Tokico FGBB835BDL 1-Inch Oil Flowmeter
The Tokico FGBB835BDL is an FGB-series positive displacement meter for measuring accumulated oil volume. Its mechanical counter gives operators a local reading without an external power supply. The FGB measuring unit uses resin gear-type rotors.
This page offers two counter versions with the same 25 mm (1-inch) connection: 02X for accumulated volume only, and 04X when a separate counter must be reset after a delivery or transfer. Select the version that matches your existing meter or operating procedure.
Choose the counter version
| Model | Counter arrangement | Suitable when |
| FGBB835BDL-02X |
Seven-digit non-resettable totaliser |
You need a continuous accumulated volume reading. |
| FGBB835BDL-04X |
Seven-digit totaliser and five-digit resettable counter |
You need to read individual deliveries or transfers while retaining the accumulated total. |
