What is a Hill sight check?
A sight check or sight flow indicator is a fitting with glass windows that lets you see liquid moving in a pipe. Some types include a flap or ball that moves with the flow, and some include a check function.
Operators can confirm flow, colour and clarity at a glance. Therefore, sight indicators are common on condensate, oil and process lines.
