Aluminum Alloy Visual Oil Flow Indicator for Fuel Dispensing Systems

The FGSYQ-4 Series Visual Oil Flow Indicator is designed to help operators easily check fuel flow during fueling operations.You just install it right between the dispenser hose and the nozzle, and it gives you an instant, firsthand look at whether fuel is moving through the line—no complicated monitoring rigs required.

Instead of fragile traditional glass that cracks the second it hits the pavement, this indicator uses a tough, transparent acrylic sight glass. Inside, there's a bright red rotor that spins like crazy the moment fuel starts flowing, so your operators can check the line status at a glance. The acrylic handles impacts, oil, and harsh weathering like a champ, and since the main body is lightweight aluminum alloy, it doesn't add a bunch of clunky weight to the nozzle. Sizing is pretty flexible too; you can get it in 3/4" or 1" options with both NPT and BSP threads, so it hooks up easily to standard hose couplings or swivels.

You'll see the FGSYQ-4 series deployed all over the place—from retail gas stations and LPG setups to heavy industrial fuel transfer lines. It's a simple, zero-fuss piece of hardware that lets you confirm flow in seconds, which honestly keeps your operations moving a lot faster and safer. If you just need a reliable, drop-in solution to keep tabs on your fuel lines, this thing gets the job done without a headache.
