear mechanism connects the dial to a polyethylene float on a string. As fluid drops, the float drops, and the gauge moves. The float is partially filled with water, and adjusting that water lets the same unit read sensibly across light oils, heavy oils, fuels, coolants, water-based fluids and similar liquids. An air release venturi is built into the threaded body for steady float travel.Because it mounts on the small 3/4" opening, the 2" bung stays free for a drum pump. Suited to oil and fuel drums in automotive shops, fleet bays, manufacturing, agriculture and industrial lube rooms. Note: this is not a precision measuring device; the gauge provides an approximate level only.

## Features

- KNOW WHEN TO REORDER AT A GLANCE - Stop guessing how much oil or fuel is left in your drum; the Groz DLI mounts on the 3/4" bung and shows an indicative 0-55 gallon level on a clear analog dial.
- DURABLE POLYETHYLENE CONSTRUCTION - Planetary gear mechanism drives the dial via a string-connected polyethylene float, built to handle oils, fuels, coolants, water-based fluids and a wide range of liquids in industrial drum service.
- ADJUSTABLE FOR DIFFERENT VISCOSITIES - Float is partially filled with water; add or remove water to tune buoyancy so the same unit reads accurately across light oils, heavy oils, fuels, coolants and other fluids in your shop.
- LEAVES THE 2-INCH BUNG FREE FOR PUMPS - Threads into the small 3/4" NPT opening on standard 55-gallon drums and includes an air release venturi, so your 2" bung stays open for hand or electric drum pumps.
- VERSATILE SHOP AND FLEET USE - Ideal for automotive shops, fleet maintenance, manufacturing lines, agricultural operations and lube rooms; gives an approximate fluid level so crews can arrange a new drum before run-out.

## Questions & Answers

**Q: Does this still allow the drum to vent? And has anyone use this on the B side of closed cell foam(polyol resin)?**
A: Not really which is kinda stupid. We use it for our oil drums and always have issues with venting, eventually we just removed it because it was more trouble then it’s worth.

**Q: is the gauge water tight to be installed in the utside ? I would hate to get condensation and not be able to read it....**
A: No It is not water tight.  Not for outdoor use.

**Q: where is it madE?**
A: Probably china

**Q: do you have a version that will fit on the 2'' port**
A: Check your 2” port cap, some of them have a 3/4” threaded hole in the middle. You’ll have to punch out or cut the hole, but this fit perfectly in mine. Note, I did buy and install a short 3/4” riser to allow the gauge to screw on snuggly onto the 2” cap.
