Polycarbonate flow sight glasses
“Polycarbonate” is a group of thermoplastics that are easy to work with, mold and thermoform, and are widely used in modern manufacturing. The name “polycarbonate” is based on the fact that they are polymers that have functional groups joined by carbonate groups in a long molecular chain.
OUR WARRANTY
100% Satisfaction Guarantee
Douglass warrants merchandise against defective workmanship and materials that become apparent within a period of 12 months from the date of receipt of invoice by the purchaser (hereinafter referred to as the warranty period).

Polycarbonate cylinders in 360° view sight flow indicators are prized for their exceptional clarity and impact resistance, making them suitable for a wide range of industrial monitoring applications. These cylinders offer a durable, lightweight alternative to glass that is capable of withstanding significant physical impacts without shattering. Ideal for environments where safety and the ability to observe fluid characteristics from all angles is paramount, polycarbonate indicators excel in applications not exposed to extreme temperatures or aggressive chemicals.
Their versatility allows for use in various industries including water treatment, food and beverage processing, and pharmaceuticals. The 360° visibility provided by these polycarbonate cylinders permits comprehensive monitoring of fluid flow, aiding in process control and safety measures.

Polycarbonate flow sight glasses — Applications and uses in industries
Polycarbonate flow sight glasses are essential components in various industries, providing a reliable solution for monitoring fluid flow in pipes and tanks. Their high impact resistance and lightweight nature make them ideal for environments where safety and durability are paramount. These sight glasses allow operators to visually inspect the flow of liquids and gases, enabling timely adjustments and ensuring optimal performance in processes. The transparency of polycarbonate materials ensures a clear view, which is crucial for maintaining the integrity of operations in sectors such as chemical processing, food and beverage, and pharmaceuticals.
In addition to their robust physical properties, polycarbonate flow sight glasses are versatile and can be used in a wide range of applications. They are commonly found in water treatment plants, oil and gas facilities, and manufacturing processes where monitoring fluid dynamics is critical.
Tubular sight glasses are used instead of polycarbonate sight glasses when greater impact and chipping resistance is desired, as well as when greater flexibility is desired for the sight glass.
