What Makes a Great Sight Glass? The Experts at Unibloc Weigh In

A sight glass, commonly known as a water gauge, is a specific type of level sensor, a transparent tube through which the operator of a tank or boiler can observe the level of liquid contained within. An effective sight glass might be just a plastic or glass tube connected to the bottom of the specific tank at one end and the top of the tank at the other. The level of liquid in your sight glass accurately displays the level of liquid in the tank.

A sight glass on a boiler, or any container holding potentially hazardous liquid, needs to be inspected periodically and replaced if it wears thin and failure in service can still occur. It’s important to work with a reputable supplier that won’t leave you scrambling for a replacement if this happens, or better yet, invest in high quality first and foremost. Put your faith in the quality of your sight glass and protect your investment and your workday.

Unibloc designs sight glasses that are specially designed for use in the pharmaceutical, biotech, food and beverage, chemical, and personal care industries, helping meet the manufacturing needs for virtually any type of liquid or processing requirements. Each of Unibloc’s high-quality sight glasses offer a stainless-steel construction, electropolished components, and the finest surface finishes as standard features that provide for more durability and expert craftsmanship.

Unibloc’s trusted sight glasses come in two varieties: the Bulls-Eye or the In-Line, both of which offer superior performance for high and low-pressure situations. Both styles and designs have applications they are best suited for, and it’s important to fully understand when you need each type.

Unibloc’s Bulls-Eye sight glass is fitted with two rigid glass view-ports on opposite sides for versatility in positioning or repositioning the equipment as needed. Inside the retainers in each sight glass are special gaskets, as well as a fine threaded ring, that keeps the sight glass disks in place. A Unibloc Bulls-Eye sight glass is ideal for extra protection while monitoring and observing your active process.

Unibloc’s industry-leading designers, engineers, and customer service representatives work together to carefully examine every part for quality, procure the strongest materials, and ensure there’s no disruption in the work day as the result of a failed sight glass. The acrylic glass option adds extra durability and is available on every bulls-eye sight glass at Unibloc.

Used in industrial boiler level gauges and applications to display and read the level, the specially designed groove in in-line sight glass makes the liquid reading clearer. The glass used will need to be finely ground, polished, and toughened during processing to make sure it’s strong and highly transparent. It must also be resistant the erosion of the liquid in the boiler.

For high-pressure or potentially hazardous liquids and industries where safety concerns are prominent, opting for Unibloc’s in-line sight glass is an excellent choice. Count on quality in-line sight glasses from Unibloc.
