Fluid Level Gauges
Fluid Level Gauges with Superior Clarity and Leak-Proof Design
A fluid level gauge, also known as a fluid level indicator, is a device used to measure and display the level of liquid (such as oil, coolant, fuel, or hydraulic fluid) inside a tank, reservoir, or gearbox. It allows operators to monitor fluid levels quickly and accurately, helping prevent damage from low fluid conditions.
JUNWELL’s fluid level gauge features crystal-clear visibility and a robust, leak-proof design, allowing operators to easily check oil levels, ensuring safe and efficient system operation.
Our fluid level gauges are widely used in hydraulic systems in construction equipment, agricultural machinery, marine vessels, commercial vehicles, and special machinery. JUNWELL’s fluid level gauges deliver reliable performance and long-lasting durability.
LS
Please note the distance between two screws when boring the two holes on the oil tank.
The recommended torque is 8-10 Nm when tightening the fluid level gauge.
A thermometer may be added to detect the actual temperature.
Max. working temperature: 80ºC (176ºF)
Patent No. PAT108447
LG
The outer shield of LG Fluid Level Gauge is made of aluminium.
Fluid level gauge LG series should be locked from inside of the oil tank with screws only. O- ring must be put in the groove to avoid being damaged when screwing.
The thermometer reading is just for reference. A thermometer gauge cannot be added onto the LG series.
Max. working temperature: 80ºC (176ºF)
The recommended torque is 8-10 Nm when tightening the fluid level gauge.
Patent No. 216295
LA
The main material used in LA fluid level gauge series is acrylic.
The recommended torque is 8-10 Nm when tightening the fluid level gauge. Please confirm the O-rings are put in the grooves properly to avoid any damage of O-rings.
Cannot be exposed to organic solvent.
A thermometer gauge may be added to detect the actual temperature.
Max. working temperature: 80ºC (176ºF)
OLI
OLI fluid level gauge is made of polyamide. It can resist the acidity and alkalinity of oil. It would be damaged by alcoholic liquid.
Max. working temperature: 105ºC (221ºF) at normal pressure The recommended torque is 8 Nm when tightening the oil level indicator.
HEX-GAS
The material of the body is polyamide and the seal is N.B.R synthetic rubber.
Max. working temperature: 105ºC (221ºF) at normal pressure
The recommended torque is 10-12 Nm when
tightening the oil level indicator.
OS
Oil indicator is transparent because of a special polyamide material. It improves appearance and visibility.
Resistant to oil solvents, grease and other chemical agents. Max. working temperature：105 ºC (221 ºF) at normal pressure
OS series
Installation: plug-in
It can only be used in the oil tanks with small pressure or no pressure.
HEX-M
Oil indicator is transparent because of a special polyamide material. It improves appearance and visibility.
Resistant to oil solvents, grease and other chemical agents.
Max. working temperature：105 ºC (221 ºF) at normal pressure
HEX series
Installation: thread-in
The recommended torque is ≒ 1.5~1.8 kg-cm (0.147~0.176 Nm) when tightening the oil level indicator.
