Reliable Plastic Gauges for Potassium Hydroxide Storage Tanks
Safely and accurately monitor your potassium hydroxide storage tanks with Krueger Sentry Gauge’s corrosion-resistant, all-plastic liquid level gauges. Specifically designed for potassium hydroxide (KOH), our gauges ensure precise chemical level monitoring in both bulk tanks and drums. Made in America using chemically compatible materials, these gauges deliver lasting performance, regulatory compliance, and unmatched safety in aggressive alkaline environments.
Metal and Glass Level Gauges Fail in Potassium Hydroxide Storage
Potassium hydroxide storage presents specific challenges for facility managers and chemical engineers. Highly alkaline, KOH rapidly corrodes conventional metal gauges, even those constructed of stainless steel. Gauge corrosion leads directly to leaks, mechanical failures, and costly operational disruptions. Potassium hydroxide’s aggressive alkaline nature attacks metal fittings, fasteners, and valves, jeopardizing accurate monitoring and causing potentially hazardous leaks and spills.
Similarly, glass sight gauges—while resistant to chemical attack—pose significant risks due to their fragility. In industrial environments, a simple impact can fracture glass tubes, resulting in dangerous chemical releases. Leaks from gauge failures not only pose safety hazards but also risk regulatory non-compliance and environmental harm.
Compatibility with polyethylene (HDPE), polypropylene, or fiberglass tanks used for potassium hydroxide storage further complicates gauge selection. Double-wall tanks and extended pipe risers common in chemical storage facilities often can’t be accommodated by standard gauges, leaving gaps in essential monitoring practices.
The Solution: Krueger Sentry’s Potassium Hydroxide Tank Gauges
Krueger Sentry Gauge resolves these challenges with our specialized, all-plastic liquid level gauges designed explicitly for potassium hydroxide storage. Our gauges feature chemically resistant materials, eliminating corrosion and ensuring reliable, accurate monitoring over the long term. All gauge components that contact the KOH solution—support rods, floats, bushings, and threaded fittings—are constructed from robust, chemically inert plastics such as PVC, PVDF (Kynar®), and HDPE.
Our At-A-Glance® liquid level gauges provide instant, reliable visual readings without the risks associated with opening tanks or manual dipping. The mechanical float-and-rod design is simple, robust, and requires no external power, minimizing failure points and maintenance requirements. Gauge maintenance is significantly reduced, and replacement due to corrosion or mechanical failure becomes virtually unnecessary.
Manufactured in the U.S., each gauge is customized to precisely fit your tank dimensions. The gauges accommodate tank depths from 6 inches up to 110 inches and effectively manage double-wall tank designs or extended pipe risers through customizable extensions. Installation compatibility is seamless, integrating with standard NPT tank fittings.
Gauge Models: PD for Bulk Tanks and PB for Drums
Krueger Sentry Gauge offers tailored solutions for various storage needs. The Type PD gauge is ideal for bulk potassium hydroxide storage tanks, providing accurate, direct-reading level monitoring. This top-mounted gauge is customizable for tank depths from 6 inches to 110 inches, easily accommodating complex storage setups like double-wall tanks and risers.
For smaller-scale storage solutions, such as 55-gallon, 30-gallon, or 15-gallon drums, the Type PB gauge provides reliable, precise liquid level readings. This gauge is designed to install securely into standard drum openings, enhancing safety by eliminating manual checks and reducing exposure risks. Like the PD model, the PB gauge is constructed from chemically resistant plastics, ensuring long-term performance without corrosion.
Both gauge models feature simplicity and durability, significantly reducing the need for maintenance. Optional alarms or LED remote indicator capabilities can be added for enhanced operational control.
Advantages of Plastic Gauges over Metal and Glass In KOH Storage
Krueger Sentry’s plastic gauges significantly outperform traditional stainless steel and glass gauges in potassium hydroxide environments. While stainless steel gauges succumb rapidly to the corrosive nature of KOH, chemically inert plastics such as PVC, PVDF, and HDPE remain unaffected, delivering consistent performance without risk of corrosion-induced failure.
