Krueger Sentry Gauge can provide a high level overfill alarm (both visual and audible) to notify the person filling the tank that the fluid has reached 90 percent. This should satisfy step eleven on the inspection shee.

Diesel Exhaust Fluid Article- Don’t Turn a DEF ear to low DEF.
Don’t turn DEF ear to low diesel exhaust fluid
Diesel exhaust fluid (DEF for short) is becoming more common as a key ingredient in diesel engine emission controls. Introduced to North American car drivers in certain Mercedes vehicles in 2006, it spread to the heavy trucking industry in 2007. Now DEF has hit the Detroit Three light truck market.
Ford, GM and certain Dodge diesels trucks come with an extra tank to carry the DEF necessary to meet emission regulations (the Dodge Ram 2500 and 3500 series meet the regulations without a DEF system).
DEF is essentially a 32-per-cent urea-water solution that is injected at a variable rate into the vehicle’s catalytic converter to reduce nitrous-oxide (NOx) emissions.
The amount injected is calculated by the main engine computer and varies dependent on engine load and speed as well as operating temperatures and several other in-puts. DEF is used, on average, at a rate of three per cent of the amount of fuel consumed.
When the DEF stream hits the hot inner surfaces of the catalytic converter it vaporizes and decomposes to form ammonia and carbon dioxide.
The ammonia is then used to convert the NOx emissions to harmless nitrogen and water.
For those who think the system is just another piece of technology that can be ignored, think again. If a DEF tank is left to run dry, the engine will not start.
If the tank runs low while the engine is running, a series of warning messages and lights will appear on the instrument cluster but the vehicle will continue to run until it is switched off by the driver (and then of course it will not restart).
DEF on-board tanks will hold about 30 litres of the fluid. Four-litre jugs can be purchased from most aftermarket parts stores or dealerships (that sell DEF vehicles) for around $12. In the U.S. many heavy truck refuel-ling centres dispense DEF at bulk pumps next to regular fuelling stations for as little as $4 U.S. a gallon.

Sight Gauge Overview Part 1 -Standard Therma Gauge
This is the standard Therma Gauge Model designed to measure liquid level. The base construction for this sight gauge is galvanized wetted rods with HDPE Floats and an Aluminum Bushing. Other options are available for increased compatibility with various liquids.
This mechanical gauge is custom made in house to fit your tank. Our flexible production process allows for custom sizes that range from 6 inches to 144 inches in total length. We can also customize the level indicator to accommodate for double walls and pipe risers. For more info on sizes, see the Sight Gauge Order Help
- Diesel Fuel Gauge
- Gasoline Gauge (for longer life add the Glass Calibration. Increases resistance to fumes and heat.)
- Fuel Oil Gauge

Barrel Gauge – Now Available in All Stainless Steel Construction
The Liquid Level Barrel Gauge is now available in
All Stainless Steel Construction.
The Type B-Barrel Gauge can be purchased with all stainless steel wetted components. This includes the bushing, the wetted rods, and the floats.
In order to increase the level gauge’s compatibility with more aggressive liquids (including Caustics, DEF, E85, and more…) this gauge also comes standard with viton gaskets. The internal piece of the calibration is made of glass. This alternative gives the plastic calibration added resistance to internal fumes and all types of heat.

