GREEN BAY, WI – October 22, 2026 – PRESSADVANTAGE –

Krueger Sentry Gauge, a manufacturer of mechanical liquid level measurement products, has outlined its current lineup of chemical tank level gauge products engineered for tanks that store corrosive and aggressive liquids. The company detailed the range of all-plastic and all-stainless-steel construction options available across its chemical gauge product category, addressing the material compatibility requirements that operators face when monitoring acids and other reactive media.

The chemical tank level gauge products are designed to detect the liquid level of chemicals stored in aboveground storage tanks and barrels. According to the company, the gauges support both operational efficiency and workplace safety by giving operators a reliable visual reading of tank contents. The product family includes swing-arm mechanical gauges, barrel gauges, and overfill alert gauges, each offered in construction materials selected for compatibility with specific stored substances.

Material compatibility sits at the center of the product line. Krueger Sentry Gauge manufactures several of its most widely used chemical level gauges in all-plastic construction to provide compatibility with more aggressive liquids and chemicals. The company noted that its gauges are used to monitor substances including sulfuric acid, hydrochloric acid, phosphoric acid, chlorine, bleach, acetone, and caustics, among others. Stainless steel variants extend the range of applications for facilities handling different classes of chemicals.

“Choosing the right level gauge for a chemical tank is not only about reading a number, it is about matching the wetted materials to whatever is inside that tank,” said Lee Geurts, Vice President of Krueger Sentry Gauge. “When an operator is storing something like sulfuric acid or chlorine, the wrong material can fail quickly. Offering these gauges in both all-plastic and all-stainless-steel construction lets us give each customer a gauge that stands up to the specific liquid they are monitoring.”

The Therma Type H level gauge, offered as the all-plastic Type PH and the all-stainless-steel Type H-S3, uses a swing-arm mechanical design intended for monitoring a wide range of liquid levels. The company stated that the mechanical design promotes durability, minimal upkeep, quick installation, and straightforward repairs. Cut sheets and owner documentation for the models are published in the company’s resource library.

The At A Glance liquid level gauge, available as the all-plastic Type PD and the stainless Type D-S2, provides another option for facilities working with aggressive chemicals. The company indicated that the all-plastic version is used to measure liquids such as chlorine, sulfuric acid, phosphoric acid, and bleach. Like other products in the line, the gauge is built around a mechanical reading mechanism rather than an electronic sensor.

For drum and barrel applications, the company offers the Chemical Barrel Gauge in all-plastic Type PB and all-stainless Type B-S3 configurations. The barrel gauge is a swing-arm fill gauge made specifically for standing and horizontal barrels, and it accommodates 55-gallon, 30-gallon, and 15-gallon drums. Multiple materials of construction allow the barrel gauge to serve a broad set of stored liquids, including phosphoric acid, sulfuric acid, hydrochloric acid, chlorine, and bleach.

The chemical gauge category also includes the Overfill Alert Gauge, available in all-plastic Type PO and all-stainless O-S3 construction. The company described the product as a high-level visual gauge designed to indicate when an aboveground storage tank is near full. Its pop-up mechanical design is intended to support easy installation, durability, and low upfront cost. A range of accessories, including alarm options and remote monitoring components, is available across the product line.

Krueger Sentry Gauge is based in Green Bay, Wisconsin, and manufactures mechanical liquid level gauges for the chemical, petroleum, wastewater, petrochemical, agriculture, railcar, aviation, and government and military sectors. The company also operates a machining division and maintains memberships and listings including the Petroleum Equipment Institute, the Better Business Bureau, and Underwriters Laboratories.

“Our customers tend to keep these gauges in service for a long time, and that comes down to the simplicity of the mechanical design,” Geurts said. “There are no batteries to replace and no electronics to fail. When something does need attention, the repair is usually quick and inexpensive, which matters a great deal in a chemical storage environment.”

The company noted that selecting an appropriate chemical tank level gauge depends on the stored substance, tank configuration, and monitoring needs of each facility. For more information on the chemical gauge product category and available construction materials, visit www.ksentry.com.
