Sight Glass | ASC | 1 in. FIPS x 1 in. FIPS | With 1/2 in. Restricted Orifice

This Bronze constructed Sight Glass features double-sided Acrylic windows to visually observe and monitor water flow characteristics, such as flow rate, flow direction, and/or any potential water flow issues during the testing process. With a 1 in. FIPS x 1 in. FIPS connection, installation and use is simple and easy. This model features a 1/2 in. Restricted Orifice to simulate water-flow in a water-based sprinkler system.

Is a Sight Glass Necessary for Flow testing?

To conduct an accurate water flow test, certain tools are necessary, such as pressure gauges, pitot tubes, pitot blades, and more depending on the specific test. While a sight glass is not inherently necessary for conducting accurate flow tests, we highly recommend using one anyways. Sight glasses are very useful for the following reasons:

- Flow Rate Observation: A sight glass allows operators to directly observe the movement and rate of fluid flow. By visually assessing the flow velocity and volume, they can verify if it matches the expected or desired flow rate for the testing application.
- Flow Direction Confirmation: The sight glass enables operators to confirm the flow direction visually, preventing any potential errors or reversals that could impact the accuracy of the test results.
- Detection of Air or Gas Entrapment: Air or gas entrapped within a fluid can affect flow rates and measurements. A sight glass can help identify air bubbles or gas pockets, allowing corrective action.
- Visualization of Sediment or Contamination: It helps detect any sediment, debris, or contaminants affecting test accuracy or system function.

Overall, sight glasses provide an extra level of confidence when testing. They help ensure the most accurate results by identifying certain variables that may not have been included without its use.
