Frequently Asked Questions

When should I choose a liquid-filled gauge instead of a dry gauge?

Choose liquid-filled when vibration or pulsation would cause the needle to chatter and make readings hard to trust. The fill fluid dampens movement, helping you see real pressure instead of noise. You'll notice the difference on pump skids and mobile equipment that never sits still.
They're also a smart fit at pump intake or discharge points where spikes happen during starts and stops. In those dynamic, rugged spots, a filled case protects accuracy and extends service life.

Where are these liquid-filled water pressure gauges commonly installed?

- Pump intake and discharge to verify suction and discharge conditions.
- Lines subject to vibration, pulsation, or shock where readings must stay stable.
- Systems using media that won’t clog ports or attack copper alloys.
- High-duty environments that demand reliable performance shift after shift.

Can these liquid-filled gauges handle heat, corrosion, and pressure spikes?

Yes. G&G Hydraulics Corporation stocks industrial-grade, liquid-filled designs for high-temperature and corrosive settings, with cases and internals specified for harsh duty. Selection depends on the medium and environment you're monitoring.
They’re also well-suited to installations where sudden shocks or spikes occur. These liquid-filled water pressure gauges’ fill fluid cushions the mechanism, so accuracy and readability stay consistent when equipment cycles or valves snap shut.