Overfill Gauge Alarms – New Options Available.
New models available for the Krueger Audible Overfill Prevention Alarms
The Audible Alarm accessory for the Krueger Gauge line of products has become a hot selling item. Able to provide audible overfill protection or audible low level warnings, it is a convenient and inexpensive solution. In response to feedback, we are now offering the Overfill Gauge Alarm in several new configurations. All of the configurations are available in both our remote mounted versions and direct mounted versions.
- DAlarm-FL and RAlarm-FL : With this model, the audible fill alarm is replaced with a flashing light. The flashing light will trigger with the magnetic sensor in the fill gauge and continues to flash until reset.
- Dalarm-FL-TO & RAlarm-FL-TO : With this model, there is an audible alarm, a flashing light, and a time out feature. When triggered, the alarm will sound for 20 seconds, then it will silence itself and chirp every few seconds. The flashing light will go until reset.
- DAlarm-DC-FL & RAlarm-DC-FL : This gauge alarm replaces the audible alarm with a set of dry contacts and a flashing light. The light will flash until reset.
- DAlarm-DC-FL-TO & RAlarm-DC-FL-TO : This version has dry contacts, audible alarm, flashing light, and a time out feature. The alarm itself will shut off after 20 seconds and begin to chirp until reset. The flashing light will go until reset as well.

Remote Liquid Level Gauge Monitor- Extreme Tests
LED At A Glance Remote Monitor – Liquid Level
The LED At A Glance, a remote display accessory for the Krueger line of liquid level gauges, has been put through some rigorous weather tests and has passed with flying colors.
Early in the winter season, we set up some liquid level gauges outside the shop mounted to some 55 gallon drums. The wires for the remote level monitors were then run over to the wall and the LED At A Glance remote level gauge displays were then set up in exposed areas.
LED At A Glance Remote Monitor – Liquid Level
Luckily, (for our testing purposes anyway), we got hit with a major snow storm. (18 inches of snow, 20 below zero with windchill).
Pictured above (the first picture) you can see the exposed remote display wire encased in ice.
Pictured directly above, you can see how the remote liquid level monitor itself was totally buried in snow and then dug out.
Although we do suggest placing a hood or some other sort protection over the level monitor, in all testing cases the remote liquid level monitor still worked great after the storm went through.

Chemical Sight Gauge for more aggressive liquids
Standard Krueger sight gauges are best known in the petroleum equipment industry for providing inexpensive yet reliable liquid level fill gauges for all types of tanks. Yet with the growing amount of alternative fuels including bio diesel and E-85, we found it advantageous to create sight gauge packages that include all stainless steel or all plastic components. This created an excellent side effect.
Our sight gauges can now handle extremely aggressive chemicals including Sulfuric Acid and Hydrochloric Acid. Some chemical sight gauge examples include:
- All stainless steel chemical fill gauge construction – E-85, Bio Diesel, Peroxide, Nitric Acid, Caustics, Calcium Chloride, KOH, and more.
- All plastic chemical sight gauge construction – Peek Plastic Option – Phosphoric Acid, Hydrochloric Acid, Bleach, and more.
- All plastic chemical fill gauge construction – Kynar Plastic Option – Chlorine, Sulfuric Acid, and more.

DEF -Diesel Exhaust Fluid Level Gauges
I have done some research, and I am proud to announce that the current Krueger Liquid Level Gauge product line will be fully compatible with the new DEF that will be hitting markets soon. I recommend any one of the following three material configurations.
- SSR – Stainless Steel Rods, the rest of the gauge is standard. This is compatible, and the least expensive option.
- AllSS – Stainless Rods, Stainless Floats, and a Stainless Bushing. This DEF level gauge is a tank. The top model of our gauges.
- AllPlastic – Peek Rods, HDPE Float, PVC bushing. This Diesel Exhaust Fluid Level gauge is extremely corrosion resistant and is fully compatible with DEF.

Overfill Prevention and Leak Detection Regulations
As most of you know, regulations on above ground storage tanks are getting more strict. Krueger Gauge has gotten some third party testing done on our Therma Tank Level Gauge and our Overfill Alert Gauge. The results have gotten us approved by Florida (FDEP) as an overfill prevention device on above ground storage tanks. We have not been informed at this point that we need any special approvals for other states, but you should check with your local governments for info on this. Special Documents are and ordering instructions are required for you to comply with some of these overfill regulations.
Also, some time ago, we were approved as a Leak detection gauge on double wall storage tanks in Florida as well. The documents documents for this are as follows.