Unlike glass gauges prone to breakage and leakage, our plastic gauges are robustly constructed to withstand industrial handling. Internally mounted and protected within sturdy plastic housings, these gauges eliminate the risk of external damage and subsequent chemical release.
Long-term maintenance costs are drastically reduced with our plastic gauges. Facility managers benefit from fewer replacements, minimal routine maintenance, and longer lifespans compared to metal or glass gauges.
Enhanced Safety and Regulatory Compliance
Krueger Sentry’s gauges directly support regulatory compliance requirements for safe potassium hydroxide storage. Regulations mandate precise chemical monitoring, secondary containment, and chemical compatibility for equipment. Our gauges are explicitly designed to meet these standards, providing reliable monitoring solutions compatible with secondary containment systems, double-wall tanks, and closed-system vapor management.
Industry guidelines consistently recommend plastic components for potassium hydroxide applications, validating Krueger Sentry’s material selection and gauge design. Our gauges eliminate uncertainty surrounding chemical compatibility, simplifying compliance and safety audits.
Facility managers gain immediate operational benefits, including improved safety, reliable inventory management, and simplified regulatory compliance. Chemical plant engineers appreciate the straightforward installation, minimal maintenance, and compatibility with existing tank systems. Procurement teams value the dependable, cost-effective, and readily available gauge solutions manufactured domestically.

What do we use as a part number?
At Krueger Sentry, we don’t use classic part numbers. Everything is description-based. Refer to your product’s Spec Page (materials options) and the Order Info (tank measurements) page for more information. Example Part Number: – H-2-48 + 12 w/glass (H signifies the type of gauge, 2 is the size opening, 48 is the tank depth, 12 is the extension, and everything after that is the options you want to be included.
Which liquid level monitor is the right choice for me?
When choosing a liquid level gauge, different factors can change which sight gauge is best for you. The basic factors that motivate people to buy each type of gauge are as follows.
- Economical sight gauge- At-A-Glance Direct Reading
- Versatile sight gauge- Therma Gauge
- Small tank monitor, under 12 inches – The L Gauge
- Standard Barrel Level Gauges – Barrel Gauge
- Up to 12 feet of mechanical remote capability – Remote Reading Gauge
- Durability – GFK Gauge – you can achieve this durability by ordering a therma gauge with a gauge guard as well.

Which sight gauge do you recommend most often to your customers?
I try to sell the Therma gauge to most people. It is nearly as inexpensive as the At A Glance Gauge, but you have more control over your swing arm. Plus, this level gauge can be fitted with the most options.
What is the difference between the Type D At a Glance Level Gauge and the Type H Therma Level Gauge?
The Swing arm on the Type D Gauge is fixed. When you thread in the gauge, the swing arm spins inside the tank and will end up facing in a random direction. The swing arm on the Type H Gauge can be aimed in the exact direction you want it to swing, and when you thread the gauge in it does not spin inside the tank.
How long is the swing arm on a level gauge?
The arm is always half the depth of your tank.
How do I order a custom-size level gauge?
In order to get an accurate gauge for your tank, we take two measurements into consideration. First, we measure, in inches from top to bottom, what the distance is from empty to full, known as tank depth. Second, the distance from the full mark to the gauge fitting on top is also known as an extension length. Sometimes this measurement comes out to zero.
How do I prevent my tank gauge from getting damaged by the sun and weather?
Ordering upgraded options such as Solid Glass Tops and Gauge Guards will make your Krueger Gauge nearly impervious to weather, sun, and damage.
Can I repair just the top of my Tank Gauge, or do I need to replace the whole thing?
If your gauge still seems functional, you can replace just the top components by ordering the corresponding repair kit. Repair Kits are available for all gauge types and come in a variety of material options for added durability, which can be found in the Tank Gauge Accessories.
What is the recommended maintenance/testing for Krueger Leak Gauges?
