Bleach Storage Level Gauge Solutions

Easily Monitor Sodium Hypochlorite Levels Without Corrosion or Downtime

Reliable bleach (sodium hypochlorite) storage demands rock-solid inventory monitoring—yet conventional metal sight glasses pit, seize, and misreport within months of service. Inaccurate readings force emergency refills, maintenance crews scramble, and unplanned shutdowns chip away at production targets. Worse, every time a technician cracks open a hatch to “stick” the tank, they risk inhaling caustic chlorine vapors and violating OSHA respiratory-protection protocols.

At Krueger Sentry Gauge, we eliminate that headache.

Our all-plastic bleach storage tank level indicators are machined in the USA from UV-stabilized PVC, polypropylene, and NSF/ANSI 61-approved elastomers, providing uncompromised corrosion resistance in sodium hypochlorite up to 15 % by weight. With Krueger Sentry gauges in place, corrosion-related failures vanish and workers monitor inventory from a safe distance—no lid lifting, no fugitive fumes.

Customized Solutions for Bleach Storage

Whether you manage palletized drums or 12-foot bulk tanks, Krueger Sentry designs a gauge that drops in, seals fast, and stays accurate.

Barrels

  • PB Series gauges fit standard 55-, 30-, and 15-gallon drums with 2 in., 1.5 in., or 0.75 in. NPT bung threads. Each stem is factory-calibrated in eighths and quarters, simplifying chemical inventory checks during DOT hazmat audits.

Tanks

  • PD Series gauges adjust to tank depths from 17 in. up to 144 in. (6 in.–12 ft.) and accommodate double-wall sleeves or vertical pipe risers. HDPE floats track fluid density shifts, while glass-filled polypropylene guide rods shrug off hypochlorite’s oxidative stress for years.

Enhanced Safety and Convenience for Your Team

Facilities that once relied on dip sticks or corroding brass float gauges now record bleach levels through a clear PVC sight tube protected behind an impact-resistant guard. Operators remain outside of the vapor space, cutting personal-exposure points and aligning with the hierarchy of controls in 29 CFR 1910.1450. Safer procedures yield tighter compliance metrics and fewer near-miss reports.

We also offer accessories that elevate monitoring precision:

  • Audible alarms that trigger when levels hit your preset low or high thresholds.
  • LED remote indicators provide remote monitoring that mirror the local read-out up to 200 ft away, integrating with SCADA dry-contact inputs.
  • Protective Gauge Guards molded from polycarbonate for forklift-row environments and outdoor UV exposure.

Simple, Stress-Free Bleach Level Monitoring in Three Steps

  1. Customize Your Gauge—Select depth, connection size, and any double-wall or riser details online, or call our applications desk for rapid spec confirmation.
  2. Confirm Your Selection—Review the PDF drawing we email; verify flange pattern, gasket material, and float length match your tank or drum.
  3. Enjoy Worry-Free Monitoring—Install using the included PTFE gasket, torque per our chart, and log the calibration mark in your SOP. Accurate readings replace guesswork, corrosion concerns fade, and unplanned downtime shrinks.

With Krueger Sentry Gauge you remove corrosion risk from bleach storage—period. Trust the precision, durability, and safety of American-made chemical storage gauges relied upon by water-treatment plants, pulp-and-paper mills, and municipal bleach warehouses nationwide.

Frequently Asked Questions

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.

How do I find or locate a Krueger Sentry Gauge distributor?

Search our Preferred Distributor Page. Don’t see a distributor you want to use? Call me. Lee Geurts: 920-434-8860 ext 204

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?

Krueger Sentry provides a Leak Gauge Functionality / Calibration Testing Report with inspection procedures for inspectors/technicians. Please contact us with any questions.
