Our liquid-filled fuel pressure gauges are filled with high-viscosity glycerin to effectively absorb engine vibrations and pressure pulses, ensuring accurate readings and extending the service life of internal components. As a source factory with multiple automated production lines, Hangzhou East Asia Instruments supports mass customization and direct supply, eliminates middlemen, and provides you with market-competitive ex-factory prices and fast delivery guarantees.
Filled fuel pressure gauges are mainly used in industrial fuel system monitoring, hydraulic power units, fuel pump test benches and marine engine fuel lines.
The glycerin filling inside the gauge provides strong damping for the pointer, effectively eliminating mechanical vibrations caused by the fuel pump. This ensures stable pointer indication even in high-frequency fluctuation environments, significantly improving reading accuracy and efficiency.
The liquid lubrication environment reduces frictional losses of internal gears and connecting rods. Compared with dry-type meters, the wear rate of moving parts is reduced by 50%, effectively extending the replacement cycle by two to three years.
The liquid-filled sealing design completely isolates the instrument from ambient air, preventing fogging or water accumulation inside the gauge in high-humidity or rapidly fluctuating temperature industrial environments, thereby ensuring that the dial window remains consistently clear and transparent.
The case is made of high-quality 304 stainless steel and features liquid filling for added protection, effectively resisting chemical splashes and salt spray in industrial environments. This ensures the instrument remains rust-free even under harsh operating conditions.
Equipped with a compensating sealing plug, this instrument allows manual or automatic adjustment of the pressure balance between the inside and outside. This effectively addresses liquid expansion caused by ambient temperature fluctuations, ensuring that measurement accuracy remains within ±1%.
The internal pressure-sensing element is reinforced to withstand instantaneous overpressure up to 120% of the full-scale range without damage, significantly enhancing equipment safety during sudden pressure transients in the fuel line.

The liquid-filled fuel pressure gauge of Hangzhou East Asia Instrument eliminates the problem of pointer jitter during reading through precision filling process, and its reading stability is three times higher than that of traditional dry gauge under severe vibration environment. At the same time, our aviation-grade sealing technology ensures that the instrument achieves zero leakage under long-term cycle pressure.
responsible for the daily inspection of hydraulic and fuel systems in chemical plants and manufacturing plants, they need strong shock performance and durable pressure monitoring tools to reduce downtime maintenance time.
excavators, generator sets or large ship engine manufacturers, need to find stable quality and cost advantages of the source manufacturers for long-term batch support.
For the optimization of the fuel supply system of special vehicles or racing cars, high-precision, visually clear pressure gauges are required to monitor the working status of fuel pumps and pressure regulating valves in real time.
responsible for the overall operation of the energy or water supply station, paying more attention to the reliability of the product and the technical support provided by the manufacturer to ensure the uninterrupted operation of the monitoring system in the harsh industrial environment.
ensure that the fuel line is at zero pressure, check whether the thread of the joint matches, and wind the raw material tape if necessary to ensure tightness.
after the installation, please cut the sealing plug on the top of the instrument to a small opening or set it to the open position, and balance the internal and external air pressure to ensure the measurement accuracy.
the instrument should be installed vertically upward as far as possible to avoid uneven distribution of liquid caused by excessive tilt angle, thus affecting the running track of the pointer.
check the glycerin level in the meter once a quarter. If the liquid is turbid or seriously leaked, contact the manufacturer for replacement or maintenance in time.
